Experts debate wisdom of delaying second COVID-19 vaccine dose
A proposal to delay administration of the second dose of COVID-19 vaccines – suggested as a strategy to boost the number of people who get some degree of protection from a single immunization with the Pfizer/BioNTech or Moderna vaccines – is inciting a strong debate among clinicians and public health officials.
Opponents raise concerns about diverting from the two-dose schedule evaluated in clinical trials, including a lack of data on long-term protection from a single dose. They also suggest a longer interval between dosing could increase resistance of SARS-CoV-2 virus.
It is time to consider delaying the second dose, Robert M. Wachter, MD, at the University of California San Francisco, and Ashish Jha, MD, MPH, at Brown University in Providence, R.I., wrote in an opinion piece in The Washington Post Jan. 3.
The two experts state that supply constraints, distribution bottlenecks, and hundreds of thousands of new infections daily prompted them to change their stance on administering COVID-19 vaccines according to the two-dose clinical trial regimen. Furthermore, they cited a study in the New England Journal of Medicine that suggests 80%-90% efficacy for preventing SARS-CoV-2 infection following one dose of the Moderna vaccine.
Not everyone agrees one dose is a good idea. “Clinical trials with specific schedules for vaccine dosing – that’s the whole basis of the scientific evidence,” Maria Elena Bottazzi, PhD, associate dean of the National School of Tropical Medicine at Baylor College of Medicine in Houston, said in an interview.
After one dose “the immune system is learning, but it’s not ideal. That’s why you need the second dose,” Dr. Bottazzi said. “I appreciate the urgency and the anxiety ... but the data support [that] clinical efficacy requires two doses.”
Another proposed strategy to extend the current supply of COVID-19 vaccines to more Americans involves splitting the current dosage of the Moderna vaccine in half. Officials in the United States and the United Kingdom are reportedly considering this approach. In the United States, the Food and Drug Administration would have to approve any dosing change.
Agreeing to disagree
Dr. Wachter shared a link to his opinion piece on Twitter, stating that “We both came to this view because of the slow rollout & the new variant. But it’s a tough call and reasonable people will disagree.”
As predicted, the tweet elicited a number of strong opinions.
“There are no correct answers but there’s data deficiency, plenty of fodder and need for healthy, intellectual debate. That wouldn’t be occurring if there was an ample supply of vaccines,” Eric Topol, MD, director of the Scripps Translational Science Institute and editor-in-chief of Medscape, tweeted on Jan. 3.
“If the problem were with the supply of the vaccine, one might make an argument for focusing on 1st dose. But the problem is in distribution of the vaccine & giving actual doses,” John Grohol, PsyD, tweeted.
“Right now we don’t have a supply issue, we have a distribution issue,” Angela Shen, ScD, MPH, a research scientist in the Vaccine Education Center at Children’s Hospital of Philadelphia, said in an interview. Emergency use authorization for the Johnson & Johnson and other COVID-19 vaccines in development could further boost available supplies, she added.
“The clinical trials studied two doses,” Dr. Shen said. “We don’t have data that one dose is going to have lasting protection.”
Does new variant change equation?
Dr. Wachter and Dr. Jha, in their editorial, cited a quote from former boxing champion Mike Tyson: “Everybody has a plan until they’ve been punched in the mouth.” ‘Punches’ such as the new variant, the high number of cases and deaths in the United States, and other problems prompted them to advocate for the delayed dosing strategy.
“Appreciate the concern for the new variant – I think it’s worth noting that we’re punching ourselves in the mouth with the slow vaccine rollout, which is the first problem to solve,” Jake Quinton, MD, an internist at UCLA Health in Los Angeles, noted on Twitter.
Vaccine and public resistance raised
“I agree with the problem but not with the proposed solution, which is guesswork not based on data,” the Jan Grimm Lab at Memorial Sloan Kettering Cancer Center in New York responded to Dr. Wachter and Dr. Jha on Twitter. “There ARE data though that show that 1 shot alone did not elicit sufficient T-cell nor antibody response. This might also lead to mutations resistant to the vaccines. Dangerous!”
Other physicians took to Twitter to point out that changing the recommendations at this point could further erode public confidence in COVID-19 immunization. For example, Deirdre Habermehl, MD, wrote, “We’ve spent months telling the public the best route is to follow the science and now without data think a course correction based on a guesstimate is ok? Public confidence is low enough and the real issue is logistics at this point.”
Dr. Shen and Dr. Bottazzi have disclosed no relevant financial relationships.

New evidence shows that COVID-19 invades the brain
, new animal research suggests. Investigators injected spike 1 (S1), which is found on the tufts of the “red spikes” of the virus, into mice and found that it crossed the blood-brain barrier (BBB) and was taken up not only by brain regions and the brain space but also by other organs – specifically, the lungs, spleen, liver, and kidneys.
“We found that the S1 protein, which is the protein COVID-19 uses to ‘grab onto’ cells, crosses the BBB and is a good model of what the virus does when it enters the brain,” lead author William A. Banks, MD, professor of medicine, University of Washington, Seattle, said in an interview.
“When proteins such as the S1 protein become detached from the virus, they can enter the brain and cause mayhem, causing the brain to release cytokines, which, in turn, cause inflammation and subsequent neurotoxicity,” said Dr. Banks, associate chief of staff and a researcher at the Puget Sound Veterans Affairs Healthcare System.
The study was published online in Nature Neuroscience.
Neurologic symptoms
COVID-19 is associated with a variety of central nervous system symptoms, including the loss of taste and smell, headaches, confusion, stroke, and cerebral hemorrhage, the investigators noted.
Dr. Banks explained that SARS-CoV-2 may enter the brain by crossing the BBB, acting directly on the brain centers responsible for other body functions. The respiratory symptoms of COVID-19 may therefore result partly from the invasion of the areas of the brain responsible for respiratory functions, not only from the virus’ action at the site of the lungs.
The researchers set out to assess whether a particular viral protein – S1, which is a subunit of the viral spike protein – could cross the BBB or enter other organs when injected into mice. They found that, when intravenously injected S1 (I-S1) was cleared from the blood, tissues in multiple organs, including the lung, spleen, kidney, and liver, took it up.
