ACIP: Health workers, long-term care residents first tier for COVID-19 vaccine
The Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices voted 13-1 that both groups be in the highest-priority group for vaccination. As such, ACIP recommends that both be included in phase 1a of the committee’s allocation plan.
The recommendation now goes to CDC director Robert Redfield, MD, for approval. State health departments are expected to rely on the recommendation, but ultimately can make their own decisions on how to allocate vaccine in their states.
“We hope that this vote gets us all one step closer to the day when we can all feel safe again and when this pandemic is over,” said Nancy Messonnier, MD, director of the CDC’s National Center for Immunization and Respiratory Diseases, at today’s meeting.
Health care workers are defined as paid and unpaid individuals serving in health care settings who have the potential for direct or indirect exposure to patients or infectious materials. Long-term care residents are defined as adults who reside in facilities that provide a variety of services, including medical and personal care. Phase 1a would not include children who live in such facilities.
“Our goal in phase 1a with regard to health care personnel is to preserve the workforce and health care capacity regardless of where exposure occurs,” said ACIP panelist Grace Lee, MD, MPH, professor of paediatrics at Stanford (Calif.) University. Thus vaccination would cover clinical support staff, such as nursing assistants, environmental services staff, and food support staff.
“It is crucial to maintain our health care capacity,” said ACIP member Sharon Frey, MD, clinical director at the Center for Vaccine Development at Saint Louis University. “But it’s also important to prevent severe disease and death in the group that is at highest risk of those complications and that includes those in long-term care facilities.”
CDC staff said that staff and residents in those facilities account for 6% of COVID-19 cases and 40% of deaths.
But Helen Keipp Talbot, MD, associate professor of medicine at Vanderbilt University, Nashville, Tenn., voted against putting long-term care residents into the 1a phase. “We have traditionally tried a vaccine in a young healthy population and then hope it works in our frail older adults. So we enter this realm of ‘we hope it works and that it’s safe,’ and that concerns me on many levels particularly for this vaccine,” she said, noting that the vaccines closest to FDA authorization have not been studied in elderly adults who live in nursing homes or assisted living facilities.
She added: “I have no reservations for health care workers taking this vaccine.”
Prioritization could change
The phase 1a allocation fits within the “four ethical principles” outlined by ACIP and CDC staff Nov. 23: to maximize benefits and minimize harms, promote justice, mitigate health inequities, and promote transparency.
“My vote reflects maximum benefit, minimum harm, promoting justice and mitigating the health inequalities that exist with regard to distribution of this vaccine,” said ACIP Chair Jose Romero, MD. Romero, chief medical officer of the Arkansas Department of Health, voted in favor of the phase 1a plan.
He and other panelists noted, however, that allocation priorities could change after the FDA reviews and authorizes a vaccine.
The FDA’s Vaccines and Related Biological Products Advisory Committee (VRBPAC) will meet December 10 to review the Pfizer/BioNTech’s messenger RNA-based vaccine (BNT162b2). The companies filed for emergency use on November 20.
A second vaccine, made by Moderna, is not far behind. The company reported on Nov. 30 that its messenger RNA vaccine was 94.1% effective and filed for emergency use the same day. The FDA’s VRBPAC will review the safety and efficacy data for the Moderna vaccine on Dec. 17.
“If individual vaccines receive emergency use authorization, we will have more data to consider, and that could lead to revision of our prioritization,” said ACIP member Robert Atmar, MD, John S. Dunn Research Foundation Clinical Professor in Infectious Diseases at Baylor College of Medicine, Houston.
ACIP will meet again after the Dec. 10 FDA advisory panel. But it won’t recommend a product until after the FDA has authorized it, said Amanda Cohn, MD, senior advisor for vaccines at the CDC’s National Center for Immunization and Respiratory Diseases.
Staggered immunization subprioritization urged
The CDC staff said that given the potential that not enough vaccine will be available immediately, it was recommending that health care organizations plan on creating a hierarchy of prioritization within institutions. And, they also urged staggering vaccination for personnel in similar units or positions, citing potential systemic or other reactions among health care workers.
“Consider planning for personnel to have time away from clinical care if health care personnel experience systemic symptoms post vaccination,” said Sarah Oliver, MD, MSPH, from the CDC.
The CDC will soon be issuing guidance on how to handle systemic symptoms with health care workers, Dr. Oliver noted.
Some 40 million doses of the Pfizer/BioNTech and Moderna vaccines are expected to be available by the end of December, with 5 million to 10 million a week coming online after that, Dr. Cohn said. That means not all health care workers will be vaccinated immediately. That may require “subprioritization, but for a limited period of time,” she said.
Dr. Messonnier said that, even with limited supplies, most of the states have told the CDC that they think they can vaccinate all of their health care workers within 3 weeks – some in less time.
The ACIP allocation plan is similar to but not exactly the same as that issued by the National Academy of Sciences, Engineering, and Medicine, which issued recommendations in October. That organization said that health care workers, first responders, older Americans living in congregate settings, and people with underlying health conditions should be the first to receive a vaccine.
ACIP has said that phase 1b would include essential workers, including police officers and firefighters, and those in education, transportation, and food and agriculture sectors. Phase 1c would include adults with high-risk medical conditions and those aged 65 years or older.

Patient health suffers amid pandemic health care shortages
More than half (56%) of responding clinicians reported seeing a decline in patient health because of delayed or inaccessible care amid the pandemic, according to the results of the latest survey by the Larry A. Green Center and the Primary Care Collaborative. The survey was conducted in mid-October and the results were published online Nov. 17.
In addition, 37% of respondents said their patients with chronic conditions showed “noticeably worse health resulting from the pandemic.” And a resounding 85% said patient mental health had worsened.
“I think it’s worse than we thought,” said Rebecca Etz, PhD, codirector of the Larry Green Center. “It’s the outcome of not sufficiently sending resources to primary care either before or during the pandemic.” According to Dr. Etz, survey respondents noted substantial increases in patient weight gain as well as weight loss, anxiety and depression, sleep issues, domestic abuse, and poor oral and eye health, among others.
One clinician from Pennsylvania wrote: “Patients are becoming sicker during the pandemic. I’m seeing more uncontrolled [diabetes]and new [patients with diabetes]. They prefer telehealth yet [have] no access to glucose monitoring or a blood pressure cuff. I am concerned about patients’ isolation and mental health. People are delaying care.”
Now, with COVID numbers peaking across much of the country, many clinicians are trying to close the gap in care with telehealth – something they’re more prepared to do now than they were in March. Over two-thirds of practices are using telehealth for visits to keep up with patients who have stable chronic conditions, according to the survey.
Over 60% of physicians report using telehealth for mental health visits. But a much smaller number – only 16% of respondents – said their practice had added staff to help manage the rising number of behavioral and mental health cases. About one-third (35%) of practices say they’re not financially able to take on new staff.
“We’ve been looking for more ways for patients to do self-support. A big part of chronic disease is health behaviors,” Alex Krist, MD, MPH, a family doctor in Fairfax, Va., and chairperson of the U.S. Preventive Services Task Force, said in an interview. And unfortunately, on top of limited access to basic care, healthy habits that are essential to managing many chronic conditions have become more difficult and less consistent during the pandemic.
The survey – the 22nd iteration in a series of surveys the Green Center and the Primary Care Collaborative have conducted – received 580 respondents from 47 states and Guam. Over two-thirds of respondents were primary care physicians (MDs and DOs). Over half were owners, partners, or employees of a private practice, 66% of which were family medicine practices. And one fifth of respondents provided care in a rural area.
Funding and support for primary care has been wildly insufficient, Dr. Etz said in an interview. If that doesn’t change, patient health, clinic staffing, and public health strategies amid the pandemic will continue to suffer.
“When you think of the COVID vaccine, who do you think is going to be sending that out?” Dr. Etz asked. “If we don’t bolster primary care now how are they going to handle that.”

