Zika vaccine candidate shows promise in phase 1 trial
in a phase 1 study.
Although Zika cases have declined in recent years, “geographic expansion of the Aedes aegypti mosquito to areas where population-level immunity is low poses a substantial risk for future epidemics,” wrote Nadine C. Salisch, PhD, of Janssen Vaccines and Prevention, Leiden, the Netherlands, and colleagues in a paper published in Annals of Internal Medicine.
No vaccine against Zika is yet available, although more than 10 candidates have been studied in preclinical trials to date, they said.
The researchers randomized 100 healthy adult volunteers to an experimental Zika vaccine candidate known as Ad26.ZIKV.001 in either one-dose or two-dose regimens of 5x1010 viral particles (low dose) or 1x1011 viral particles (high dose) or placebo. Approximately half (55%) of the participants were women, and 72% were White.
Approximately 80% of patients in both two-dose groups showed antibody responses for a year after vaccination. Geometric mean titers (GMTs) reached peak of 823.4 in the low-dose/low-dose group and 961.5 in the high-dose/high-dose group. At day 365, the GMTs for these groups were 68.7 and 87.0, respectively.
A single high-dose vaccine achieved a similar level of neutralizing antibody titers, but lower peak neutralizing responses than the two-dose strategies, the researchers noted.
Most of the reported adverse events were mild to moderate, and short lived; the most common were injection site pain or tenderness, headache, and fatigue, the researchers said. After the first vaccination, 75% of participants in the low-dose groups, 88% of participants in high-dose groups, and 45% of participants receiving placebo reported local adverse events. In addition, 73%, 83%, and 40% of the participants in the low-dose, high-dose, and placebo groups, respectively, reported systemic adverse events. Reports were similar after the second vaccination. Two serious adverse events not related to vaccination were reported; one case of right lower lobe pneumonia and one case of incomplete spontaneous abortion.
The researchers also explored protective efficacy through a nonlethal mouse challenge model. “Transfer of 6 mg of IgG from Ad26.ZIKV.001 vaccines conferred complete protection from viremia in most recipient animals, with statistically significantly decreased breakthrough rates and cumulative viral loads per group compared with placebo,” they said.
The study findings were limited by the inability to assess safety and immunogenicity in an endemic area, the researchers noted. However, “Ad26.ZIKV.001 induces potent ZIKV-specific neutralizing responses with durability of at least 1 year, which supports further clinical development if an unmet medical need reemerges,” they said. “In addition, these data underscore the performance of the Ad26 vaccine platform, which Janssen is using for different infectious diseases, including COVID-19,” they noted.
Ad26 vector platform shows consistency
“Development of the investigational Janssen Zika vaccine candidate was initiated in 2015, and while the incidence of Zika virus has declined since the 2015-2016 outbreak, spread of the ‘carrier’ Aedes aegypti mosquito to areas where population-level immunity is low poses a substantial risk for future epidemics,” lead author Dr. Salisch said in an interview. For this reason, researchers say the vaccine warrants further development should the need reemerge, she said.
“Our research has found that while a single higher-dose regimen had lower peak neutralizing responses than a two-dose regimen, it achieved a similar level of neutralizing antibody responses at 1 year, an encouraging finding that shows our vaccine may be a useful tool to curb Zika epidemics,” Dr. Salisch noted. “Previous experience with the Ad26 vector platform across our investigational vaccine programs have yielded similarly promising results, most recently with our investigational Janssen COVID-19 vaccine program, for which phase 3 data show a single-dose vaccine met all primary and key secondary endpoints,” she said.
“The biggest barrier [to further development of the candidate vaccine] is one that we actually consider ourselves fortunate to have: The very low incidence of reported Zika cases currently reported worldwide,” Dr. Salisch said. “However, the current Zika case rate can change at any time, and in the event the situation demands it, we are open to alternative regulatory pathways to help us glean the necessary insights on vaccine safety and efficacy to further advance the development of this candidate,” she emphasized.
As for additional research, “there are still questions surrounding Zika transmission and the pathomechanism of congenital Zika syndrome,” said Dr. Salisch. “Our hope is that a correlate of protection against Zika disease, and in particular against congenital Zika syndrome, can be identified,” she said.
Consider pregnant women in next phase of research
“A major hurdle in ZIKV vaccine development is the inability to conduct large efficacy studies in the absence of a current outbreak,” Ann Chahroudi, MD, of Emory University, Atlanta, and Sallie Permar, MD, of Weill Cornell Medicine, New York, wrote in an accompanying editorial.
The current study provided some efficacy data using a mouse model, but “these data are obviously not conclusive for human protection,” they said.
“A further challenge for ZIKV vaccine efficacy trials will be to demonstrate fetal protection from [congenital Zika syndrome] after adult immunization. There should be a clear plan to readily deploy phase 3 trials for the most promising vaccines to emerge from phase 1 and 2 in the event of an outbreak, as was implemented for Ebola, including infant follow-up,” they emphasized.
The editorialists noted that the study did not include pregnant women, who represent a major target for immunization, but they said that vaccination of pregnant women against other neonatal pathogens such as influenza and tetanus has been effective. “Candidate ZIKV vaccines proven safe in phase 1 trials should immediately be assessed for safety and efficacy in pregnant women,” they said. Although Zika infections are not at epidemic levels currently, resurgence remains a possibility and the coronavirus pandemic “has taught us that preparedness for emerging infections is crucial,” they said.
Zika vaccine research is a challenge worth pursuing
“It is important to continue Zika vaccine research because of the unpredictable nature of that infection,” Kevin Ault, MD, of the University of Kansas, Kansas City, said in an interview. “Several times Zika has gained a foothold in unexposed and vulnerable populations,” Dr. Ault said. “Additionally, there are some data about using this vector during pregnancy, and eventually this vaccine may prevent the birth defects associated with Zika infections during pregnancy, he noted.
Dr. Ault said he was not surprised by the study findings. “This is a promising early phase vaccine candidate, and this adenovirus vector has been used in other similar trials,” he said. Potential barriers to vaccine development include the challenge of conducting late phase clinical trials in pregnant women, he noted. “The relevant endpoint is going to be clinical disease, and one of the most critical populations is pregnant women,” he said. In addition, “later phase 3 trials would be conducted in a population where there is an ongoing Zika outbreak,” Dr. Ault emphasized.
The study was supported by Janssen Vaccines and Infectious Diseases.

FROM ANNALS OF INTERNAL MEDICINE
2021 ACIP adult schedule released
The Advisory Committee on Immunization Practices of the Centers for Disease Control and Prevention has updated its recommended immunization schedule for adults for 2021.