Notably, uptake of I-S1 was higher in the liver, “suggesting that this protein is cleared from the blood predominantly by the liver,” Dr. Banks said. In addition, uptake by the lungs is “important, because that’s where many of the effects of the virus are,” he added.
The researchers found that I-S1 in the brains of the mice was “mostly degraded” 30 minutes following injection. “This indicates that I-S1 enters the BBB intact but is eventually degraded in the brain,” they wrote.
Moreover, by 30 minutes, more than half of the I-S1 proteins had crossed the capillary wall and had fully entered into the brain parenchymal and interstitial fluid spaces, as well as other regions.
More severe outcomes in men
The researchers then induced an inflammatory state in the mice through injection of lipopolysaccharide (LPS) and found that inflammation increased I-S1 uptake in both the brain and the lung (where uptake was increased by 101%). “These results show that inflammation could increase S1 toxicity for lung tissue by increasing its uptake,” the authors suggested. Moreover, inflammation also increased the entry of I-S1 into the brain, “likely due to BBB disruption.”
In human beings, male sex and APOE4 genotype are risk factors for both contracting COVID-19 and having a poor outcome, the authors noted. As a result, they examined I-S1 uptake in male and female mice that expressed human APOE3 or APOE4 (induced by a mouse ApoE promoter).
Multiple-comparison tests showed that among male mice that expressed human APOE3, the “fastest I-S1 uptake” was in the olfactory bulb, liver, and kidney. Female mice displayed increased APOE3 uptake in the spleen.
“This observation might relate to the increased susceptibility of men to more severe COVID-19 outcomes,” coauthor Jacob Raber, PhD, professor, departments of behavioral neuroscience, neurology, and radiation medicine, Oregon Health & Science University, Portland, said in a press release.
In addition to intravenous I-S1 injection, the researchers also investigated the effects of intranasal administration. They found that, although it also entered the brain, it did so at levels roughly 10 times lower than those induced by intravenous administration.
“Frightening tricks”
Dr. Banks said his laboratory has studied the BBB in conditions such as Alzheimer’s disease, obesity, diabetes, and HIV. “Our experience with viruses is that they do an incredible number of things and have a frightening number of tricks,” he said. In this case, “the virus is probably causing inflammation by releasing cytokines elsewhere in the body that get into the brain through the BBB.” Conversely, “the virus itself may enter the brain by crossing the BBB and directly cause brain cells to release their own cytokines,” he added.
An additional finding of the study is that, whatever the S1 protein does in the brain is a model for what the entire virus itself does, because these proteins often bring the viruses along with them, he added.
Dr. Banks said the clinical implications of the findings are that antibodies from those who have already had COVID-19 could potentially be directed against S1. Similarly, he added, so can COVID-19 vaccines, which induce production of S1.
“When an antibody locks onto something, it prevents it from crossing the BBB,” Dr. Banks noted.
Confirmatory findings
Commenting on the study, Howard E. Gendelman, MD, Margaret R. Larson Professor of Internal Medicine and Infectious Diseases and professor and chair of the department of pharmacology and experimental neuroscience, University of Nebraska, Omaha, said the study is confirmatory.
“What this paper highlights, and we have known for a long time, is that COVID-19 is a systemic, not only a respiratory, disease involving many organs and tissues and can yield not only pulmonary problems but also a whole host of cardiac, brain, and kidney problems,” he said.
“So the fact that these proteins are getting in [the brain] and are able to induce a reaction in the brain itself, and this is part of the complex progressive nature of COVID-19, is an important finding,” added Dr. Gendelman, director of the center for neurodegenerative disorders at the university. He was not involved with the study.
The study was supported by the Veterans Affairs Puget Sound Healthcare System and by grants from the National Institutes of Health. The authors and Dr. Gendelman have disclosed no relevant financial relationships.

FROM NATURE NEUROSCIENCE
Dealing with an anti-masker
Recently I got a referral from another office and skimmed through it, as I always do, to make sure it’s something I handle in my little practice.
Overall it seemed pretty straightforward, but on page 3 were multiple notes that the patient adamantly refused to wear a mask to visits, or took one off as soon as she got back to an exam room and refused to put it back on. She also insisted on in-person, not video, visits. Staff members had documented that she told them masks were “stupid and worthless” and called people who insisted on them “idiots.”
I looked at the notes for a minute, then flagged them to indicate she is someone who shouldn’t be scheduled if she calls, forwarded them to my secretary, and moved on to my next patient.
Some might say this is discrimination, but I disagree. Although studies vary on the degree of efficacy, the overall data show that masks help prevent the wearer from spreading COVID-19 to others, to a lesser degree protect you from catching it from others, and are safe to use.
So The data on COVID-19 spreading through asymptomatic people is pretty solid, so those who say “I feel fine, so I don’t need to wear a mask” are only endangering others.
Certainly, people have the right to refuse masks, but currently the laws in my area require them in public, and I definitely require them in my little practice. I’m not calling the police if someone doesn’t wear one, but I’m not going to see them in my practice, either.
Like all other doctors, health care workers, and patients, I’m as susceptible to infectious disease as everyone else. If I’m sick, I can’t take care of others.
I’m not refusing to see the sick—far from it—but if I’m going to try to help you get better, then you should be willing to wear a mask to help protect me, too.

Recently I got a referral from another office and skimmed through it, as I always do, to make sure it’s something I handle in my little practice.
Overall it seemed pretty straightforward, but on page 3 were multiple notes that the patient adamantly refused to wear a mask to visits, or took one off as soon as she got back to an exam room and refused to put it back on. She also insisted on in-person, not video, visits. Staff members had documented that she told them masks were “stupid and worthless” and called people who insisted on them “idiots.”
I looked at the notes for a minute, then flagged them to indicate she is someone who shouldn’t be scheduled if she calls, forwarded them to my secretary, and moved on to my next patient.