Moderna filing for FDA emergency COVID-19 vaccine approval, reports 94.1% efficacy
The Moderna COVID-19 vaccine in development was 94.1% effective in the final analysis of its 30,000-participant phase 3 study. Bolstered by the new findings, the company plans to file for an emergency use authorization (EUA) from the Food and Drug Administration (FDA) today, according to a company release.
A total of 11 people in the mRNA-1273 vaccinated group later tested positive for COVID-19, compared with 185 participants given two placebo injections, resulting in a point estimate of 94.1% efficacy. This finding aligns with the 94.5% efficacy in interim trial results announced on November 16, as reported by Medscape Medical News.
Furthermore, Moderna announced that the vaccine prevented serious cases of infection. All 30 severe infections occurred among those people randomly assigned to placebo.
The FDA plans to review the Moderna vaccine safety and efficacy data at the next Vaccines and Related Biological Products Advisory Committee (VRBPAC) meeting scheduled for December 17. If and when approved, healthcare providers can use the new 91301 CPT code specific to mRNA-1273 vaccination.
“This positive primary analysis confirms the ability of our vaccine to prevent COVID-19 disease with 94.1% efficacy and, importantly, the ability to prevent severe COVID-19 disease,” said Stéphane Bancel, MBA, MEng, chief executive officer of Moderna, in the news release. “We believe that our vaccine will provide a new and powerful tool that may change the course of this pandemic and help prevent severe disease, hospitalizations, and death.”
Vaccine efficacy remained consistent across different groups analyzed by age, race/ethnicity, and gender. The 196 COVID-19 cases in the trial included 33 adults older than 65 years and 42 people from diverse communities, including 29 Hispanic or Latinx, six Black or African Americans, four Asian Americans, and three multiracial participants, the company reported.
No serious vaccine-related safety issues
The mRNA-1273 vaccine was generally well tolerated and no serious safety concerns with the vaccine have been identified to date, the company reported.
Injection site pain, fatigue, myalgia, arthralgia, headache, and erythema/redness at the injection site were the most common solicited adverse events in a prior analysis. The company noted that these solicited adverse reactions increased in frequency and severity after the second vaccine dose. A continuous review of safety data is ongoing.
One COVID-19-related death in the study occurred in the placebo group.
Ready to start shipping
Moderna expects to have approximately 20 million doses of mRNA-1273 available in the United States by the end of this year. The company reports that it’s on track to manufacture 500 million to 1 billion doses globally in 2021.
The company also is seeking approval from nations and organizations worldwide, including a conditional approval from the European Medicines Agency (EMA). The study is being conducted in collaboration with the National Institute of Allergy and Infectious Diseases (NIAID) and the Biomedical Advanced Research and Development Authority (BARDA), part of the Office of the Assistant Secretary for Preparedness and Response at the US Department of Health and Human Services.
Moderna will be the second company to file an EUA with the FDA for a COVID vaccine, after Pfizer requested one for its mRNA vaccine earlier this month.

“This positive primary analysis confirms the ability of our vaccine to prevent COVID-19 disease with 94.1% efficacy and, importantly, the ability to prevent severe COVID-19 disease,” said Stéphane Bancel, MBA, MEng, chief executive officer of Moderna, in the news release. “We believe that our vaccine will provide a new and powerful tool that may change the course of this pandemic and help prevent severe disease, hospitalizations, and death.”
Vaccine efficacy remained consistent across different groups analyzed by age, race/ethnicity, and gender. The 196 COVID-19 cases in the trial included 33 adults older than 65 years and 42 people from diverse communities, including 29 Hispanic or Latinx, six Black or African Americans, four Asian Americans, and three multiracial participants, the company reported.
No serious vaccine-related safety issues
The mRNA-1273 vaccine was generally well tolerated and no serious safety concerns with the vaccine have been identified to date, the company reported.
Injection site pain, fatigue, myalgia, arthralgia, headache, and erythema/redness at the injection site were the most common solicited adverse events in a prior analysis. The company noted that these solicited adverse reactions increased in frequency and severity after the second vaccine dose. A continuous review of safety data is ongoing.
One COVID-19-related death in the study occurred in the placebo group.
Ready to start shipping
Moderna expects to have approximately 20 million doses of mRNA-1273 available in the United States by the end of this year. The company reports that it’s on track to manufacture 500 million to 1 billion doses globally in 2021.
The company also is seeking approval from nations and organizations worldwide, including a conditional approval from the European Medicines Agency (EMA). The study is being conducted in collaboration with the National Institute of Allergy and Infectious Diseases (NIAID) and the Biomedical Advanced Research and Development Authority (BARDA), part of the Office of the Assistant Secretary for Preparedness and Response at the US Department of Health and Human Services.
Moderna will be the second company to file an EUA with the FDA for a COVID vaccine, after Pfizer requested one for its mRNA vaccine earlier this month.

Blood glucose on admission predicts COVID-19 severity in all
Hyperglycemia at hospital admission – regardless of diabetes status – is a key predictor of COVID-19-related death and severity among noncritical patients, new research from Spain finds.
The observational study, the largest to date to investigate this association, was published online Nov. 23 in Annals of Medicine by Francisco Javier Carrasco-Sánchez, MD, PhD, and colleagues.
Among more than 11,000 patients with confirmed COVID-19 from March to May 2020 in a nationwide Spanish registry involving 109 hospitals, admission hyperglycemia independently predicted progression from noncritical to critical condition and death, regardless of prior diabetes history.
Those with abnormally high glucose levels were more than twice as likely to die from the virus than those with normal readings (41.4% vs 15.7%). They also had an increased need for a ventilator and intensive care unit (ICU) admission.
“These results provided a simple and practical way to stratify risk of death in hospitalized patients with COVID-19. Hence, admission hyperglycemia should not be overlooked, but rather detected and appropriately treated to improve the outcomes of COVID-19 patients with and without diabetes,” Dr. Carrasco-Sánchez and colleagues wrote.
The findings confirm those of previous retrospective observational studies, but the current study “has, by far, the biggest number of patients involved in this kind of study [to date]. All conclusions are consistent to other studies,” Dr. Carrasco-Sánchez, of University Hospital Juan Ramón Jiménez, Huelva, Spain, said in an interview.
However, a surprising finding, he said, “was how hyperglycemia works in the nondiabetic population and [that] glucose levels over 140 [mg/dL] ... increase the risk of death.”
Pay attention to even mild hyperglycemia from admission
The study also differs from some of the prior observational ones in that it examines outcome by admission glycemia rather than during the hospital stay, therefore eliminating the effect of any inpatient treatment, such as dexamethasone, he noted.
Although blood glucose measurement at admission is routine for all patients in Spain, as it is in the United States and elsewhere, a mildly elevated level in a person without a diagnosis of diabetes may not be recognized as important.
“In patients with diabetes we start the protocol to control and treat hyperglycemia during hospitalization. However, in nondiabetic patients blood glucose levels under 180 [mg/dL], and even greater, are usually overlooked. This means there is not a correct follow-up of the patients during hospitalization.
“After this study we learned that we need to pay attention to this population ... who develop hyperglycemia from the beginning,” he said.
The study was limited in that patients who had previously undiagnosed diabetes couldn’t always be distinguished from those with acute “stress hyperglycemia.”
However, both need to be managed during hospitalization, he said. “Unfortunately, there is high variability in inpatient glucose management. The working group of diabetes of the Spanish Society of Internal Medicine is working on specific protocols,” said Dr. Carrasco-Sánchez.
All-cause death, progress to critical care higher with hyperglycemia
The retrospective, multicenter study was based on data from 11,312 adult patients with confirmed COVID-19 in 109 hospitals participating in Spain’s SEMI-COVID-19 registry as of May 29, 2020. They had a mean age of 67 years, 57% were male, and 19% had a diagnosis of diabetes. A total of 20% (n = 2,289) died during hospitalization.
Overall all-cause mortality was 41.1% among those with admission blood glucose levels above 180 mg/dL, 33.0% for those with glucose levels 140-180 mg/dL, and 15.7% for levels below 140 mg/dL. All differences were significant (P < .0001), but there were no differences in mortality rates within each blood glucose category between patients with or without a previous diagnosis of diabetes.
After adjustment for confounding factors, elevated admission blood glucose level remained a significant predictor of death. Compared to < 140 mg/dL, the hazard ratios for 140-180 mg/dL and > 180 mg/dL were 1.48 and 1.50, respectively (both P < .001). (Adjustments included age, gender, hypertension, diabetes, chronic obstructive pulmonary disease, lymphopenia, anemia (hemoglobin < 10 g/dL), serum creatinine, C-reactive protein > 60 mg/L, lactate dehydrogenase > 400 U/L and D-dimer >1000 ng/mL.)
Length of stay was 12, 11.5, and 11.1 days for those with admission blood glucose levels > 180, 140-180, and < 140 mg/dL, respectively (P = .011).
Use of mechanical ventilation and admission to intensive care also rose with higher admission blood glucose levels. For the composite of death, mechanical ventilation, and/or ICU admission, odds ratios for 140-180 mg/dL and > 180 mg/dL compared with < 140 mg/dL were 1.70 and 2.02, respectively (both P < .001).
The study was supported by the Spanish Federation of Internal Medicine. The authors have reported no relevant financial relationships.