A summary of the annual update was published online Feb. 11 in the CDC’s Morbidity and Mortality Weekly Report and is available in Annals of Internal Medicine and on the CDC website.
It features a special section on vaccination during the pandemic as well as interim recommendations on administering the Pfizer-BioNtech and Moderna COVID-19 vaccines.
The authors, led by Mark S. Freedman, DVM, MPH, DACVPM, of the CDC’s National Center for Immunization and Respiratory Diseases, in Atlanta, note that this year’s recommendations for adults – persons aged 19 years and older – are largely the same as last year’s. “There have been very few changes,” Dr. Freedman said in an interview. “Changes to the schedule tables and notes were made to harmonize to the greatest extent possible the adult and child/adolescent schedules.”
Changes in the schedule include new or updated ACIP recommendations for influenza, hepatitis A, hepatitis B (Hep B), and human papillomavirus (HPV) as well as for meningococcal serogroups A, C, W, and Y (MenACYW) vaccines, meningococcal B (MenB) vaccines, and the zoster vaccine.
Vaccine-specific changes
Influenza
The schedule highlights updates to the composition of several influenza vaccines, which apply to components in both trivalent and quadrivalent formulations.
The cover page abbreviation for live attenuated influenza vaccine (LAIV) was changed to LAIV4. The abbreviation for live recombinant influenza vaccine (RIV) was changed to RIV4.
For individuals with a history of egg allergy who experience reactions other than hives, the following procedural warning has been added: “If using an influenza vaccine other than RIV4 or ccIIV4, administer in medical setting under supervision of health care provider who can recognize and manage severe allergic reactions.”
Zoster
The zoster vaccine live (Zostavax) has been removed from the schedule because it is no longer available in the United States. The recombinant zoster vaccine Shingrix remains available as a 2-dose regimen for adults aged 50 years or older.
HPV
As in previous years, HPV vaccination is routinely recommended for persons aged 11-12 years, with catch-up vaccination for those aged 26 or younger. Catch-up vaccination can be considered with shared decision making for those aged 27 through 45. In this year’s schedule, in the pregnancy column, the color pink, which formerly indicated “delay until after pregnancy,” has been replaced with red and an asterisk, indicating “vaccinate after pregnancy.”
HepB
ACIP continues to recommend vaccination of adults at risk for HepB; however, the text overlay has been changed to read, “2, 3, or 4 doses, depending on vaccine or condition.” Additionally, HepB vaccination is now routinely recommended for adults younger than 60 years with diabetes. For those with diabetes who are older than 60, shared decision making is recommended.
Meningococcal vaccine
ACIP continues to recommend routine vaccination with a quadrivalent meningococcal conjugate vaccine (MenACWY) for persons at increased risk for meningococcal disease caused by serogroups A, C, W, or Y. The MenQuadfi (MenACWY-TT) vaccine, which was first licensed in 2020, has been added to all relevant sections of MenACWY vaccines. For MenACWY booster doses, new text addresses special situations, including outbreaks.
Improvements have been made to text and layout, Dr. Freedman said. An example is the minimizing of specialized text. Other changes were made to ensure more consistent text structure and language. Various fine-tunings of color and positioning were made to the cover page and tables, and the wording of the notes sections was improved.
Vaccination in the pandemic
The updated schedule outlines guidance on the use of COVID-19 vaccines approved by the Food and Drug Administration under emergency use authorization, with interim recommendations for the Pfizer-BioNTech COVID-19 vaccine for people aged 16 and older and the Moderna COVID-19 vaccine for people aged 18 and older.
The authors stress the importance of receiving the recommended routine and catch-up immunizations notwithstanding widespread anxiety about visiting medical offices. Last spring, the CDC reported a dramatic drop in child vaccinations after the declaration of the national emergency in mid-March, a drop attributed to fear of COVID-19 exposure.
“ACIP continued to meet and make recommendations during the pandemic,” Dr. Freedman said. “Our recommendation remains that despite challenges caused by the COVID-19 pandemic, adults and their healthcare providers should follow the recommended vaccine schedule to protect against serious and sometimes deadly diseases.”
Regular vaccines can be safely administered even as COVID-19 retains its grasp on the United States. “Healthcare providers should follow the CDC’s interim guidance for the safe delivery of vaccines during the pandemic, which includes the use of personal protective equipment and physical distancing,” Dr. Freedman said.
Dr. Freedman has disclosed no relevant financial relationships. Coauthor Henry Bernstein, DO, is the editor of the Current Opinion in Pediatrics Office Pediatrics Series, is a Harvard School of Public Health faculty member, and is a member of the data safety and monitoring board for a Takeda study on intrathecal enzymes for Hunter and San Filippo syndromes.

HepB
ACIP continues to recommend vaccination of adults at risk for HepB; however, the text overlay has been changed to read, “2, 3, or 4 doses, depending on vaccine or condition.” Additionally, HepB vaccination is now routinely recommended for adults younger than 60 years with diabetes. For those with diabetes who are older than 60, shared decision making is recommended.
Meningococcal vaccine
ACIP continues to recommend routine vaccination with a quadrivalent meningococcal conjugate vaccine (MenACWY) for persons at increased risk for meningococcal disease caused by serogroups A, C, W, or Y. The MenQuadfi (MenACWY-TT) vaccine, which was first licensed in 2020, has been added to all relevant sections of MenACWY vaccines. For MenACWY booster doses, new text addresses special situations, including outbreaks.
Improvements have been made to text and layout, Dr. Freedman said. An example is the minimizing of specialized text. Other changes were made to ensure more consistent text structure and language. Various fine-tunings of color and positioning were made to the cover page and tables, and the wording of the notes sections was improved.
Vaccination in the pandemic
The updated schedule outlines guidance on the use of COVID-19 vaccines approved by the Food and Drug Administration under emergency use authorization, with interim recommendations for the Pfizer-BioNTech COVID-19 vaccine for people aged 16 and older and the Moderna COVID-19 vaccine for people aged 18 and older.
The authors stress the importance of receiving the recommended routine and catch-up immunizations notwithstanding widespread anxiety about visiting medical offices. Last spring, the CDC reported a dramatic drop in child vaccinations after the declaration of the national emergency in mid-March, a drop attributed to fear of COVID-19 exposure.
“ACIP continued to meet and make recommendations during the pandemic,” Dr. Freedman said. “Our recommendation remains that despite challenges caused by the COVID-19 pandemic, adults and their healthcare providers should follow the recommended vaccine schedule to protect against serious and sometimes deadly diseases.”