Some might say this is discrimination, but I disagree. Although studies vary on the degree of efficacy, the overall data show that masks help prevent the wearer from spreading COVID-19 to others, to a lesser degree protect you from catching it from others, and are safe to use.
So The data on COVID-19 spreading through asymptomatic people is pretty solid, so those who say “I feel fine, so I don’t need to wear a mask” are only endangering others.
Certainly, people have the right to refuse masks, but currently the laws in my area require them in public, and I definitely require them in my little practice. I’m not calling the police if someone doesn’t wear one, but I’m not going to see them in my practice, either.
Like all other doctors, health care workers, and patients, I’m as susceptible to infectious disease as everyone else. If I’m sick, I can’t take care of others.

COVID-19 vaccine rollout faces delays
If the current pace of vaccination continues, “it’s going to take years, not months, to vaccinate the American people,” President-elect Joe Biden said during a briefing Dec. 29.
In fact, at the current rate, it would take nearly 10 years to vaccinate enough Americans to bring the pandemic under control, according to NBC News. To reach 80% of the country by late June, 3 million people would need to receive a COVID-19 vaccine each day.
“As I long feared and warned, the effort to distribute and administer the vaccine is not progressing as it should,” Mr. Biden said, reemphasizing his pledge to get 100 million doses to Americans during his first 100 days as president.
So far, 11.4 million doses have been distributed and 2.1 million people have received a vaccine, according to the Centers for Disease Control and Prevention. Most states have administered a fraction of the doses they’ve received, according to data compiled by The New York Times.
Federal officials have said there’s an “expected lag” between delivery of doses, shots going into arms, and the data being reported to the CDC, according to CNN. The Food and Drug Administration must assess each shipment for quality control, which has slowed down distribution, and the CDC data are just now beginning to include the Moderna vaccine, which the FDA authorized for emergency use on Dec. 18.
The 2.1 million number is “an underestimate,” Brett Giroir, MD, the assistant secretary of the U.S. Department of Health & Human Services, told NBC News Dec. 29. At the same time, the U.S. won’t meet the goal of vaccinating 20 million people in the next few days, he said.
Another 30 million doses will go out in January, Dr. Giroir said, followed by 50 million in February.
Some vaccine experts have said they’re not surprised by the speed of vaccine distribution.
“It had to go this way,” Paul Offit, MD, a professor of pediatrics at Children’s Hospital of Philadelphia, told STAT. “We had to trip and fall and stumble and figure this out.”
To speed up distribution in 2021, the federal government will need to help states, Mr. Biden said Dec. 29. He plans to use the Defense Authorization Act to ramp up production of vaccine supplies. Even still, the process will take months, he said.

CDC issues COVID-19 vaccine guidance for underlying conditions
The Centers for Disease Control and Prevention has issued updated guidance for people with underlying medical conditions who are considering getting the coronavirus vaccine.
“Adults of any age with certain underlying medical conditions are at increased risk for severe illness from the virus that causes COVID-19,” the CDC said in the guidance, posted on Dec. 26. “mRNA COVID-19 vaccines may be administered to people with underlying medical conditions provided they have not had a severe allergic reaction to any of the ingredients in the vaccine.”
Both the Pfizer and Moderna vaccines use mRNA, or messenger RNA.
The CDC guidance had specific information for people with HIV, weakened immune systems, and autoimmune conditions such as Guillain-Barré syndrome (GBS) and Bell’s palsy who are thinking of getting the vaccine.
People with HIV and weakened immune systems “may receive a COVID-19 vaccine. However, they should be aware of the limited safety data,” the CDC said.
There’s no information available yet about the safety of the vaccines for people with weakened immune systems. People with HIV were included in clinical trials, but “safety data specific to this group are not yet available at this time,” the CDC said.
Cases of Bell’s palsy, a temporary facial paralysis, were reported in people receiving the Pfizer and Moderna vaccines in clinical trials, the Food and Drug Administration said Dec. 17.
But the new CDC guidance said that the FDA “does not consider these to be above the rate expected in the general population. They have not concluded these cases were caused by vaccination. Therefore, persons who have previously had Bell’s palsy may receive an mRNA COVID-19 vaccine.”
Researchers have determined the vaccines are safe for people with GBS, a rare autoimmune disorder in which the body’s immune system attacks nerves just as they leave the spinal cord, the CDC said.
“To date, no cases of GBS have been reported following vaccination among participants in the mRNA COVID-19 vaccine clinical trials,” the CDC guidance said. “With few exceptions, the independent Advisory Committee on Immunization Practices general best practice guidelines for immunization do not include a history of GBS as a precaution to vaccination with other vaccines.”
For months, the CDC and other health authorities have said that people with certain medical conditions are at an increased risk of developing severe cases of COVID-19.

New resilience center targets traumatized health care workers
A physician assistant participating in a virtual workshop began to cry, confessing that she felt overwhelmed with guilt because New Yorkers were hailing her as a frontline hero in the pandemic. That was when Joe Ciavarro knew he was in the right place.
“She was saying all the things I could not verbalize because I, too, didn’t feel like I deserved all this praise and thousands of people cheering for us every evening when people were losing jobs, didn’t have money for food, and their loved ones were dying without family at their side,” says Mr. Ciavarro, a PA at Mount Sinai Medical Center in New York.
Mr. Ciavarro, who also manages 170 other PAs on two of Mount Sinai’s campuses in Manhattan, has been on the front lines since COVID-19 first hit; he lost a colleague and friend to suicide in September.
The mental anguish from his job prompted him to sign up for the resilience workshop offered by Mount Sinai’s Center for Stress, Resilience, and Personal Growth. The center – the first of its kind in North America – was launched in June to help health care workers like him cope with the intense psychological pressures they were facing. The weekly workshops became a safe place where Mr. Ciavarro and other staff members could share their darkest fears and learn ways to help them deal with their situation.
“It’s been grueling but we learned how to take care of ourselves so we can take care of our patients,” said Mr. Ciavarro. “This has become like a guided group therapy session on ways to manage and develop resilience. And I feel like my emotions are validated, knowing that others feel the same way.”