Approval of COVID-19 vaccines will change nature of clinical trials
While stressing the urgent need to vaccinate the whole U.S. population, infectious disease experts and medical ethicists are raising questions about the clinical trials needed to answer important questions about the new COVID-19 vaccines.
In a statement released on Nov. 20, Barbara Alexander, MD, president of the Infectious Diseases Society of America (IDSA) and a professor at Duke University, Durham, N.C., commented on Pfizer and BioNTech’s application to the Food and Drug Administration for an emergency use authorization (EUA) for its COVID-19 vaccine. Besides emphasizing the need for a transparent review of the companies’ trial data prior to the FDA’s granting an EUA, she said, “If emergency use authorization is granted, clinical trials and data collection must continue.”
In an interview, Dr. Alexander said she is convinced that both Pfizer and Moderna, which is also expected to seek an EUA soon, will continue their clinical trials to monitor the long-term safety and efficacy of their vaccines.
“The EUA guidance for COVID vaccine authorization is very clear that clinical trials will move forward,” she said. “Any EUA request would have to include a strategy to ensure that the long-term safety and efficacy of a vaccine could be monitored. I see no evidence that either Pfizer or Moderna is not prepared to follow those regulations.”
Eventually, she added, the drug makers will have to seek full FDA approval to replace an EUA, which as its name signifies, is designed for public health emergencies. “The EUA is a tool to help us get the vaccine into circulation and have it start working as quickly as possible in the current health crisis,” she said. “But once the crisis is over, if the sponsors want to continue to market their vaccines, they have to go forward and get full approval.”
Medical ethicists, however, point out there may be ethical and practical dilemmas involved in continuing or initiating clinical trials once a vaccine has been approved for use even on an emergency basis.
In a commentary in Annals of Internal Medicine, Rafael Dal-Re, MD, PhD, Arthur L. Caplan, PhD, and two other ethicists stipulated that the pandemic requires early licensing and deployment of COVID-19 vaccines. Nevertheless, they noted, additional months of data are required to establish the long-term efficacy and safety of the vaccines. “Moreover, early deployment could interfere with the acquisition of long-term data,” both on these vaccines and on others coming through the pipeline, they wrote.
In countries where an approved vaccine is deployed, the ethicists noted, investigators must inform participants in an ongoing trial about the approved vaccine’s status and ask if they want to continue in the study. If enough participants decline, the trial might have to be terminated early. At that point, researchers may not have sufficient long-term data to identify late-term safety issues, determine how long efficacy lasts, determine whether waning immunity is associated with reduced levels of antibodies, or identify the level of neutralizing antibodies that correlates with immunity.
Moreover, they observed, long-term trials are especially important for vaccines that use mRNA technology, because less is known about them than about traditional kinds of vaccines.
The authors also pointed out that early licensing of any vaccine might make it harder to evaluate vaccines that haven’t yet been approved. “Once a vaccine is licensed, new placebo-controlled RCTs [randomized controlled trials] of other vaccines will not be acceptable ethically, and noninferiority RCTs will be the most likely alternative.
“The goal of noninferiority trials will be to demonstrate that the immune response (that is, neutralizing antibody titers or levels) of the candidate vaccine is not inferior to that of the approved vaccine within a prespecified margin, which the FDA has established as less than 10% for COVID-19 vaccines,” the authors noted.
More data with more study designs
Dial Hewlett Jr., MD, medical director for disease control services, Westchester County Department of Health, White Plains, N.Y., said in an interview that the ethicists raise important issues that have been discussed in other forums, including a recent webinar of the National Academy of Medicine.
“As the authors point out, once you have a vaccine that has been shown to be effective and safe, it’s no longer ethical to enroll people in placebo trials,” he said.
Therefore, he said, Pfizer and Moderna will undoubtedly offer their vaccines to the people in their studies’ placebo groups after the vaccines receive an EUA. Then they will follow everyone who has been vaccinated for 2 years to determine long-term safety. Efficacy will also continue to be measured as an adjunct of safety, he said.
With regard to the difficulty of reconsenting individuals to enter a new clinical trial after a vaccine has been approved, he said, “I’d agree that trying to get all the same participants to come into another study would be a challenge. You can, however, design studies that will allow you to obtain the same information. You will have a large number of people out there who haven’t been vaccinated, and you can do single-arm longitudinal studies and measure a number of things in the individuals who are enrolled in those studies,” he said.
“You can look at the immunologic markers, both antibody and T-cell. You can follow these individuals longitudinally to see if they do develop disease over a period of time. If they do, you can determine what their levels of response were,” he added. “So there are opportunities to design studies that would give you some of the same information, although it would not be in the same population that was in the randomized trials.”
For newer vaccines that have yet to be tested, he said, developers can compare “historical controls” from the trials of approved vaccines, i.e., data from the unvaccinated participants in those studies, with the data from inoculating people with the novel agents. The historical data can be sex- and age-matched, among other things, to individuals in the new trials. Moreover, because the study protocols have been harmonized for all trials under Operation Warp Speed, it doesn’t matter what kind of vaccine they’re testing, he said.
It may be necessary to do additional studies to find out how long immunity lasts after people have been vaccinated, Dr. Hewlett pointed out.
“You may have a different trial design. You don’t need a control arm to determine how long immunity lasts. You’re just comparing the patients who were vaccinated to nothing,” he said. “So you could have a single-arm trial on a group of people who consent to be immunized and followed. You can see what their antibody levels are and other surrogate markers, and you can see when they might develop disease, if they do. You’d need a large sample, but you can do that.”
Dr. Hewlett noted that additional studies will be required to determine whether the new vaccines stop transmission of the coronavirus or just prevent symptoms of COVID-19. Until it’s established that a vaccine halts transmission or the country achieves herd immunity, he said, “we’ll still have to wear masks and take other precautions, because a significant portion of people will still be at risk.”
‘A lot of redundancy’
Dr. Alexander emphasized that any safety or efficacy issues with the first COVID-19 vaccines must be identified before the vaccine is offered to a large portion of the U.S. population.
“While the data from the Pfizer and Moderna trials are said to be favorable, we at IDSA want to make sure that whatever vaccine comes to market is safe,” she said. “Having an unsafe vaccine on the market would be worse than no vaccine, because you’re compromising the public confidence. We have to make sure the public trusts the process and that sufficient data have been evaluated to ensure the vaccine is safe and efficacious.
“I believe the FDA is being very careful and thoughtful in [its] response,” Dr. Alexander said. “They realize how important it is to get a vaccine and save lives. While they’re doing things differently and moving much faster than before, they’re still trying to be thoughtful and reasonable. They don’t seem to be putting people at risk or circumventing the regulatory standards.”
Moreover, she pointed out, the FDA’s Vaccines and Related Biological Products Advisory Committee, which is expected to meet on Dec. 10, will review the trial data before the agency grants an EUA to Pfizer or Moderna. Then the FDA will post the data publicly.
The next step is for the Advisory Committee on Immunization Practices of the Centers for Disease Control and Prevention to look at the data and decide who in the United States should receive the vaccine first, she pointed out. And both Pfizer and Moderna have shown their data to advisory panels of outside experts.
“There’s a lot of redundancy, and a lot of people are looking at the data,” Dr. Alexander said. “So I don’t think we’re cutting corners to get it out there more quickly.”