Regular vaccines can be safely administered even as COVID-19 retains its grasp on the United States. “Healthcare providers should follow the CDC’s interim guidance for the safe delivery of vaccines during the pandemic, which includes the use of personal protective equipment and physical distancing,” Dr. Freedman said.
Dr. Freedman has disclosed no relevant financial relationships. Coauthor Henry Bernstein, DO, is the editor of the Current Opinion in Pediatrics Office Pediatrics Series, is a Harvard School of Public Health faculty member, and is a member of the data safety and monitoring board for a Takeda study on intrathecal enzymes for Hunter and San Filippo syndromes.

Teenagers get in the queue for COVID-19 vaccines
The vaccinations can’t come soon enough for parents like Stacy Hillenburg, a developmental therapist in Aurora, Ill., whose 9-year-old son takes immunosuppressants because he had a heart transplant when he was 7 weeks old. Although school-age children aren’t yet included in clinical trials, if her 12- and 13-year-old daughters could get vaccinated, along with both parents, then the family could relax some of the protocols they currently follow to prevent infection.
Whenever they are around other people, even masked and socially distanced, they come home and immediately shower and change their clothes. So far, no one in the family has been infected with COVID, but the anxiety is ever-present. “I can’t wait for it to come out,” Ms. Hillenburg said of a pediatric COVID vaccine. “It will ease my mind so much.”
She isn’t alone in that anticipation. In the fall, the American Academy of Pediatrics and other pediatric vaccine experts urged faster action on pediatric vaccine trials and worried that children would be left behind as adults gained protection from COVID. But recent developments have eased those concerns.
“Over the next couple of months, we will be doing trials in an age-deescalation manner,” with studies moving gradually to younger children, Anthony S. Fauci, MD, chief medical adviser on COVID-19 to the president, said in a coronavirus response team briefing on Jan. 29. “So that hopefully, as we get to the late spring and summer, we will have children being able to be vaccinated.”
Pfizer completed enrollment of 2,259 teens aged 12-15 years in late January and expects to move forward with a separate pediatric trial of children aged 5-11 years by this spring, Keanna Ghazvini, senior associate for global media relations at Pfizer, said in an interview.
Enrollment in Moderna’s TeenCove study of adolescents ages 12-17 years began slowly in late December, but the pace has since picked up, said company spokesperson Colleen Hussey. “We continue to bring clinical trial sites online, and we are on track to provide updated data around mid-year 2021.” A trial extension in children 11 years and younger is expected to begin later in 2021.
Johnson & Johnson and AstraZeneca said they expect to begin adolescent trials in early 2021, according to data shared by the Advisory Committee on Immunization Practices. An interim analysis of J&J’s Janssen COVID-19 vaccine trial data, released on Jan. 29, showed it was 72% effective in US participants aged 18 years or older. AstraZeneca’s U.S. trial in adults is ongoing.
Easing the burden
Vaccination could lessen children’s risk of severe disease as well as the social and emotional burdens of the pandemic, says James Campbell, MD, a pediatric infectious disease specialist at the University of Maryland’s Center for Vaccine Development in Baltimore, which was involved in the Moderna and early-phase Pfizer trials. He coauthored a September 2020 article in Clinical Infectious Diseases titled: “Warp Speed for COVID-19 vaccines: Why are children stuck in neutral?”
The adolescent trials are a vital step to ensure timely vaccine access for teens and younger children. “It is reasonable, when you have limited vaccine, that your rollout goes to the highest priority and then moves to lower and lower priorities. In adults, we’re just saying: ‘Wait your turn,’ ” he said of the current vaccination effort. “If we didn’t have the [vaccine trial] data in children, we’d be saying: ‘You don’t have a turn.’ ”
As the pandemic has worn on, the burden on children has grown. As of Tuesday, 269 children had died of COVID-19. That is well above the highest annual death toll recorded during a regular flu season – 188 flu deaths among children and adolescents under 18 in the 2019-2020 and 2017-2018 flu seasons.
Children are less likely to transmit COVID-19 in their household than adults, according to a meta-analysis of 54 studies published in JAMA Network Open. But that does not necessarily mean children are less infectious, the authors said, noting that unmeasured factors could have affected the spread of infection among adults.
Moreover, children and adolescents need protection from COVID infection – and from the potential for severe disease or lingering effects – and, given that there are 74 million children and teens in the United States, their vaccination is an important part of stopping the pandemic, said Grace Lee, MD, professor of pediatrics at Stanford (Calif.) University, and cochair of ACIP’s COVID-19 Vaccine Safety Technical Subgroup.
“In order to interrupt transmission, I don’t see how we’re going to do that without vaccinating children and adolescents,” she said.
Dr. Lee said her 16-year-old daughter misses the normal teenage social life and is excited about getting the vaccine when she is eligible. (Adolescents without high-risk conditions are in the lowest vaccination tier, according to ACIP recommendations.) “There is truly individual protection to be gained,” Dr. Lee said.
She noted that researchers continue to assess the immune responses to the adult vaccines – even looking at immune characteristics of the small percentage of people who aren’t protected from infection – and that information helps in the evaluation of the pediatric immune responses. As the trials expand to younger children and infants, dosing will be a major focus. “How many doses do they need they need to receive the same immunity? Safety considerations will be critically important,” she said.
Teen trials underway
Pfizer/BioNTech extended its adult trial to 16- and 17-year-olds in October, which enabled older teens to be included in its emergency-use authorization. They and younger teens, ages 12-15, receive the same dose as adults.
The ongoing trials with Pfizer and Moderna vaccines are immunobridging trials, designed to study safety and immunogenicity. Investigators will compare the teens’ immune response with the findings from the larger adult trials. When the trials expand to school-age children (6-12 years), protocols call for testing the safety and immunogenicity of a half-dose vaccine as well as the full dose.
Children ages 2-5 years and infants and toddlers will be enrolled in future trials, studying safety and immunogenicity of full, half, or even quarter dosages. The Pediatric Research Equity Act of 2003 requires licensed vaccines to be tested for safety and efficacy in children, unless they are not appropriate for a pediatric population.
Demand for the teen trials has been strong. At Cincinnati Children’s Hospital Medical Center, 259 teenagers joined the Pfizer/BioNTech trial, but some teenagers were turned away when the trial’s national enrollment closed in late January.
“Many of the children are having no side effects, and if they are, they’re having the same [effects] as the young adults – local redness or pain, fatigue, and headaches,” said Robert Frenck, MD, director of the Cincinnati Children’s Gamble Program for Clinical Studies.