Caring for their own
Medical professionals treating patients with COVID-19 are in similar predicaments, and the psychological fallout is enormous: They’re exhausted by the seemingly never-ending patient load and staffing shortages, and haunted by fears for their own safety and that of their families. Studies in China, Canada, and Italy have revealed that a significant number of doctors and nurses in the early days of the pandemic experienced high levels of distress, depression, anxiety, nightmares, and insomnia.
after witnessing the deaths of so many patients who were alone, without family.
But the resilience workshop that Mr. Ciavarro attended offers some hope and is part of a multifaceted program that aims to be a model for other institutions and communities. The Mount Sinai health system already had some programs in place, including centers for 9/11 responders, for spirituality and health, and a wellness program to aid burned-out doctors. But the leadership at Mount Sinai, which includes psychiatrist Dennis Charney, MD, dean of the medical school and a leading expert on PTSD, knew early in the pandemic that emotional and psychological distress would plague health care workers, according to Deborah Marin, MD, director of the new center.
“We decided to quickly put in place a program that we could do virtually, with workshops and apps, that would give access to several services above and beyond what was already going on,” says Dr. Marin, a professor of psychiatry at the Icahn School of Medicine at Mount Sinai, New York, who also directs their center for spirituality and health.
The key components include a comprehensive screening tool that helps doctors at the center identify which potential participants are most at risk. Participants build personal inventories that detail the intensity of work-related exposures, personal or family stressors that have arisen because of the pandemic, or any mental health conditions or substance abuse problems that may make staff members more vulnerable.
The weekly workshops led by trained staff are designed to give participants the tools to foster resilience and process their experiences. Online apps provide feedback on their progress and engage them with video and other resources around meditation, relaxation, and resilience techniques.
In addition, all 40,000 members of the Mount Sinai staff are eligible for up to 14 one-on-one sessions with psychologists and psychiatrists who specialize in treating trauma.
“That’s highly unusual – to offer this at no cost to everyone,” said Dr. Marin. “We also have a treatment service that is specifically focused on behavioral health care, so people can learn better coping strategies, and we also have social workers to provide coaching.”
While the center doesn’t have specific numbers on how many nurses, physicians, and other staff have participated in treatment, they have trained over 70 peer leaders for their five workshops that home in on the most important factors of resilience.
“We’ve gotten enthusiastic responses from PAs and nurses,” said Craig Katz, MD, an expert in disaster psychiatry at Mount Sinai and a workshop moderator. Physicians have been slower to get on board. “Doctors are a tough nut to crack – it’s largely a culture where they may burn out but don’t want to talk about it. And asking for help is a hard transition for physicians to make.”
How to protect in midst of trauma
In formulating the program’s platform, Mount Sinai experts drew upon their extensive experience aiding 9/11 responders at the World Trade Center (WTC), as well as their system-wide wellness program that aids demoralized and burned-out physicians. While the reach of the pandemic is much broader than 9/11, experts see some commonalities in conditions that emerge after traumatic events, and they also discovered what can help.
“We learned from our WTC experience about what are protective factors – what are the social supports that buffer against depression, anxiety, and PTSD,” said Jonathan DePierro, PhD, clinical director of CSRPG and a psychologist at the Mount Sinai WTC Mental Health Program. “We also learned that people who have more prolonged exposures are at greater risk of developing mental health difficulties.”
The program itself reflects these lessons – and that’s why it’s open to all employees, not just medical professionals. Housekeepers, security staffers, even construction workers are also dealing with their lives being in danger. “That wasn’t in their job description,” said Dr. DePierro. “These people tend to have fewer social and economic resources, make less money and have fewer structural supports, which makes them even more vulnerable.”
Dr. Charney’s strategies on building resilience became a bible of sorts for the workshops, according to Dr. Katz, who authored the training curriculum. Sessions deal with how to build up reservoirs of realistic optimism, keep gratitude journals, find spiritual meaning in their lives, maintain physical wellness and create networks of social support. The workshops are meant to help participants create action plans, to reach out for support in their social networks, and keep the focus on the positives.
The goal is to give demoralized health care workers a renewed sense of competence. “The resilience workshop is a launching point to get people to show up and talk,” said Dr. Katz. “And if we do that, we’ve accomplished a lot just getting people in the door.”
The center will also have a research component to identify what works and what doesn’t so their platform can provide a template for other institutions; Dr. Marin said they’ve gotten inquiries about the program from major hospital systems in Michigan and California. They’ll also conduct longitudinal research to determine what lingering problems persist among healthcare workers over time.
Since the center opened its virtual doors, the curriculum has also been altered in response to feedback from the support staff, many of whom live in the community that surrounds Mount Sinai in northern Manhattan, which is largely lower-income Latinx and Black individuals. Workshop materials have been translated into Spanish and now feature people who reflect a more diverse set of experiences.
“Many of our employees and the population we serve identify as non-White so we’ve been doing outreach with a lot of the local unions,” said Dr. Marin. “Our next step is to take what we’re doing and work with local community organizations.”

“We decided to quickly put in place a program that we could do virtually, with workshops and apps, that would give access to several services above and beyond what was already going on,” says Dr. Marin, a professor of psychiatry at the Icahn School of Medicine at Mount Sinai, New York, who also directs their center for spirituality and health.
The key components include a comprehensive screening tool that helps doctors at the center identify which potential participants are most at risk. Participants build personal inventories that detail the intensity of work-related exposures, personal or family stressors that have arisen because of the pandemic, or any mental health conditions or substance abuse problems that may make staff members more vulnerable.
The weekly workshops led by trained staff are designed to give participants the tools to foster resilience and process their experiences. Online apps provide feedback on their progress and engage them with video and other resources around meditation, relaxation, and resilience techniques.
In addition, all 40,000 members of the Mount Sinai staff are eligible for up to 14 one-on-one sessions with psychologists and psychiatrists who specialize in treating trauma.
“That’s highly unusual – to offer this at no cost to everyone,” said Dr. Marin. “We also have a treatment service that is specifically focused on behavioral health care, so people can learn better coping strategies, and we also have social workers to provide coaching.”