“There’s a lot of redundancy, and a lot of people are looking at the data,” Dr. Alexander said. “So I don’t think we’re cutting corners to get it out there more quickly.”

While stressing the urgent need to vaccinate the whole U.S. population, infectious disease experts and medical ethicists are raising questions about the clinical trials needed to answer important questions about the new COVID-19 vaccines.
In a statement released on Nov. 20, Barbara Alexander, MD, president of the Infectious Diseases Society of America (IDSA) and a professor at Duke University, Durham, N.C., commented on Pfizer and BioNTech’s application to the Food and Drug Administration for an emergency use authorization (EUA) for its COVID-19 vaccine. Besides emphasizing the need for a transparent review of the companies’ trial data prior to the FDA’s granting an EUA, she said, “If emergency use authorization is granted, clinical trials and data collection must continue.”
In an interview, Dr. Alexander said she is convinced that both Pfizer and Moderna, which is also expected to seek an EUA soon, will continue their clinical trials to monitor the long-term safety and efficacy of their vaccines.
“The EUA guidance for COVID vaccine authorization is very clear that clinical trials will move forward,” she said. “Any EUA request would have to include a strategy to ensure that the long-term safety and efficacy of a vaccine could be monitored. I see no evidence that either Pfizer or Moderna is not prepared to follow those regulations.”
Eventually, she added, the drug makers will have to seek full FDA approval to replace an EUA, which as its name signifies, is designed for public health emergencies. “The EUA is a tool to help us get the vaccine into circulation and have it start working as quickly as possible in the current health crisis,” she said. “But once the crisis is over, if the sponsors want to continue to market their vaccines, they have to go forward and get full approval.”
Medical ethicists, however, point out there may be ethical and practical dilemmas involved in continuing or initiating clinical trials once a vaccine has been approved for use even on an emergency basis.
In a commentary in Annals of Internal Medicine, Rafael Dal-Re, MD, PhD, Arthur L. Caplan, PhD, and two other ethicists stipulated that the pandemic requires early licensing and deployment of COVID-19 vaccines. Nevertheless, they noted, additional months of data are required to establish the long-term efficacy and safety of the vaccines. “Moreover, early deployment could interfere with the acquisition of long-term data,” both on these vaccines and on others coming through the pipeline, they wrote.
In countries where an approved vaccine is deployed, the ethicists noted, investigators must inform participants in an ongoing trial about the approved vaccine’s status and ask if they want to continue in the study. If enough participants decline, the trial might have to be terminated early. At that point, researchers may not have sufficient long-term data to identify late-term safety issues, determine how long efficacy lasts, determine whether waning immunity is associated with reduced levels of antibodies, or identify the level of neutralizing antibodies that correlates with immunity.
Moreover, they observed, long-term trials are especially important for vaccines that use mRNA technology, because less is known about them than about traditional kinds of vaccines.
The authors also pointed out that early licensing of any vaccine might make it harder to evaluate vaccines that haven’t yet been approved. “Once a vaccine is licensed, new placebo-controlled RCTs [randomized controlled trials] of other vaccines will not be acceptable ethically, and noninferiority RCTs will be the most likely alternative.
“The goal of noninferiority trials will be to demonstrate that the immune response (that is, neutralizing antibody titers or levels) of the candidate vaccine is not inferior to that of the approved vaccine within a prespecified margin, which the FDA has established as less than 10% for COVID-19 vaccines,” the authors noted.
More data with more study designs
Dial Hewlett Jr., MD, medical director for disease control services, Westchester County Department of Health, White Plains, N.Y., said in an interview that the ethicists raise important issues that have been discussed in other forums, including a recent webinar of the National Academy of Medicine.
“As the authors point out, once you have a vaccine that has been shown to be effective and safe, it’s no longer ethical to enroll people in placebo trials,” he said.
Therefore, he said, Pfizer and Moderna will undoubtedly offer their vaccines to the people in their studies’ placebo groups after the vaccines receive an EUA. Then they will follow everyone who has been vaccinated for 2 years to determine long-term safety. Efficacy will also continue to be measured as an adjunct of safety, he said.
With regard to the difficulty of reconsenting individuals to enter a new clinical trial after a vaccine has been approved, he said, “I’d agree that trying to get all the same participants to come into another study would be a challenge. You can, however, design studies that will allow you to obtain the same information. You will have a large number of people out there who haven’t been vaccinated, and you can do single-arm longitudinal studies and measure a number of things in the individuals who are enrolled in those studies,” he said.
“You can look at the immunologic markers, both antibody and T-cell. You can follow these individuals longitudinally to see if they do develop disease over a period of time. If they do, you can determine what their levels of response were,” he added. “So there are opportunities to design studies that would give you some of the same information, although it would not be in the same population that was in the randomized trials.”
For newer vaccines that have yet to be tested, he said, developers can compare “historical controls” from the trials of approved vaccines, i.e., data from the unvaccinated participants in those studies, with the data from inoculating people with the novel agents. The historical data can be sex- and age-matched, among other things, to individuals in the new trials. Moreover, because the study protocols have been harmonized for all trials under Operation Warp Speed, it doesn’t matter what kind of vaccine they’re testing, he said.
It may be necessary to do additional studies to find out how long immunity lasts after people have been vaccinated, Dr. Hewlett pointed out.
“You may have a different trial design. You don’t need a control arm to determine how long immunity lasts. You’re just comparing the patients who were vaccinated to nothing,” he said. “So you could have a single-arm trial on a group of people who consent to be immunized and followed. You can see what their antibody levels are and other surrogate markers, and you can see when they might develop disease, if they do. You’d need a large sample, but you can do that.”
Dr. Hewlett noted that additional studies will be required to determine whether the new vaccines stop transmission of the coronavirus or just prevent symptoms of COVID-19. Until it’s established that a vaccine halts transmission or the country achieves herd immunity, he said, “we’ll still have to wear masks and take other precautions, because a significant portion of people will still be at risk.”
‘A lot of redundancy’
Dr. Alexander emphasized that any safety or efficacy issues with the first COVID-19 vaccines must be identified before the vaccine is offered to a large portion of the U.S. population.
“While the data from the Pfizer and Moderna trials are said to be favorable, we at IDSA want to make sure that whatever vaccine comes to market is safe,” she said. “Having an unsafe vaccine on the market would be worse than no vaccine, because you’re compromising the public confidence. We have to make sure the public trusts the process and that sufficient data have been evaluated to ensure the vaccine is safe and efficacious.
“I believe the FDA is being very careful and thoughtful in [its] response,” Dr. Alexander said. “They realize how important it is to get a vaccine and save lives. While they’re doing things differently and moving much faster than before, they’re still trying to be thoughtful and reasonable. They don’t seem to be putting people at risk or circumventing the regulatory standards.”
Moreover, she pointed out, the FDA’s Vaccines and Related Biological Products Advisory Committee, which is expected to meet on Dec. 10, will review the trial data before the agency grants an EUA to Pfizer or Moderna. Then the FDA will post the data publicly.
The next step is for the Advisory Committee on Immunization Practices of the Centers for Disease Control and Prevention to look at the data and decide who in the United States should receive the vaccine first, she pointed out. And both Pfizer and Moderna have shown their data to advisory panels of outside experts.
“There’s a lot of redundancy, and a lot of people are looking at the data,” Dr. Alexander said. “So I don’t think we’re cutting corners to get it out there more quickly.”