Parents may share some of the vaccine hesitancy that has affected adult vaccination. But that is balanced by the hope that vaccines will end the pandemic and usher in a new normal. “If it looks like [vaccines] will increase the likelihood of children returning to school safely, that may be a motivating factor,” Dr. Frenck said.
Cody Meissner, MD, chief of the pediatric infectious disease service at Tufts Medical Center, Boston, was initially cautious about the extension of vaccination to adolescents. A member of the Vaccine and Related Biological Products Advisory Committee, which evaluates data and makes recommendations to the Food and Drug Administration, Dr. Meissner initially abstained in the vote on the Pfizer/BioNTech emergency-use authorization for people 16 and older.
He noted that, at the time the committee reviewed the Pfizer vaccine, the company had data available for just 134 teenagers, half of whom received a placebo. But the vaccination of 34 million adults has provided robust data about the vaccine’s safety, and the trial expansion into adolescents is important.
“I’m comfortable with the way these trials are going now,” he said. “This is the way I was hoping they would go.”
Ms. Hillenburg is on the parent advisory board of Voices for Vaccines, an organization of parents supporting vaccination that is affiliated with the Task Force for Global Health, an Atlanta-based independent public health organization. Dr. Campbell’s institution has received funds to conduct clinical trials from the National Institutes of Health and several companies, including Merck, GlaxoSmithKline, Sanofi, Pfizer, and Moderna. He has served pro bono on many safety and data monitoring committees. Dr. Frenck’s institution is receiving funds to conduct the Pfizer trial. In the past 5 years, he has also participated in clinical trials for GlaxoSmithKline, Merck, and Meissa vaccines. Dr. Lee and Dr. Meissner disclosed no relevant financial relationships.

CLL, MBL had lower response rates to flu vaccination, compared with healthy adults
Immunogenicity of the high-dose influenza vaccine (HD IIV3) in patients with chronic lymphocytic leukemia (CLL) and monoclonal B-cell lymphocytosis (MBL, the precursor state to CLL) was found lower than reported in healthy adults according to a report in Vaccine.
In addition, immunogenicity to influenza B was found to be greater in those patients with MBL, compared with those with CLL.
“Acute and chronic leukemia patients hospitalized with influenza infection document a case fatality rate of 25%-37%,” according to Jennifer A. Whitaker, MD, of the Mayo Clinic, Rochester, Minn., and colleagues in pointing out the importance of their study.
The prospective pilot study assessed the humoral immune responses of patients to the 2013-2014 and 2014-2015 HD IIV3 (Fluzone High-Dose; Sanofi Pasteur), which was administered as part of routine clinical care in 30 patients (17 with previously untreated CLL and 13 with MBL). The median patient age was 69.5 years.
The primary outcomes were seroconversion and seroprotection, as measured by hemagglutination inhibition assay (HAI).
Lower response rate
At day 28 post vaccination, the seroprotection rates for the overall cohort were 19/30 (63.3%) for A/H1N1, 21/23 (91.3%) for A/H3N2, and 13/30 (43.3%) for influenza B. Patients with MBL achieved significantly higher day 28 HAI geometric mean titers (GMT), compared with CLL patients (54.1 vs. 12.1]; P = .01), In addition, MBL patients achieved higher day 28 seroprotection rates against the influenza B vaccine strain virus than did those with CLL (76.9% vs. 17.6%; P = .002). Seroconversion rates for the overall cohort were 3/30 (10%) for A/H1N1; 5/23 (21.7%) for A/H3N2; and 3/30 (10%) for influenza B. No individual with CLL demonstrated seroconversion for influenza B, according to the researchers.
“Our studies reinforce rigorous adherence to vaccination strategies in patients with hematologic malignancy, including those with CLL, given the increased risk of serious complications among those experiencing influenza infection,” the authors stated.
“Even suboptimal responses to influenza vaccination can provide partial protection, reduce hospitalization rates, and/or prevent serious disease complications. Given the recent major issue with novel and aggressive viruses such COVID-19, we absolutely must continue with larger prospective studies to confirm these findings and evaluate vaccine effectiveness in preventing influenza or other novel viruses in these populations,” the researchers concluded.
This study was funded by the National Institutes of Health. Dr. Whitaker reported having no disclosures. Several of the coauthors reported financial relationships with a variety of pharmaceutical and biotechnology companies.

Immunogenicity of the high-dose influenza vaccine (HD IIV3) in patients with chronic lymphocytic leukemia (CLL) and monoclonal B-cell lymphocytosis (MBL, the precursor state to CLL) was found lower than reported in healthy adults according to a report in Vaccine.
In addition, immunogenicity to influenza B was found to be greater in those patients with MBL, compared with those with CLL.
“Acute and chronic leukemia patients hospitalized with influenza infection document a case fatality rate of 25%-37%,” according to Jennifer A. Whitaker, MD, of the Mayo Clinic, Rochester, Minn., and colleagues in pointing out the importance of their study.
The prospective pilot study assessed the humoral immune responses of patients to the 2013-2014 and 2014-2015 HD IIV3 (Fluzone High-Dose; Sanofi Pasteur), which was administered as part of routine clinical care in 30 patients (17 with previously untreated CLL and 13 with MBL). The median patient age was 69.5 years.
The primary outcomes were seroconversion and seroprotection, as measured by hemagglutination inhibition assay (HAI).
Lower response rate
At day 28 post vaccination, the seroprotection rates for the overall cohort were 19/30 (63.3%) for A/H1N1, 21/23 (91.3%) for A/H3N2, and 13/30 (43.3%) for influenza B. Patients with MBL achieved significantly higher day 28 HAI geometric mean titers (GMT), compared with CLL patients (54.1 vs. 12.1]; P = .01), In addition, MBL patients achieved higher day 28 seroprotection rates against the influenza B vaccine strain virus than did those with CLL (76.9% vs. 17.6%; P = .002). Seroconversion rates for the overall cohort were 3/30 (10%) for A/H1N1; 5/23 (21.7%) for A/H3N2; and 3/30 (10%) for influenza B. No individual with CLL demonstrated seroconversion for influenza B, according to the researchers.
“Our studies reinforce rigorous adherence to vaccination strategies in patients with hematologic malignancy, including those with CLL, given the increased risk of serious complications among those experiencing influenza infection,” the authors stated.
“Even suboptimal responses to influenza vaccination can provide partial protection, reduce hospitalization rates, and/or prevent serious disease complications. Given the recent major issue with novel and aggressive viruses such COVID-19, we absolutely must continue with larger prospective studies to confirm these findings and evaluate vaccine effectiveness in preventing influenza or other novel viruses in these populations,” the researchers concluded.