While the center doesn’t have specific numbers on how many nurses, physicians, and other staff have participated in treatment, they have trained over 70 peer leaders for their five workshops that home in on the most important factors of resilience.
“We’ve gotten enthusiastic responses from PAs and nurses,” said Craig Katz, MD, an expert in disaster psychiatry at Mount Sinai and a workshop moderator. Physicians have been slower to get on board. “Doctors are a tough nut to crack – it’s largely a culture where they may burn out but don’t want to talk about it. And asking for help is a hard transition for physicians to make.”
How to protect in midst of trauma
In formulating the program’s platform, Mount Sinai experts drew upon their extensive experience aiding 9/11 responders at the World Trade Center (WTC), as well as their system-wide wellness program that aids demoralized and burned-out physicians. While the reach of the pandemic is much broader than 9/11, experts see some commonalities in conditions that emerge after traumatic events, and they also discovered what can help.
“We learned from our WTC experience about what are protective factors – what are the social supports that buffer against depression, anxiety, and PTSD,” said Jonathan DePierro, PhD, clinical director of CSRPG and a psychologist at the Mount Sinai WTC Mental Health Program. “We also learned that people who have more prolonged exposures are at greater risk of developing mental health difficulties.”
The program itself reflects these lessons – and that’s why it’s open to all employees, not just medical professionals. Housekeepers, security staffers, even construction workers are also dealing with their lives being in danger. “That wasn’t in their job description,” said Dr. DePierro. “These people tend to have fewer social and economic resources, make less money and have fewer structural supports, which makes them even more vulnerable.”
Dr. Charney’s strategies on building resilience became a bible of sorts for the workshops, according to Dr. Katz, who authored the training curriculum. Sessions deal with how to build up reservoirs of realistic optimism, keep gratitude journals, find spiritual meaning in their lives, maintain physical wellness and create networks of social support. The workshops are meant to help participants create action plans, to reach out for support in their social networks, and keep the focus on the positives.
The goal is to give demoralized health care workers a renewed sense of competence. “The resilience workshop is a launching point to get people to show up and talk,” said Dr. Katz. “And if we do that, we’ve accomplished a lot just getting people in the door.”
The center will also have a research component to identify what works and what doesn’t so their platform can provide a template for other institutions; Dr. Marin said they’ve gotten inquiries about the program from major hospital systems in Michigan and California. They’ll also conduct longitudinal research to determine what lingering problems persist among healthcare workers over time.
Since the center opened its virtual doors, the curriculum has also been altered in response to feedback from the support staff, many of whom live in the community that surrounds Mount Sinai in northern Manhattan, which is largely lower-income Latinx and Black individuals. Workshop materials have been translated into Spanish and now feature people who reflect a more diverse set of experiences.
“Many of our employees and the population we serve identify as non-White so we’ve been doing outreach with a lot of the local unions,” said Dr. Marin. “Our next step is to take what we’re doing and work with local community organizations.”

Moderna’s COVID-19 vaccine deemed ‘highly effective,’ but further studies needed
The Food and Drug Administration’s Vaccines and Related Biological Products Advisory Committee (VRBPAC) evaluated
The panel acknowledged that further studies will be required post issuance of an Emergency Use Authorization (EUA) to collect additional data on the safety and effectiveness of the vaccine. A briefing document released by the FDA on Dec. 17, 2020, summarized interim results and included recommendations from VRBPAC on use of Moderna’s mRNA-1273 COVID-19 vaccine.
“On November 30, 2020, ModernaTX (the Sponsor) submitted an EUA request to FDA for an investigational COVID-19 vaccine (mRNA-1273) intended to prevent COVID-19,” the committee wrote.
The mRNA-1273 vaccine trial
Among 30,351 individuals aged 18 years and older, the efficacy, safety, and immunogenicity of the mRNA-1273 vaccine candidate was evaluated in a randomized, stratified, observer-blind, placebo-controlled phase 3 study. Participants were randomly assigned (1:1) to receive two injections of either 100 mcg of mRNA-1273 (n = 15,181) or saline placebo (n = 15,170) administered intramuscularly on day 1 and day 29.
The primary efficacy endpoint was efficacy of mRNA-1273 against PCR-confirmed COVID-19 with onset at least 14 days following the second dose. The primary safety endpoint was to characterize the safety of the vaccine following one or two doses.
Efficacy
Among 27,817 subjects included in the first interim analysis (data cutoff: Nov. 7, 2020), 5 cases of COVID-19 with onset at least 14 days after the second dose occurred among vaccine recipients and 90 case occurred among placebo recipients, corresponding to 94.5% vaccine efficacy (95% confidence interval, 86.5%-97.8%).
“Subgroup analyses of the primary efficacy endpoint showed similar efficacy point estimates across age groups, genders, racial and ethnic groups, and participants with medical comorbidities associated with high risk of severe COVID-19,” they reported.
Data from the final scheduled analysis of the primary efficacy endpoint (data cutoff: Nov. 21, 2020; median follow-up of >2 months after dose 2), demonstrated 94.1% vaccine efficacy (95% confidence interval, 89.3%-96.8%), corresponding to 11 cases of COVID-19 in the vaccine group and 185 cases in the placebo group.
When stratified by age, the vaccine efficacy was 95.6% (95% CI, 90.6%-97.9%) for individuals 18-64 years of age and 86.4% (95% CI, 61.4%-95.5%) for those 65 years of age or older.
In addition, results from secondary analyses indicated benefit for mRNA-1273 in preventing severe COVID-19 cases, COVID-19 in those with prior SARS-CoV-2 infection, and infection after the first dose, but these data were not conclusive.
Safety
Among 30,350 subjects included in the first interim analysis (data cutoff: Nov. 11, 2020; median follow-up of 7 weeks post second dose), no specific safety concerns were observed that would prevent issuance of an EUA.
Additional safety data (data cutoff: Nov. 25, 2020; median follow-up of 9 weeks post second dose) were provided on Dec. 7, 2020, but did not change the conclusions from the first interim analysis.