Expanded indications likely for apremilast
Big changes are coming in the use of oral apremilast, currently approved for moderate to severe psoriasis and plaque psoriasis in adults, Bruce E. Strober, MD, PhD, predicted at MedscapeLive’s annual Las Vegas Dermatology Seminar, held virtually this year.
“We’ll have , meaning we can use this drug in patients in whom we typically think about using only topical therapies. Keep on the lookout: I think the mild to moderate indication may be coming next year, and that’s going to really shake up the whole landscape of psoriasis therapy,” said Dr. Strober, a dermatologist at Yale University in New Haven, Conn., and Central Connecticut Dermatology in Cromwell, Conn.
Mild or moderate psoriasis
Apremilast manufacturer Amgen has announced positive topline results from the phase 3 ADVANCE trial, a multicenter, placebo-controlled, double-blind, study of 595 patients with mild or moderate psoriasis as defined by an involved body surface area of 2%-15% and a Psoriasis Area and Severity Index score of 2-15. Participants were randomized to the approved dose of apremilast (Otezla) – 30 mg twice daily – or placebo for 16 weeks, followed by 16 weeks of open-label apremilast for all. The full study findings haven’t yet been published or presented at a medical conference, but Amgen announced that the results were positive for all primary and secondary endpoints, and the company plans to file a request with the Food and Drug Administration for an expanded indication for the oral agent.
Pediatric studies
A recently published phase 2, open-label, 1-year study of apremilast in 42 children and adolescents with moderate to severe plaque psoriasis demonstrated that weight-based dosing is the best approach in the pediatric population. The study, which serves as the template for coming phase 3 trials, showed that dosing apremilast at 20 mg twice daily in youths weighing not more than 35 kg and 30 mg twice daily in those who weighed more provided pharmacokinetic exposure similar to that achieved with apremilast at the standard adult dose of 30 mg twice daily. Most participants liked the taste of the tablet.
“My prediction is apremilast will have efficacy in children and teenagers comparable to what it has in adults, with a similar safety and adverse event profile,” Dr. Strober said.
Apremilast works by blocking phosphodiesterase type 4, thereby reducing cyclic AMP metabolism, with a resultant increase in cyclic AMP levels. Cyclic AMP is a regulator of inflammation. Boosting its level has the effect of decreasing tumor necrosis factor and other proinflammatory cytokines while increasing anti-inflammatory mediators, such as interleukin-10.
Dr. Strober characterized apremilast’s efficacy as “modest” by contemporary standards in adults with moderate to severe psoriasis, with week 16 PASI 75 rates of about 30% in randomized trials, compared with 5% in placebo-treated controls. He considers it a good option in patients with moderate disease who are needle phobic and in those averse to the inconvenience of laboratory monitoring. The drug is useful in treating psoriasis in especially challenging locations. Apremilast is specifically approved for scalp psoriasis, and Dr. Strober has anecdotally found it helpful in patients with palmoplantar psoriasis or genital psoriasis.
“Apremilast has tolerability issues: first and foremost diarrhea, nausea, and headache. Probably 15%-20% of patients have nausea or diarrhea ranging from mild to severe, and 1 in 20 have headache. You have to warn patients,” he said.
Roughly 1% of patients experience depressed mood. “I’ve seen it in a few patients. I definitely believe it’s real, so query patients about mood changes while taking apremilast,” the dermatologist advised.
One in 5 patients loses 5% of body weight during the first 6 months on apremilast, but there’s no additional weight loss thereafter. It’s wrong to characterize the oral agent as a weight-loss drug, though, since 80% of patients don’t lose weight, Dr. Strober noted.
Topical PDE-4 inhibitor shows promise
Separately at the Las Vegas meeting, Linda Stein Gold, MD, provided highlights of a phase 2b randomized trial of a topical cream formulation of an extremely potent PDE-4 inhibitor, roflumilast, in patients with chronic plaque psoriasis. This molecule is a couple hundred times more effective at inhibiting the PDE-4 receptor than either oral apremilast or topical crisaborole (Eucrisa). And as a once-daily topical agent with very little systemic absorption, roflumilast cream sidesteps the tolerability issues that accompany apremilast.
“Roflumilast is currently available as an oral formulation for treatment of [chronic obstructive pulmonary disease], so it has a fairly well-established safety profile,” noted Dr. Stein Gold, director of dermatology clinical research at the Henry Ford Health System in Detroit.
The 12-week, multicenter, phase 2b study sponsored by Arcutis Biotherapeutics included 331 patients with chronic plaque psoriasis who were randomized to once-daily 0.3% roflumilast cream, 0.15% roflumilast cream, or vehicle. Three-quarters of participants had baseline moderate disease.
A week-8 Investigator’s Global Assessment (IGA) score of 0 or 1, meaning clear skin or almost clear, plus at least a 2-grade improvement from baseline occurred in 32% of the high-dose roflumilast group, 25% of those on the 0.15% formulation, and 10% of controls. On the secondary endpoint of improvement in tough-to-treat intertriginous psoriasis, at week 12 an intertriginous IGA score of 0 or 1 plus at least a 2-point improvement from baseline was seen in 86% of the 0.3% roflumilast cream group, 50% on low-dose therapy, and 29% of controls. Moreover, the clinical improvements in IGA and itch kicked in quickly, with significant separation from placebo by week 2, Dr. Stein Gold noted.
The phase 3 program is now recruiting participants.
Dr. Strober and Dr. Stein Gold reported receiving research funding from and serving as consultants to Amgen and numerous other pharmaceutical companies.