FROM VACCINE
The Veterans Health Administration Approach to COVID-19 Vaccine Allocation—Balancing Utility and Equity
The Veterans Health Administration (VHA) COVID-19 vaccine allocation plan showcases several lessons for government and health care leaders in planning for future pandemics.1 Many state governments—underresourced and overwhelmed with other COVID-19 demands—have struggled to get COVID-19 vaccines into the arms of their residents.2 In contrast, the VHA was able to mobilize early to identify vaccine allocation guidelines and proactively prepare facilities to vaccinate VHA staff and veterans as soon as vaccines were approved under Emergency Use Authorization by the US Food and Drug Administration.3,4
In August 2020, VHA formed a COVID-19 Vaccine Integrated Project Team, composed of 6 subgroups: communications, distribution, education, measurement, policy, prioritization, and vaccine safety. The National Center for Ethics in Health Care weighed in on the ethical justification for the developed vaccination risk stratification framework, which was informed by, but not identical to, that recommended by the Centers for Disease Control and Prevention Advisory Committee on Immunization Practices.5
Prioritizing who gets early access to a potentially life-saving vaccine weighs heavily on those leaders charged with making such decisions. The ethics of scarce resource allocation and triage protocols that may be necessary in a pandemic are often in tension with the patient-centered clinical ethics that health care practitioners (HCPs) encounter. HCPs require assistance in appreciating the ethical rationale for this shift in focus from the preference of the individual to the common good. The same is true for the risk stratification criteria required when there is not sufficient vaccine for all those who could benefit from immunization. Decisions must be transparent to ensure widespread acceptance and trust in the vaccination process. The ethical reasoning and values that are the basis for allocation criteria must be clearly, compassionately, and consistently communicated to the public, as outlined below. Ethical questions or concerns involve a conflict between core values: one of the central tasks of ethical analysis is to identify the available ethical options to resolve value conflicts. Several ethical frameworks for vaccine allocation are available—each balances and weighs the primary values of equity, dignity, beneficence, and utility slightly differently.6
For example, utilitarian ethics looks to produce the most good and avoid the most harm for the greatest number of people. Within this framework, there can be different notions of “good,” for example, saving the most lives, the most life years, the most quality life years, or the lives of those who have more life “innings” ahead. The approach of the US Department of Veterans Affairs (VA) focuses on saving the most lives in combination with avoiding suffering from serious illness, minimizing contagion, and preserving the essential workforce. Frameworks that give primacy to 1 notion of the good (ie, saving the most lives) may deprioritize other beneficial outcomes, such as allowing earlier return to work, school, and leisure activities that many find integral to human flourishing. Other ethical theories and principles may be used to support various allocation frameworks. For example, a pragmatic ethics approach might emphasize the importance of adapting the approach based on the evolving science and innovation surrounding COVID-19. Having more than 1 ethically defensible approach is common; the goal in ethics work is to be open to diversity of thought and reflect on the strength of one’s reasoning in resolving a core values conflict. We identify 2 central tenets of pandemic ethics that inform vaccine allocation.
1. Pandemic Ethics Requires Proactive Planning and Reevaluation of Continually Evolving Facts
There is an oft quoted saying among bioethicists: “Good ethics begins with good facts.” One obvious challenge during the COVID-19 pandemic has been the difficulty accessing up-to-date facts to inform decision making. If a main goal of a vaccination plan is to minimize the incidence of serious or fatal COVID-19 disease and contagion, myriad data points are needed to identify the best way to do this. For example, if 2 doses of the same vaccine are needed, this impacts the logistics of identifying, inviting, and scheduling eligible individuals and staffing vaccine clinics as well as ensuring that sufficient personal protective equipment and rescue equipment/medication are available to treat allergic reactions. If the adverse effects of vaccines lead to staff absenteeism or vaccine hesitancy, this needs to be factored into logistics.7 Tailored messaging is important to reduce appointment no-shows and vaccine nonadopters.8 Transportation to vaccination sites is a relevant factor: how a vaccine is stored, thawed, and reconstituted and its shelf life impacts whether it can be transported after thawing and what must be provided on site.
Consideration of the multifaceted factors influencing a successful vaccination campaign requires proactive planning and the readiness to pivot when new information is revealed. For example, vaccine appointment no-shows should be anticipated along with a fair process for allocating unused vaccine that would otherwise be wasted. This is an example of responsible stewardship of a scarce and life-saving resource. A higher than anticipated no-show rate would require revisiting a facility’s approach to ensuring that waste is avoided while the process is perceived to be fair and transparent. Ethical theories and principles cannot do all the work here; mindful attention to detail and proactive, informed planning are critical. Fortunately, the VA is well resourced in this domain, whereas many state health departments floundered in their response, causing unnecessary vaccination delays.9
2. Utility: Necessary But Insufficient
Most ethical approaches recognize to some extent that seeking good and minimizing harm is of value. However, a strictly utilitarian approach is insufficient to address the core values in conflict surrounding how best to allocate limited doses of COVID-19 vaccine. For example, some may argue that prioritizing the elderly or those in long-term care facilities like VA’s community living centers because they have the highest COVID-19 mortality rate produces less net benefit than prioritizing younger veterans with comorbidities or certain higher risk essential workers. There are 2 important points to make here.
First, the VHA vaccination plan balances utility with other ethical principles, namely, treating people with equal concern, and addressing health inequities, including a focus on justice and valuing the worth and dignity of each person. Rather than giving everyone an equal chance via lottery, the prioritization plan recognizes that some people have greater need or would stand to better mitigate viral contagion and preserve the essential workforce if they were vaccinated earlier. However, the principle of justice requires that efforts are made to treat like cases the same to avoid perceptions of bias, and to demonstrate respect for the dignity of each individual by way of promoting a fair vaccination process.
This requires transparency, consistency, and delivery of respectful and accurate communication. For example, the VA recognizes that lifetime exposure to social injustice produces health inequities that make Black, Hispanic, and Native American persons more susceptible to contracting COVID-19 and suffering serious or fatal illness. The approach to addressing this inequity is by giving priority to those with higher risk factors. Again, this is an example of blending and balancing ethical principles of utility and justice—that is, recognizing and remedying social injustice is of value both because it will help achieve better outcomes for persons of color and because it is inherently worthwhile to oppose injustice.
However, contrary to some news reports, the VHA approach does not allocate by race/ethnicity alone, as it does by age.10,11 Doing so would present logistical challenges—for example, race/ethnicity is not an objective classification as is age, and reconciling individuals’ self-reports could create confusion or chaos that is antithetical to a fair, streamlined vaccination program. Putting veterans of color at the front of the vaccination line could backfire by amplifying worries that they are being exposed to vaccine that is not fully tested (a common contributor to vaccine hesitancy, particularly among communities of color familiar with prior exploitation and abuse in the name of science).