The most common vaccine-related adverse reactions were injection site pain (91.6%), fatigue (68.5%), headache (63.0%), muscle pain (59.6%), joint pain (44.8%), and chills (43.4%).
“The frequency of serious adverse events (SAEs) was low (1.0% in the mRNA-1273 arm and 1.0% in the placebo arm), without meaningful imbalances between study arms,” they reported.
Myocardial infarction (0.03%), nephrolithiasis (0.02%), and cholecystitis (0.02%) were the most common SAEs that were numerically greater in the vaccine arm than the placebo arm; however, the small number of cases does not infer a casual relationship.
“The 2-dose vaccination regimen was highly effective in preventing PCR-confirmed COVID-19 occurring at least 14 days after receipt of the second dose,” the committee wrote. “[However], it is critical to continue to gather data about the vaccine even after it is made available under EUA.”
The associated phase 3 study was sponsored by ModernaTX.

Call to arms: vaccinating the health workforce of 21 million strong
As the first American health care workers rolled up their sleeves for a COVID-19 vaccine, the images were instantly frozen in history, marking the triumph of scientific know-how and ingenuity. Cameras captured the first trucks pulling out of a warehouse in Portage, Mich., to the applause of workers and area residents. A day later, Boston Medical Center employees – some dressed in scrubs and wearing masks, face shields, and protective gowns – literally danced on the sidewalk when doses arrived. Some have photographed themselves getting the vaccine and posted it on social media, tagging it #MyCOVIDVax.
But the real story of the debut of COVID-19 vaccination is more methodical than monumental, a celebration of teamwork rather than of conquest. As hospitals waited for their first allotment, they reviewed their carefully drafted plans. They relied on each other, reaching across the usual divisions of competition and working collaboratively to share the limited supply. Their priority lists for the first vaccinations included environmental services workers who clean patient rooms and the critical care physicians who work to save lives.
“Health care workers have pulled together throughout this pandemic,” said Melanie Swift, MD, cochair of the COVID-19 Vaccine Allocation and Distribution Work Group at Mayo Clinic in Rochester, Minn. “We’ve gone through the darkest of years relying so heavily on each other,” she said. “Now we’re pulling together to get out of it.”
Still, a rollout of this magnitude has hitches. Stanford issued an apology Dec. 18 after its medical residents protested a vaccine distribution plan that left out nearly all of its residents and fellows, many of whom regularly treat patients with COVID-19.
There have already been more than 287,000 COVID-19 cases and 953 deaths among health care workers, according to the Centers for Disease Control and Prevention. In its guidance, the agency pointed out that the “continued protection of them at work, at home, and in the community remains a national priority.” That means vaccinating a workforce of about 21 million people, often the largest group of employees in a community.
“It collectively takes all of us to vaccinate our teams to maintain that stability in our health care infrastructure across the metro Atlanta area,” Christy Norman, PharmD, vice president of pharmacy services at Emory Healthcare, told reporters in a briefing as the health system awaited its first delivery.
Don’t waste a dose
One overriding imperative prevails: Hospitals don’t want to waste any doses. The storage requirements of the Pfizer vaccine make that tricky.
Once vials are removed from the pizza-box-shaped containers in ultracold storage and placed in a refrigerator, they must be used within 5 days. Thawed five-dose vials must be brought to room temperature before they are diluted, and they can remain at room temperature for no more than 2 hours. Once they are diluted with 1.8 mL of a 0.9% sodium chloride injection, the vials must be used within 6 hours.
COVID-19 precautions require employees to stay physically distant while they wait their turn for vaccination, which means the process can’t mirror typical large-scale flu immunization programs.
To prioritize groups, the vaccination planners at Mayo conducted a thorough risk stratification, considering each employee’s duties. Do they work in a dedicated COVID-19 unit? Do they handle lab tests or collect swabs? Do they work in the ICU or emergency department?
“We have applied some principles to make sure that as we roll it out, we prioritize people who are at greatest risk of ongoing exposure and who are really critical to maintaining the COVID response and other essential health services,” said Dr. Swift, associate medical director of Mayo’s occupational health service.
Mayo employees who are eligible for the first doses can sign up for appointments through the medical record system. If it seems likely that some doses will be left over at the end of the vaccination period – perhaps because of missed appointments – supervisors in high-risk areas can refer other health care workers. Mayo gave its first vaccines on Dec. 18, but the vaccination program began in earnest the following week. With the pleasant surprise that each five-dose vial actually provides six doses, 474 vials will allow for the vaccination of 2,844 employees in the top-priority group. “It’s going to expand each week or few days as we get more and more vaccine,” Dr. Swift said.
Sharing vials with small rural hospitals
Minnesota is using a hub-and-spoke system to give small rural hospitals access to the Pfizer vaccine, even though they lack ultracold storage and can’t use a minimum order of 975 doses. Large hospitals, acting as hubs, are sharing their orders. (The minimum order for Moderna is 100 doses.)
In south-central Minnesota, for example, two hub hospitals each have six spoke hospitals. Five of the 14 hospitals are independent, and the rest are part of large hospital systems, but affiliation doesn’t matter, said Eric Weller, regional health care preparedness coordinator for the South Central Healthcare Coalition. “We are all working together. It doesn’t matter what system you’re from,” he said. “We’re working for the good of the community.”
Each hospital designed a process to provide vaccine education, prioritize groups, allocate appointments, register people for vaccination, obtain signed consent forms, administer vaccines in a COVID-safe way, and provide follow-up appointments for the second dose. “We’re using some of the lessons we learned during H1N1,” said Mr. Weller, referring to immunization during the 2009 influenza pandemic. “The difference is that during H1N1, you could have lines of people.”
Coordinating the appointments will be more important than ever. “One of the vaccination strategies is to get people in groups of five, so you use one vial on those five people and don’t waste it,” he said.
Logistics are somewhat different for the Moderna vaccine, which will come in 10-dose vials that can be refrigerated for up to 30 days.