New drug approved for relapsed/refractory neuroblastoma
The Food and Drug Administration has granted accelerated approval for naxitamab (Danyelza) to treat certain patients with neuroblastoma, based on response rates in two small trials.
Naxitamab is a humanized monoclonal antibody that targets GD2, a disialoganglioside highly expressed on neuroblastomas.
The FDA approved naxitamab for use in combination with granulocyte-macrophage colony-stimulating factor (GM-CSF) in adults and children aged 1 year and older who have relapsed or refractory, high-risk neuroblastoma in the bone or bone marrow that demonstrated a partial response, minor response, or stable disease to prior therapy.
Naxitamab was originally developed at Memorial Sloan Kettering Cancer Center in New York, and licensed exclusively to Y-mAbs Therapeutics. As a result of the licensing arrangement, MSKCC has institutional financial interests in the product, the company noted.
Study results
The accelerated approval of naxitamab was based on the overall response rate (ORR) and duration of response in two single-arm, open-label trials: Study 201 (NCT03363373) in 22 patients and Study 12-230 (NCT01757626) in 38 patients.
In both studies, patients received naxitamab at 3 mg/kg administered as an intravenous infusion on days 1, 3, and 5 of each 4-week cycle in combination with GM-CSF subcutaneously at 250 mcg/m2/day on days -4 to 0 and at 500 mcg/m2/day on days 1-5.
Some patients also received radiotherapy. At the investigator’s discretion, patients were permitted to receive preplanned radiation to the primary disease site in Study 201 and radiation to nontarget bony lesions or soft tissue disease in Study 12-230.
The ORR was 45% in Study 201 and 34% in Study 12-230. Responses were observed in the bone and/or bone marrow, the FDA noted.
Less than a third of patients had a duration of response that lasted 6 months or more – 30% of responders in Study 201 and 23% of responders in Study 12-230.
The FDA noted that continued approval of naxitamab may be contingent upon verification and description of clinical benefit in confirmatory trials.
The agency also noted that naxitamab was granted priority review, breakthrough therapy, and orphan drug designation. In addition, a priority review voucher was issued for the rare pediatric disease product application.
Boxed warning and adverse events
Naxitamab has a boxed warning about serious infusion-related reactions and neurotoxicity.
The product information notes that, in clinical studies, naxitamab has been shown to cause serious infusion reactions, including anaphylaxis, cardiac arrest, bronchospasm, stridor, and hypotension. Infusion reactions generally occurred within 24 hours of completing an infusion, most often within 30 minutes of initiation. Infusion reactions were most frequent during the first infusion in each cycle.
To mitigate these risks, Y-mAbs Therapeutics recommends premedication with an antihistamine, acetaminophen, an H2 antagonist, and corticosteroid, as well as close monitoring of patients during and for at least 2 hours after each infusion in a setting where cardiopulmonary resuscitation medication and equipment are available.
Based on its mechanism of action, naxitamab can cause severe pain, according to Y-mAbs Therapeutics. The company recommends premedication with gabapentin and, for example, oral oxycodone, and recommends treating break-through pain with intravenous hydromorphone or an equivalent intervention.
In addition, naxitamab may cause severe hypertension. The onset of hypertension may be delayed, so blood pressure should be monitored both during and after infusion.
The product insert also notes that one case of transverse myelitis (grade 3) and two cases of posterior reversible encephalopathy syndrome have been reported.
The most common adverse reactions (incidence ≥ 25% in either trial) were infusion-related reactions, pain, tachycardia, vomiting, cough, nausea, diarrhea, decreased appetite, hypertension, fatigue, erythema multiforme, peripheral neuropathy, urticaria, pyrexia, headache, injection site reaction, edema, anxiety, localized edema, and irritability.
The most common grade 3 or 4 laboratory abnormalities (≥ 5% in either trial) were decreased lymphocytes, decreased neutrophils, decreased hemoglobin, decreased platelet count, decreased potassium, increased alanine aminotransferase, decreased glucose, decreased calcium, decreased albumin, decreased sodium, and decreased phosphate.

To mitigate these risks, Y-mAbs Therapeutics recommends premedication with an antihistamine, acetaminophen, an H2 antagonist, and corticosteroid, as well as close monitoring of patients during and for at least 2 hours after each infusion in a setting where cardiopulmonary resuscitation medication and equipment are available.
Based on its mechanism of action, naxitamab can cause severe pain, according to Y-mAbs Therapeutics. The company recommends premedication with gabapentin and, for example, oral oxycodone, and recommends treating break-through pain with intravenous hydromorphone or an equivalent intervention.
In addition, naxitamab may cause severe hypertension. The onset of hypertension may be delayed, so blood pressure should be monitored both during and after infusion.
The product insert also notes that one case of transverse myelitis (grade 3) and two cases of posterior reversible encephalopathy syndrome have been reported.
The most common adverse reactions (incidence ≥ 25% in either trial) were infusion-related reactions, pain, tachycardia, vomiting, cough, nausea, diarrhea, decreased appetite, hypertension, fatigue, erythema multiforme, peripheral neuropathy, urticaria, pyrexia, headache, injection site reaction, edema, anxiety, localized edema, and irritability.
The most common grade 3 or 4 laboratory abnormalities (≥ 5% in either trial) were decreased lymphocytes, decreased neutrophils, decreased hemoglobin, decreased platelet count, decreased potassium, increased alanine aminotransferase, decreased glucose, decreased calcium, decreased albumin, decreased sodium, and decreased phosphate.

The Food and Drug Administration has granted accelerated approval for naxitamab (Danyelza) to treat certain patients with neuroblastoma, based on response rates in two small trials.
Naxitamab is a humanized monoclonal antibody that targets GD2, a disialoganglioside highly expressed on neuroblastomas.
The FDA approved naxitamab for use in combination with granulocyte-macrophage colony-stimulating factor (GM-CSF) in adults and children aged 1 year and older who have relapsed or refractory, high-risk neuroblastoma in the bone or bone marrow that demonstrated a partial response, minor response, or stable disease to prior therapy.
Naxitamab was originally developed at Memorial Sloan Kettering Cancer Center in New York, and licensed exclusively to Y-mAbs Therapeutics. As a result of the licensing arrangement, MSKCC has institutional financial interests in the product, the company noted.
Study results
The accelerated approval of naxitamab was based on the overall response rate (ORR) and duration of response in two single-arm, open-label trials: Study 201 (NCT03363373) in 22 patients and Study 12-230 (NCT01757626) in 38 patients.
In both studies, patients received naxitamab at 3 mg/kg administered as an intravenous infusion on days 1, 3, and 5 of each 4-week cycle in combination with GM-CSF subcutaneously at 250 mcg/m2/day on days -4 to 0 and at 500 mcg/m2/day on days 1-5.
Some patients also received radiotherapy. At the investigator’s discretion, patients were permitted to receive preplanned radiation to the primary disease site in Study 201 and radiation to nontarget bony lesions or soft tissue disease in Study 12-230.
The ORR was 45% in Study 201 and 34% in Study 12-230. Responses were observed in the bone and/or bone marrow, the FDA noted.
Less than a third of patients had a duration of response that lasted 6 months or more – 30% of responders in Study 201 and 23% of responders in Study 12-230.
The FDA noted that continued approval of naxitamab may be contingent upon verification and description of clinical benefit in confirmatory trials.
The agency also noted that naxitamab was granted priority review, breakthrough therapy, and orphan drug designation. In addition, a priority review voucher was issued for the rare pediatric disease product application.
Boxed warning and adverse events
Naxitamab has a boxed warning about serious infusion-related reactions and neurotoxicity.
The product information notes that, in clinical studies, naxitamab has been shown to cause serious infusion reactions, including anaphylaxis, cardiac arrest, bronchospasm, stridor, and hypotension. Infusion reactions generally occurred within 24 hours of completing an infusion, most often within 30 minutes of initiation. Infusion reactions were most frequent during the first infusion in each cycle.
To mitigate these risks, Y-mAbs Therapeutics recommends premedication with an antihistamine, acetaminophen, an H2 antagonist, and corticosteroid, as well as close monitoring of patients during and for at least 2 hours after each infusion in a setting where cardiopulmonary resuscitation medication and equipment are available.