Discriminating based on race/ethnicity alone in the spirit of achieving equity would be precedent setting for the VA and would require a strong ethical justification. The decision to prioritize for vaccine based on risk factors strives to achieve this balance of equity and utility, as it encompasses VA staff and veterans of color by way of their status as essential workers or those with comorbidities. However, it is important to address race-based access barriers and vaccine hesitancy to satisfy the equity demands. This effort is underway (eg, engaging community champions and developing tailored educational resources to reach diverse communities).
In addition, pragmatic ethics recognizes that an overly granular, complicated allocation plan would be inefficient to implement. While it might be true that some veterans who are aged < 65 years may be at higher risk from COVID-19 than some elderly veterans, achieving the goals of fairness and transparency requires establishing a vaccine prioritization plan that is both ethically defensible and feasibly implementable (ie, achieves its goal of getting “needles into arms”). For example, veterans aged ≥ 65 years may be invited to schedule their vaccination before younger veterans, but any veteran may be accepted “on-call” for vaccine appointment no-shows via first-come, first-served or by lottery. Flexibility of response is crucial. This played out in adding flexibility around the decision to vaccinate veterans aged ≥ 75 years before those aged 65 to 74 years, after revisiting how this prioritization might affect feasibility and throughput and opting to allow the opportunity to include those aged ≥ 65 years.
There will no doubt be additional modifications to the vaccine allocation plan as more data become available. Since the danger of fueling suspicion and distrust is high (ie, that certain privileged people are jumping the line, as we heard reports of in some non-VA facilities).12 There is an obvious ethical duty to explain why the chosen approach is ethically defensible. VA facility leaders should be able to answer how their approach achieves the goals of avoiding serious or fatal illness, reducing contagion, and preserving the essential workforce while ensuring a fair, respectful, evidence-based, and transparent process.

Is it an Allergic Reaction to the COVID-19 Vaccine—or COVID-19?
As of January 10, 2021, a reported 4,041,396 first doses of Moderna’s COVID-19 vaccine had been administered in the US. Reports of 1,266 (0.03%) adverse effects (AEs) after receipt of the vaccine were submitted to the Vaccine Adverse Event Reporting System (VAERS), according to researchers from the Centers for Disease Control and Prevention (CDC) COVID-19 Response Team and Food and Drug Administration in a Morbidity and Mortality Weekly Report early release.
The researchers screened VAERS reports that described suspected severe allergic reactions and anaphylaxis and collected information from medical records and outreach to healthcare facilities, providers, and recipients. They identified 108 reports for further review as possible severe allergic reaction, including anaphylaxis, a rare vaccination reaction. Ten cases were determined to be anaphylaxis—or a rate of 2.5 cases per million vaccine doses administered. Nine of the cases were people with a documented history of allergies or allergic reactions; 5 had a history of anaphylaxis.
The median interval from vaccine receipt to symptom onset was 7.5 minutes. Eight people had follow-up information available; all had recovered or were discharged. Of the case reports that were determined not to be anaphylaxis, 47 were assessed as nonanaphylactic allergic reactions and 47 were considered nonallergic adverse events. Four cases lacked enough information to be determined.
Based on those preliminary findings, it appears anaphylaxis is rare after the Moderna vaccination, but the researchers note that comparisons with other non–COVID-19 vaccines are constrained due to the limited information available this early in the vaccination program. They did cite an analysis of the Pfizer-BioNTech COVID-19 vaccine, also an mRNA vaccine, which estimated an initial rate of 11.1 cases per million doses after the first shot.
The researchers found a “strong female predominance” of anaphylaxis for both vaccines. All 10 anaphylaxis cases reported with the Moderna vaccine were in women. However, during the analytic period, 61% of first doses were given to women, vs 36% to men. Similarly, two thirds of first doses of the Pfizer-BioNTech vaccine were administered to women, and women were more affected.
Postvaccine COVID-19 Infections
But patients shouldn’t be too hasty to assume that symptoms after the vaccination are vaccine related, researchers at Israel’s Sheba Medical Center warn. The mere availability of a vaccine may lead to a certain laxity of precautions and a consequent rise in COVID-19 cases. “Thus, almost every physical complaint after vaccination poses a true diagnostic dilemma,” they point out, “as to whether an adverse reaction or a new COVID-19 infection is the cause.”
They studied 4,081 healthcare workers given the Pfizer-BioNTech vaccine. Of the vaccinated healthcare workers, 22 (0.54%) later had laboratory-confirmed COVID-19. Thirteen were tested because they had symptoms, usually an influenza-like illness that included fever, chills, cough, headache, myalgia, and sore throat. The median time between the first dose of vaccine and first symptoms was 3.5 days (one HCW had symptoms before immunization).
The vaccine, BNT162b2, is not likely to protect against clinical disease during the first days after receipt of the first dose, the researchers say. Efficacy was 52% a week after the first dose and positive COVID-19 cases were described among vaccinees even early after the second dose.
Clinicians should have a high level of suspicion of reported symptoms, the researchers advise, and avoid dismissing complaints as vaccine related until true infection is ruled out and the vaccine recipient is tested.

New campaign fights COVID-19 vaccine disinformation
As health care providers work against the clock to administer as many COVID-19 vaccine doses as soon as possible, logistics aren’t the only thing standing in their way.
Misinformation – which has hampered the nation’s coronavirus response – is now hurting vaccination efforts, too.
About one in five Americans say they won’t take a COVID-19 vaccine, according to the Kaiser Family Foundation’s COVID-19 Vaccine Monitor. Even a third of health care workers have voiced their hesitance.
The spread of COVID-19 vaccine misinformation creates “a really powerful parallel pandemic to the real pandemic,” Imran Ahmed, CEO of the Center for Countering Digital Hate, told NPR. The center has tracked the links between vaccine misinformation and vaccine hesitancy during the past year.
The “infodemic” is essentially “working in concert to really undermine our capacity to contain COVID,” Mr. Ahmed said.
To help combat vaccine misinformation and address lingering concerns that people have, corporate, nonprofit, and media leaders, including this news organization, are joining a public service campaign called VaxFacts. Led by HealthGuard, the goal of the campaign is to provide facts and tools to help consumers make informed decisions about vaccines.
Steven Brill, co-CEO of HealthGuard, said credible information that comes from trusted messengers is critical to counter vaccine hesitancy.