Both vaccines may produce mild flulike symptoms, such as fatigue, headache, or muscle pain, particularly after the second dose. That’s a sign that the immune system is reacting to the vaccine, but it’s also another consideration in the vaccination plans, because health care workers might take a day or two off work. “We’re not going to vaccinate a whole department at one time. It will be staggered,” said Kevin Smith, MD, medical director of the occupational medicine program at ProMedica, a health care system based in Toledo, Ohio.
Dr. Smith said he plans to encourage employees to use V-Safe, an app created by the CDC to track adverse effects in people who receive the vaccine. He pointed out that a day or two of achiness will be better than coping with the symptoms of COVID-19. Some employees who recovered from the infection still feel fatigued or haven’t regained their sense of taste and smell. “We are still monitoring quite a few employees to make sure they get back to 100%,” he said.
Hope for ending the pandemic
Public health officials have worried about vaccine hesitancy, even among health care workers, but so far, that concern seems overshadowed by enthusiasm. Dr. Smith said his department has been fielding calls from employees who want to know when they will be able to get the vaccine. “I think everyone feels relief,” he said. “We’re at the beginning of the end.”
At Mayo, Dr. Swift is surveying staff to gauge the willingness to get the vaccine, but she already senses excitement among employees. “No doubt there are still people who are hesitant, but I’m feeling a shift,” she said. “I’m feeling this momentum building of health care workers coming on board and wanting to take this vaccine, which is good, because they will set an example for their patients.”
For Colleen Kelley, MD, an infectious disease physician at Emory University in Atlanta who was principal investigator for an Emory-affiliated Moderna clinical trial site, it has been an emotional time. “Things were looking very bleak and dark for a time, and then we started to get these efficacy results that were greater than anyone imagined,” she said.
Dr. Kelley spends time talking to journalists and educating physician colleagues and hospital employees about how the vaccine was developed so quickly and how it works. “Everyone asks me, ‘Should I get it? Are you going to get it?’ My answer is ‘yes’ and ‘yes,’ “ she said. “I am 1,000% confident that the benefits of widespread vaccination outweigh the risks of continued COVID and a continued pandemic.”

He pointed out that a day or two of achiness will be better than coping with the symptoms of COVID-19. Some employees who recovered from the infection still feel fatigued or haven’t regained their sense of taste and smell. “We are still monitoring quite a few employees to make sure they get back to 100%,” he said.
Hope for ending the pandemic
Public health officials have worried about vaccine hesitancy, even among health care workers, but so far, that concern seems overshadowed by enthusiasm. Dr. Smith said his department has been fielding calls from employees who want to know when they will be able to get the vaccine. “I think everyone feels relief,” he said. “We’re at the beginning of the end.”
At Mayo, Dr. Swift is surveying staff to gauge the willingness to get the vaccine, but she already senses excitement among employees. “No doubt there are still people who are hesitant, but I’m feeling a shift,” she said. “I’m feeling this momentum building of health care workers coming on board and wanting to take this vaccine, which is good, because they will set an example for their patients.”
For Colleen Kelley, MD, an infectious disease physician at Emory University in Atlanta who was principal investigator for an Emory-affiliated Moderna clinical trial site, it has been an emotional time. “Things were looking very bleak and dark for a time, and then we started to get these efficacy results that were greater than anyone imagined,” she said.
Dr. Kelley spends time talking to journalists and educating physician colleagues and hospital employees about how the vaccine was developed so quickly and how it works. “Everyone asks me, ‘Should I get it? Are you going to get it?’ My answer is ‘yes’ and ‘yes,’ “ she said. “I am 1,000% confident that the benefits of widespread vaccination outweigh the risks of continued COVID and a continued pandemic.”

As the first American health care workers rolled up their sleeves for a COVID-19 vaccine, the images were instantly frozen in history, marking the triumph of scientific know-how and ingenuity. Cameras captured the first trucks pulling out of a warehouse in Portage, Mich., to the applause of workers and area residents. A day later, Boston Medical Center employees – some dressed in scrubs and wearing masks, face shields, and protective gowns – literally danced on the sidewalk when doses arrived. Some have photographed themselves getting the vaccine and posted it on social media, tagging it #MyCOVIDVax.
But the real story of the debut of COVID-19 vaccination is more methodical than monumental, a celebration of teamwork rather than of conquest. As hospitals waited for their first allotment, they reviewed their carefully drafted plans. They relied on each other, reaching across the usual divisions of competition and working collaboratively to share the limited supply. Their priority lists for the first vaccinations included environmental services workers who clean patient rooms and the critical care physicians who work to save lives.
“Health care workers have pulled together throughout this pandemic,” said Melanie Swift, MD, cochair of the COVID-19 Vaccine Allocation and Distribution Work Group at Mayo Clinic in Rochester, Minn. “We’ve gone through the darkest of years relying so heavily on each other,” she said. “Now we’re pulling together to get out of it.”
Still, a rollout of this magnitude has hitches. Stanford issued an apology Dec. 18 after its medical residents protested a vaccine distribution plan that left out nearly all of its residents and fellows, many of whom regularly treat patients with COVID-19.
There have already been more than 287,000 COVID-19 cases and 953 deaths among health care workers, according to the Centers for Disease Control and Prevention. In its guidance, the agency pointed out that the “continued protection of them at work, at home, and in the community remains a national priority.” That means vaccinating a workforce of about 21 million people, often the largest group of employees in a community.
“It collectively takes all of us to vaccinate our teams to maintain that stability in our health care infrastructure across the metro Atlanta area,” Christy Norman, PharmD, vice president of pharmacy services at Emory Healthcare, told reporters in a briefing as the health system awaited its first delivery.
Don’t waste a dose
One overriding imperative prevails: Hospitals don’t want to waste any doses. The storage requirements of the Pfizer vaccine make that tricky.
Once vials are removed from the pizza-box-shaped containers in ultracold storage and placed in a refrigerator, they must be used within 5 days. Thawed five-dose vials must be brought to room temperature before they are diluted, and they can remain at room temperature for no more than 2 hours. Once they are diluted with 1.8 mL of a 0.9% sodium chloride injection, the vials must be used within 6 hours.