CDC panel delves into priorities for COVID vaccine distribution
On Monday, members of an influential federal panel delved into the challenges ahead in deciding who will get the first doses of COVID-19 vaccines, including questions about which healthcare workers need those initial vaccinations the most.
The Advisory Committee on Immunization Practices (ACIP) of the Centers for Disease Control and Prevention (CDC) did not take any votes or seek to establish formal positions. Instead, the meeting served as a forum for experts to discuss the thorny issues ahead. The US Food and Drug Administration (FDA) could make a decision next month regarding clearance for the first COVID-19 vaccine.
An FDA advisory committee will meet December 10 to review the request for emergency use authorization (EUA) of a COVID-19 vaccine from Pfizer, in partnership with BioNTech. Moderna Inc said on November 16 that it expects to soon ask the FDA for an EUA of its rival COVID vaccine.
ACIP will face a two-part task after the FDA clears COVID-19 vaccines, said Nancy Messonnier, MD, director of the CDC’s National Center for Immunization and Respiratory Diseases. ACIP will need to first decide whether to recommend use of the vaccine and then address the “complicated and difficult” question of which groups should get the initial limited quantities.
“There aren’t any perfect decisions,” she told the ACIP members. “I know this is something that most of you didn’t anticipate doing, making these kinds of huge decisions in the midst of a pandemic.”
There has been considerable public discussion of prioritization of COVID-19 vaccines, including a set of recommendations offered by a special committee created by the National Academies of Sciences, Engineering and Medicine. In addition, CDC staff and members of ACIP outlined what they termed the “four ethical principles” meant to guide these decisions in a November 23 report in the agency’s Morbidity and Mortality Weekly Report. These four principles are to maximize benefits and minimize harms; promote justice; mitigate health inequities; and promote transparency.
But as the issuing of the first EUA nears, it falls to ACIP to move beyond endorsing broad goals. The panel will need to make decisions as to which groups will have to wait for COVID-19 vaccines.
ACIP members on Monday delved into these kinds of more detailed questions, using a proposed three-stage model as a discussion point.
In phase 1a of this model, healthcare workers and residents of long-term care facilities would be the first people to be vaccinated. Phase 1b would include those deemed essential workers, including police officers, firefighters, and those in education, transportation, food, and agriculture sectors. Phase 1c would include adults with high-risk medical conditions and those aged 65 years and older.
ACIP member Grace M. Lee, MD, MPH, of Stanford University, Stanford, California, questioned whether healthcare workers who are not seeing patients in person should wait to get the vaccines. There has been a marked rise in the use of telehealth during the pandemic, which has spared some clinicians from in-person COVID-19 patient visits in their practices.
“Close partnership with our public health colleagues will be critically important to make sure that we are not trying to vaccinate 100% of our healthcare workforce, if some proportion of our workforce can work from home,” Lee said.
ACIP member Pablo Sánchez, MD, of the Research Institute at Nationwide Children’s Hospital in Columbus, Ohio, concurred. Some clinicians, he noted, may have better access to personal protective equipment than others, he said.
“Unfortunately, not all healthcare workers are equal in terms of risk,” Sánchez said. “Within institutions, we’re going to have to prioritize which ones will get” the vaccine.
Clinicians may also make judgments about their own risk and need for early access to COVID-19 vaccinations, Sánchez said.
“I’m 66, and I’d rather give it to somebody much older and sicker than me,” he said.
Broader access
Fairly large populations will essentially be competing for limited doses of the first vaccines to reach the market.
The overlap is significant in the four priority groups put forward by CDC. The CDC staff estimated that about 21 million people would fall into the healthcare personnel category, which includes hospital staff, pharmacists, and those working in long-term care facilities. There are about 87 million people in the essential workers groups. More than 100 million adults in the United States, such as those with diabetes and cancers, fall into the high-risk medical conditions group. Another 53 million people are aged 65 and older.
Department of Health and Human Services Secretary Alex Azar on November 18 said the federal government expects to have about 40 million doses of these two vaccines by the end of December, which is enough to provide the two-dose regimen for about 20 million. If all goes as expected, Pfizer and Moderna will ramp up production.
Moderna has said that it expects by the end of this year to have approximately 20 million doses of its vaccine ready to ship in the United States and that it is on track to manufacture 500 million to 1 billion doses globally in 2021. Pfizer and BioNTech have said they expect to produce globally up to 50 million doses in 2020 and up to 1.3 billion doses by the end of 2021.
At the Monday meeting, several ACIP panelists stressed the need to ensure that essential workers get early doses of vaccines.
In many cases, these workers serve in jobs with significant public interaction and live in poor communities. They put themselves and their families at risk. Many of them lack the resources to take precautions available to those better able to isolate, said ACIP member Beth Bell, MD, MPH, of the University of Washington, Seattle, Washington.
“These essential workers are out there putting themselves at risk to allow the rest of us to socially distance,” she said. “Recognizing that not all of them may want to be vaccinated at this stage, we need to provide them with the opportunity early on in the process.”
In Bell’s view, the initial rollout of COVID-19 vaccines will send an important message about sharing this resource.
“If we’re serious about valuing equity, we need to have that baked in early on in the vaccination program,” she said.
Bell also said she was in favor of including people living in nursing homes in the initial wave of vaccinations. Concerns were raised about the frailty of this population.
“Given the mortality impact on the healthcare system from the number of nursing home residents that have been dying, I think on balance it makes sense to include them in phase 1a,” Bell said.
Other ACIP panelists said missteps with early vaccination of people in nursing homes could undermine faith in the treatments. Because of the ages and medical conditions of people in nursing homes, many of them may die after receiving the COVID-19 vaccine. Such deaths would not be associated with vaccine, but the medical community would not yet have evidence to disprove a connection.
There could be a backlash, with people falsely linking the death of a grandparent to the vaccine.
Fellow ACIP member Robert L. Atmar, MD, Baylor College of Medicine, Houston, Texas, was among those who had raised concerns about including people living in long-term care facilities in phase 1a. He said there are not yet enough data to judge the balance of benefits and harms of vaccination for this population.
The Pfizer and Moderna vaccines are “reactagenic,” meaning people may not feel well in the days after receiving the shots. The symptoms could lead to additional health evaluations of older people in nursing homes as clinicians try to figure out whether the patient’s reactions to the vaccine are caused by some condition or infection, Atmar said.
“Those of us who see these patients in the hospital recognize that there are often medical interventions that are done in the pursuit of a diagnosis, of a change in clinical status, that in and of themselves can lead to harm,” Atmar said.
Clinicians likely will have to encourage their patients of all ages to receive second doses of COVID-19 vaccines, despite the malaise they may provoke.
“We really need to make patients aware that this is not going to be a walk in the park. I mean, they’re going to know they had a vaccine, they’re probably not going to feel wonderful, but they’ve got to come back for that second dose,” said Sandra Adamson Fryhofer, MD, who represented the American Medical Association.
ACIP is expected to meet again to offer specific recommendations on the Pfizer and Moderna vaccines. ACIP’s recommendations trigger reimbursement processes, Azar said at a Tuesday press conference. ACIP’s work will inform decisions made by the federal government and governors about deploying shipments of COVID-19 vaccines, he said.
“At the end of the day, that is a decision, though, of the US government to make, which is where to recommend the prioritization,” Azar said. “It will be our nation’s governors in implementing the distribution plans to tell us” where to ship the vaccine.

FDA expands Xofluza indication to include postexposure flu prophylaxis
The US Food and Drug Administration (FDA) has expanded the indication for the antiviral baloxavir marboxil (Xofluza) to include postexposure prophylaxis of uncomplicated influenza in people aged 12 years and older.
“This expanded indication for Xofluza will provide an important option to help prevent influenza just in time for a flu season that is anticipated to be unlike any other because it will coincide with the coronavirus pandemic,” Debra Birnkrant, MD, director, Division of Antiviral Products, FDA Center for Drug Evaluation and Research, said in a press release.
In addition, Xofluza, which was previously available only in tablet form, is also now available as granules for mixing in water, the FDA said.
The agency first approved baloxavir marboxil in 2018 for the treatment of acute uncomplicated influenza in people aged 12 years or older who have been symptomatic for no more than 48 hours.
A year later, the FDA expanded the indication to include people at high risk of developing influenza-related complications, such as those with asthma, chronic lung disease, diabetes, heart disease, or morbid obesity, as well as adults aged 65 years or older.
The safety and efficacy of Xofluza for influenza postexposure prophylaxis is supported by a randomized, double-blind, controlled trial involving 607 people aged 12 years and older. After exposure to a person with influenza in their household, they received a single dose of Xofluza or placebo.
The primary endpoint was the proportion of individuals who became infected with influenza and presented with fever and at least one respiratory symptom from day 1 to day 10.
Of the 303 people who received Xofluza, 1% of individuals met these criteria, compared with 13% of those who received placebo.
The most common adverse effects of Xofluza include diarrhea, bronchitis, nausea, sinusitis, and headache.
Hypersensitivity, including anaphylaxis, can occur in patients taking Xofluza. The antiviral is contraindicated in people with a known hypersensitivity reaction to Xofluza.
Xofluza should not be coadministered with dairy products, calcium-fortified beverages, laxatives, antacids, or oral supplements containing calcium, iron, magnesium, selenium, aluminium, or zinc.
Full prescribing information is available online.