“There’s traditionally a lot of skepticism about vaccines. That has really ramped up in the last few years based on campaigns about the measles vaccine. ... And now you have the COVID vaccine, which by everybody’s understanding has been ‘rushed,’ ” Mr. Brill said during an interview on Coronavirus in Context, a video series hosted by John Whyte, MD, chief medical officer for WebMD.
“There may be less understanding of the nature of what rushed really means. It’s still gone through the clinical trials it needs to go through.”
HealthGuard is a browser extension that flags health hoaxes, provides credibility ratings for hundreds of websites, and guides users to sources that offer trusted information. The tool is a new service from NewsGuard, which veteran journalists Mr. Brill and co-CEO Gordon Crovitz created in 2018 to combat misinformation in the news. HealthGuard, which is free for users globally through June, is specifically aimed at informing readers about health myths related to vaccines and COVID-19. It will cost $35 per year after that.
The HealthGuard Coronavirus Tracking Center has flagged nearly 400 websites for publishing misinformation about the coronavirus, including several top myths about COVID-19 vaccines:
- The mRNA vaccines can alter human DNA.
- Vaccines will use microchip surveillance technology.
- COVID-19 vaccines cause infertility.
- The vaccine developed by Oxford University will turn people into monkeys.
- COVID-19 vaccines contain aborted human fetal tissue.
As a partner, this news organization will feature continuing coverage of COVID-19 vaccine misinformation, including articles and videos.
There will be other efforts this year. Google has launched a $3 million fund to back fact-checking organizations to counter vaccine misinformation, and social media platforms are monitoring posts that actively promote disinformation around vaccines.
The United States has distributed nearly 50 million vaccine doses, and states have administered more than 32 million of them, including 5.9 million second doses in the two-shot vaccines, according to the latest CDC update.
To reach herd immunity, about 75%-85% of Americans will need to receive a vaccine, Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, said in December 2020.
Vaccine skepticism has increased in recent years, which has led to a decline in vaccination rates and the highest annual number of measles cases in the United States in more than 25 years, according to the Pew Research Center. In 2019, the World Health Organization named vaccine hesitancy as 1 of 10 threats to global health.
With the COVID-19 vaccines in particular, people have voiced concerns about their safety and how well they work, given their accelerated development, according to Kaiser’s poll. They’re also worried about potential side effects, the perceived role of politics in the development process, and a lack of trust in government. Others don’t trust vaccines in general or believe they may contract COVID-19 from a vaccine, the Kaiser poll found, “suggesting that messages combating particular types of misinformation may be especially important for increasing vaccine confidence.”

Global Ebola vaccine stockpile established
The International Coordinating Group (ICG) on Vaccine Provision announced the establishment of a global Ebola vaccine stockpile initiative.
The ICG, which was established in 1997, is made up of the World Health Organization, the United Nations Children’s Fund, the International Federation of Red Cross and Red Crescent Societies, and Médecins Sans Frontières.
The stockpile was created in order to make the single-dose Ebola vaccine (rVSV∆G-ZEBOV-GP, live; trade name Everbo) rapidly available at the start of the next Ebola outbreak anywhere in the world. The vaccine was developed and is marketed by Merck Sharp & Dohme, with financial support from the United States.
The stockpile, which is maintained in Switzerland and managed by UNICEF, is designed to be readily deployed to other countries whenever there is an outbreak. The ICG will be the decision-making body for the vaccine’s allocation and release, as is also the case with previously created stockpiles of cholera, meningitis, and yellow fever vaccines.
“The decision to allocate the vaccine will be made within 48 hours of receiving a request from a country; vaccines will be made available together with ultra-cold chain packaging by the manufacturer for shipment to countries within 48 hours of the decision. The targeted overall delivery time from the stockpile to countries is 7 days,” according to the WHO press release.
Currently 6,890 doses are available for outbreak response, with further quantities to be delivered into the stockpile throughout 2021 and beyond. Initial use of the vaccine will be directed to health care and frontline workers. It is expected that it will take 2-3 years to reach the Strategic Advisory Group of Experts on Immunization–recommended level of 500,000 doses for the stockpile of Ebola vaccines.

The vaccine was developed and is marketed by Merck Sharp & Dohme, with financial support from the United States.
The stockpile, which is maintained in Switzerland and managed by UNICEF, is designed to be readily deployed to other countries whenever there is an outbreak. The ICG will be the decision-making body for the vaccine’s allocation and release, as is also the case with previously created stockpiles of cholera, meningitis, and yellow fever vaccines.
“The decision to allocate the vaccine will be made within 48 hours of receiving a request from a country; vaccines will be made available together with ultra-cold chain packaging by the manufacturer for shipment to countries within 48 hours of the decision. The targeted overall delivery time from the stockpile to countries is 7 days,” according to the WHO press release.
Currently 6,890 doses are available for outbreak response, with further quantities to be delivered into the stockpile throughout 2021 and beyond. Initial use of the vaccine will be directed to health care and frontline workers. It is expected that it will take 2-3 years to reach the Strategic Advisory Group of Experts on Immunization–recommended level of 500,000 doses for the stockpile of Ebola vaccines.

Moderna needs more kids for COVID vaccine trials
according to the company CEO and a federal official.
The Moderna vaccine was authorized for use in December and is now being given to people 18 and over. But children would receive lower doses, so new clinical trials must be done, Moderna CEO Stephane Bancel said at the JPMorgan virtual Health Care Conference on Monday.
Clinical trials on children 11 and younger “will take much longer, because we have to age deescalate and start at a lower dose. So we should not anticipate clinical data in 2021, but more in 2022,” Ms. Bancel said, according to Business Insider.
Moderna’s clinical trials for 12- to 17-year-olds started 4 weeks ago, but the company is having trouble getting enough participants, said Moncef Slaoui, PhD, the scientific head of Operation Warp Speed, the U.S. government’s vaccine effort. That could delay Food and Drug Administration approval, he said.
“It’s really very important for all of us, for all the population in America, to realize that we can’t have that indication unless adolescents aged 12-18 decide to participate,” Dr. Slaoui said, according to USA Today.
He said the adolescent trials are getting only about 800 volunteers a month, but need at least 3,000 volunteers to complete the study, USA Today reported. Parents interested in having their child participate can check eligibility and sign at this website.
The Pfizer/BioNTech vaccine won authorization for use in 16- to 17-year-olds as well as adults.
The coronavirus doesn’t appear to have as serious complications for children as for adults.
“At this time, it appears that severe illness due to COVID-19 is rare among children,” the American Association of Pediatrics says. “However, there is an urgent need to collect more data on longer-term impacts of the pandemic on children, including ways the virus may harm the long-term physical health of infected children, as well as its emotional and mental health effects.”