COVID-19 precautions require employees to stay physically distant while they wait their turn for vaccination, which means the process can’t mirror typical large-scale flu immunization programs.
To prioritize groups, the vaccination planners at Mayo conducted a thorough risk stratification, considering each employee’s duties. Do they work in a dedicated COVID-19 unit? Do they handle lab tests or collect swabs? Do they work in the ICU or emergency department?
“We have applied some principles to make sure that as we roll it out, we prioritize people who are at greatest risk of ongoing exposure and who are really critical to maintaining the COVID response and other essential health services,” said Dr. Swift, associate medical director of Mayo’s occupational health service.
Mayo employees who are eligible for the first doses can sign up for appointments through the medical record system. If it seems likely that some doses will be left over at the end of the vaccination period – perhaps because of missed appointments – supervisors in high-risk areas can refer other health care workers. Mayo gave its first vaccines on Dec. 18, but the vaccination program began in earnest the following week. With the pleasant surprise that each five-dose vial actually provides six doses, 474 vials will allow for the vaccination of 2,844 employees in the top-priority group. “It’s going to expand each week or few days as we get more and more vaccine,” Dr. Swift said.
Sharing vials with small rural hospitals
Minnesota is using a hub-and-spoke system to give small rural hospitals access to the Pfizer vaccine, even though they lack ultracold storage and can’t use a minimum order of 975 doses. Large hospitals, acting as hubs, are sharing their orders. (The minimum order for Moderna is 100 doses.)
In south-central Minnesota, for example, two hub hospitals each have six spoke hospitals. Five of the 14 hospitals are independent, and the rest are part of large hospital systems, but affiliation doesn’t matter, said Eric Weller, regional health care preparedness coordinator for the South Central Healthcare Coalition. “We are all working together. It doesn’t matter what system you’re from,” he said. “We’re working for the good of the community.”
Each hospital designed a process to provide vaccine education, prioritize groups, allocate appointments, register people for vaccination, obtain signed consent forms, administer vaccines in a COVID-safe way, and provide follow-up appointments for the second dose. “We’re using some of the lessons we learned during H1N1,” said Mr. Weller, referring to immunization during the 2009 influenza pandemic. “The difference is that during H1N1, you could have lines of people.”
Coordinating the appointments will be more important than ever. “One of the vaccination strategies is to get people in groups of five, so you use one vial on those five people and don’t waste it,” he said.
Logistics are somewhat different for the Moderna vaccine, which will come in 10-dose vials that can be refrigerated for up to 30 days.
Both vaccines may produce mild flulike symptoms, such as fatigue, headache, or muscle pain, particularly after the second dose. That’s a sign that the immune system is reacting to the vaccine, but it’s also another consideration in the vaccination plans, because health care workers might take a day or two off work. “We’re not going to vaccinate a whole department at one time. It will be staggered,” said Kevin Smith, MD, medical director of the occupational medicine program at ProMedica, a health care system based in Toledo, Ohio.
Dr. Smith said he plans to encourage employees to use V-Safe, an app created by the CDC to track adverse effects in people who receive the vaccine. He pointed out that a day or two of achiness will be better than coping with the symptoms of COVID-19. Some employees who recovered from the infection still feel fatigued or haven’t regained their sense of taste and smell. “We are still monitoring quite a few employees to make sure they get back to 100%,” he said.

COVID-19 anticoagulation trials ‘paused’ for futility, safety
Parts of three linked studies investigating increased levels of anticoagulation in hospitalized COVID-19 patients have been “paused” because of futility and safety concerns, a statement from the U.S. National Heart, Lung, and Blood Institute (NHLBI) confirms.
The trials involved are the REMAP-CAP, ACTIV-4, and ATTACC studies.
The statement also says that a potential for harm in this subgroup could not be excluded, noting that increased bleeding is a known complication of full-dose anticoagulation. The trials are working urgently to undertake additional analyses, which will be made available as soon as possible.
The three clinical trial platforms are working together to test the effects of full therapeutic doses of anticoagulants vs. lower prophylactic doses in COVID-19 patients.
Informed by the deliberations of the data safety monitoring boards of these trials, all of the trial sites have paused enrollment of the most critically ill hospitalized patients with COVID-19.
Enrollment continues in the trials for moderately ill hospitalized COVID-19 patients, the statement notes.
“Whether the use of full-dose compared to low-dose anticoagulants leads to better outcomes in hospitalized patients with less COVID-19 severe disease remains a very important question,” the NHLBI statement says.
Patients who require full dose anticoagulants for another medical indication are not included in these trials.
The statement explains that COVID-19 is associated with significant inflammation and clinical and pathologic evidence of widespread blood clots. These trials were launched because clinicians have observed that many patients ill with COVID-19, including those who have died from the disease, formed blood clots throughout their bodies, even in their smallest blood vessels. This unusual clotting can cause multiple health complications, including lung failure, myocardial infarction, and stroke.
The three trials are the result of a collaboration between major international partners. The trials include: the Randomized, Embedded, Multi-factorial Adaptive Platform Trial for Community-Acquired Pneumonia (REMAP-CAP) Therapeutic Anticoagulation; Accelerating COVID-19 Therapeutic Interventions and Vaccines-4 (ACTIV-4) Antithrombotics Inpatient; and Antithrombotic Therapy to Ameliorate Complications of COVID-19 (ATTACC).
The trials, which span four continents, have the common goal of assessing the benefit of full doses of anticoagulants to treat moderately ill or critically ill adults hospitalized for COVID-19, compared with a lower dose often used to prevent blood clots in hospitalized patients.
In the United States, the ACTIV-4 trial is being led by a collaborative effort involving a number of universities, including the University of Pittsburgh and New York University.
The trials are supported by multiple international funding organizations including the National Institutes of Health, Canadian Institutes of Health Research, the National Institute for Health Research (UK), the National Health and Medical Research Council (Australia), and the PREPARE and RECOVER consortia (European Union).