The agency first approved baloxavir marboxil in 2018 for the treatment of acute uncomplicated influenza in people aged 12 years or older who have been symptomatic for no more than 48 hours.
A year later, the FDA expanded the indication to include people at high risk of developing influenza-related complications, such as those with asthma, chronic lung disease, diabetes, heart disease, or morbid obesity, as well as adults aged 65 years or older.
The safety and efficacy of Xofluza for influenza postexposure prophylaxis is supported by a randomized, double-blind, controlled trial involving 607 people aged 12 years and older. After exposure to a person with influenza in their household, they received a single dose of Xofluza or placebo.
The primary endpoint was the proportion of individuals who became infected with influenza and presented with fever and at least one respiratory symptom from day 1 to day 10.
Of the 303 people who received Xofluza, 1% of individuals met these criteria, compared with 13% of those who received placebo.
The most common adverse effects of Xofluza include diarrhea, bronchitis, nausea, sinusitis, and headache.
Hypersensitivity, including anaphylaxis, can occur in patients taking Xofluza. The antiviral is contraindicated in people with a known hypersensitivity reaction to Xofluza.
Xofluza should not be coadministered with dairy products, calcium-fortified beverages, laxatives, antacids, or oral supplements containing calcium, iron, magnesium, selenium, aluminium, or zinc.

Metformin improves most outcomes for T2D during pregnancy
including reduced weight gain, reduced insulin doses, and fewer large-for-gestational-age babies, suggest the results of a randomized controlled trial.
However, the drug was associated with an increased risk of small-for-gestational-age babies, which poses the question as to risk versus benefit of metformin on the health of offspring.
“Better understanding of the short- and long-term implications of these effects on infants will be important to properly advise patients with type 2 diabetes contemplating use of metformin during pregnancy,” said lead author Denice S. Feig, MD, Mount Sinai Hospital, Toronto.
The research was presented at the Diabetes UK Professional Conference: Online Series on Nov. 17 and recently published in The Lancet Diabetes & Endocrinology.
Summing up, Dr. Feig said that, on balance, she would be inclined to give metformin to most pregnant women with type 2 diabetes, perhaps with the exception of those who may have risk factors for small-for-gestational-age babies; for example, women who’ve had intrauterine growth restriction, who are smokers, and have significant renal disease, or have a lower body mass index.
Increased prevalence of type 2 diabetes in pregnancy
Dr. Feig said that across the developed world there have been huge increases in the prevalence of type 2 diabetes in pregnancy in recent years.
Insulin is the standard treatment for the management of type 2 diabetes in pregnancy, but these women have marked insulin resistance that worsens in pregnancy, which means their insulin requirements increase, leading to weight gain, painful injections, high cost, and noncompliance.
So despite treatment with insulin, these women continue to face increased rates of adverse maternal and fetal outcomes.
And although metformin is increasingly being used in women with type 2 diabetes during pregnancy, there is a scarcity of data on the benefits and harms of metformin use on pregnancy outcomes in these women.
The MiTy trial was therefore undertaken to determine whether metformin could improve outcomes.
The team recruited 502 women from 29 sites in Canada and Australia who had type 2 diabetes prior to pregnancy or were diagnosed during pregnancy, before 20 weeks’ gestation. The women were randomized to metformin 1 g twice daily or placebo, in addition to their usual insulin regimen, at between 6 and 28 weeks’ gestation.
Type 2 diabetes was diagnosed prior to pregnancy in 83% of women in the metformin group and in 90% of those assigned to placebo. The mean hemoglobin A1c level at randomization was 47 mmol/mol (6.5%) in both groups.
The average maternal age at baseline was approximately 35 years and mean gestational age at randomization was 16 weeks. Mean prepregnancy BMI was approximately 34 kg/m2.
Of note, only 30% were of European ethnicity.
Less weight gain, lower A1c, less insulin needed with metformin
Dr. Feig reported that there was no significant difference between the treatment groups in terms of the proportion of women with the composite primary outcome of pregnancy loss, preterm birth, birth injury, respiratory distress, neonatal hypoglycemia, or admission to neonatal intensive care lasting more than 24 hours (P = 0.86).
However, women in the metformin group had significantly less overall weight gain during pregnancy than did those in the placebo group, at –1.8 kg (P < .0001).
They also had a significantly lower last A1c level in pregnancy, at 41 mmol/mol (5.9%) versus 43.2 mmol/mol (6.1%) in those given placebo (P = .015), and required fewer insulin doses, at 1.1 versus 1.5 units/kg/day (P < .0001), which translated to a reduction of almost 44 units/day.
Women given metformin were also less likely to require Cesarean section delivery, at 53.4% versus 62.7% in the placebo group (P = .03), although there was no difference between groups in terms of gestational hypertension or preeclampsia.
The most common adverse events were gastrointestinal complications, which occurred in 27.3% of women in the metformin group and 22.3% of those given placebo.
There were no significant differences between the metformin and placebo groups in rates of pregnancy loss (P = .81), preterm birth (P = .16), birth injury (P = .37), respiratory distress (P = .49), and congenital anomalies (P = .16).
Average birth weight lower with metformin
However, Dr. Feig showed that the average birth weight was lower for offspring of women given metformin than those assigned to placebo, at 3.2 kg (7.05 lb) versus 3.4 kg (7.4 lb) (P = .002).
Women given metformin were also less likely to have a baby with a birth weight of 4 kg (8.8 lb) or more, at 12.1% versus 19.2%, or a relative risk of 0.65 (P = .046), and a baby that was extremely large for gestational age, at 8.6% versus 14.8%, or a relative risk of 0.58 (P = .046).
But of concern, metformin was associated with an increased risk of small-for-gestational-age babies, at 12.9% versus 6.6% with placebo, or a relative risk of 1.96 (P = .03).
Dr. Feig suggested that this may be due to a direct effect of metformin “because as we know metformin inhibits the mTOR pathway,” which is a “primary nutrient sensor in the placenta” and could “attenuate nutrient flux and fetal growth.”
She said it is not clear whether the small-for-gestational-age babies were “healthy or unhealthy.”
To investigate further, the team has launched the MiTy Kids study, which will follow the offspring in the MiTy trial to determine whether metformin during pregnancy is associated with a reduction in adiposity and improvement in insulin resistance in the babies at 2 years of age.
Who should be given metformin?
During the discussion, Helen R. Murphy, MD, PhD, Norwich Medical School, University of East Anglia, England, asked whether Dr. Feig would recommend continuing metformin in pregnancy if it was started preconception for fertility issues rather than diabetes.
She replied: “If they don’t have diabetes and it’s simply for PCOS [polycystic ovary syndrome], then I have either stopped it as soon as they got pregnant or sometimes continued it through the first trimester, and then stopped.
“If the person has diabetes, however, I think given this work, for most people I would continue it,” she said.
The study was funded by the Canadian Institutes of Health Research, Lunenfeld-Tanenbaum Research Institute, and the University of Toronto. The authors have reported no relevant financial relationships.