The association says 179 children had died of COVID-related reasons in 43 states and New York City as of Dec. 31, 2020. That’s about 0.06% of total COVID deaths, it says.
But children do get sick. As of Jan. 7, 2021, nearly 2.3 million children had tested positive for COVID-19 since the start of the pandemic, the association says.

Family physicians can help achieve national goals on STIs
Among these are the U.S. Department of Health and Human Services’ first “Sexually Transmitted Infections (STIs) National Strategic Plan for the United States,” which has a strong encompassing vision.
“The United States will be a place where sexually transmitted infections are prevented and where every person has high-quality STI prevention care, and treatment while living free from stigma and discrimination. The vision includes all people, regardless of age, sex, gender identity, sexual orientation, race, ethnicity, religion, disability, geographic location, or socioeconomic circumstance,” the new HHS plan states.1
Family physicians can and should play important roles in helping our country meet this plan’s goals particularly by following two important updated clinical guidelines, one from the U.S. Preventive Services Task Force (USPSTF) and another from the Centers for Disease Control and Prevention (CDC).
This strategic plan includes the following five overarching goals with associated objectives:
- Prevent New STIs.
- Improve the health of people by reducing adverse outcomes of STIs.
- Accelerate progress in STI research, technology, and innovation.
- Reduce STI-related health disparities and health inequities.
- Achieve integrated, coordinated efforts that address the STI epidemic.1
In my opinion, family physicians have important roles to play in order for each of these goals to be achieved.Unfortunately, there are approximately 20 million new cases of STIs each year, and the U.S. has seen increases in the rates of STIs in the past decade.
“Sexually transmitted infections are frequently asymptomatic, which may delay diagnosis and treatment and lead persons to unknowingly transmit STIs to others,” according to a new recommendation statement from the USPSTF.2 STIs may lead to serious health consequences for patients, cause harms to a mother and infant during pregnancy, and lead to cases of cancer among other concerning outcomes. As such, following the HHS new national strategic plan is critical for us to address the needs of our communities.
Preventing new STIs
Family physicians can be vital in achieving the first goal of the plan by helping to prevent new STIs. In August 2020, the USPSTF updated its guideline on behavioral counseling interventions to prevent STIs. In my opinion, the USPSTF offers some practical improvements from the earlier version of this guideline.
The task force provides a grade B recommendation that all sexually active adolescents and adults at increased risk for STIs be provided with behavioral counseling to prevent STIs. The guideline indicates that behavioral counseling interventions reduce the likelihood of those at increased risk for acquiring STIs.2
The 2014 guideline had recommended intensive interventions with a minimum of 30 minutes of counseling. Many family physicians may have found this previous recommendation impractical to implement. These updated recommendations now include a variety of interventions, such as those that take less than 30 minutes.
Although interventions with more than 120 minutes of contact time had the most effect, those with less than 30 minutes still demonstrated statistically significant fewer acquisitions of STIs during follow-up. These options include in-person counseling, and providing written materials, websites, videos, and telephone and text support to patients. These interventions can be delivered directly by the family physician, or patients may be referred to other settings or the media interventions.
The task force’s updated recommendation statement refers to a variety of resources that can be used to identify these interventions. Many of the studies reviewed for this guideline were conducted in STI clinics, and the guideline authors recommended further studies in primary care as opportunities for more generalizability.
In addition to behavioral counseling for STI prevention, family physicians can help prevent STIs in their patients through HPV vaccination and HIV pre-exposure prophylaxis (PrEP provision) within their practices. As the first contact for health care for many patients, we have an opportunity to significantly impact this first goal of prevention.
Treating STIs
Within the second goal of the national strategic plan is treatment of STIs, which family physicians should include in their practices as well as the diagnosis of STIs.
In December 2020, an update to the CDC’s treatment guideline for gonococcal infection was released. Prior to the publishing of this updated recommendation, the CDC recommended combination therapy of 250 mg intramuscular (IM) dose of ceftriaxone and either doxycycline or azithromycin. This recommendation has been changed to a single 500-mg IM dose of ceftriaxone for uncomplicated urogenital, anorectal, and pharyngeal gonorrhea. If chlamydia cannot be excluded, then the addition of oral doxycycline 100 mg twice daily for 7 days is recommended for nonpregnant persons, and 1 g oral azithromycin for pregnant persons. The previous treatment was recommended based on a concern for gonococcal resistance.
This updated guideline reflects increasing concerns for antimicrobial stewardship and emerging azithromycin resistance. It does not recommend a test-of-cure for urogenital or rectal gonorrhea, though did recommend a test-of-cure 7-14 days after treatment of pharyngeal gonorrhea. The guideline also recommends testing for reinfection 3-12 months after treatment as the rate of reinfection ranges from 7% to 12% among those previously treated.3
For some offices, the provision of the IM injection may be challenging, though having this medication in stock with the possibility of provision can greatly improve access and ease of treatment for patients. Family physicians can incorporate these updated recommendations along with those for other STIs such as chlamydia and syphilis with standing orders for treatment and testing within their offices.
Accelerating progress in STI research
Family physicians can also support the national strategic plan by participating in studies looking at the impact of behavioral counseling in the primary care office as opposed to in STI clinics. In addition, by following the STI treatment and screening guidelines, family physicians will contribute to the body of knowledge of prevalence, treatment failure, and reinfection rates of STIs. We can also help advance the research by providing feedback on interventions that have success within our practices.
Reducing STI-related health disparities and inequities
Family physicians are also in important places to support the strategic plan’s fourth goal of reducing health disparities and health inequities.
If we continue to ask the questions to identify those at high risk and ensure that we are offering appropriate STI prevention, care, and treatment services within our clinics, we can expand access to all who need services and improve equity. By offering these services within the primary care office, we may be able to decrease the stigma some may feel going to an STI clinic for services.
By incorporating additional screening and counseling in our practices we may identify some patients who were not aware that they were at risk for an STI and offer them preventive services.
Achieving integrated and coordinated efforts
Finally, as many family physicians have integrated practices, we are uniquely poised to support the fifth goal of the strategic plan of achieving integrated and coordinated efforts addressing the STI epidemic. In our practices we can participate in, lead, and refer to programs for substance use disorders, viral hepatitis, STIs, and HIV as part of full scope primary care.
Family physicians and other primary care providers should work to support the entire strategic plan to ensure that we are fully caring for our patients and communities and stopping the past decade’s increase in STIs. We have an opportunity to use this strategy and make a large impact in our communities.
