Immunize​.org summarizes ACIP’s February 22–24 meeting recommending mpox vaccine for adults during outbreaks and discussing RSV, pneumococcal disease, meningococcal disease, future COVID-19 vaccine plans, and more

The Advisory Committee on Immunization Practices (ACIP) met on February 22–24, 2023. The 3-day meeting included a single vote to recommend use of mpox vaccine in adults age 18 years and older during outbreaks. The Committee also received informational updates on influenza and vaccines under consideration by FDA for pneumococcal, meningococcal, chikungunya, dengue, and respiratory syncytial virus (RSV) in adults, as well as updates on nirsevimab (a long-acting monoclonal antibody) being evaluated by FDA to prevent RSV in infants. The third day was devoted to reviewing COVID-19 vaccine safety and discussing future plans for vaccine use. Presentation slides are available online. Highlights of the meeting are provided below.
 
Mpox vaccine
Since May 2022, more than 30,000 cases of mpox were reported in the United States, largely among gay, bisexual, and other men who have sex with men. Cases continue to occur at a low rate. In August 2022, FDA issued an emergency use authorization (EUA) for the licensed Jynneos vaccine (Bavarian Nordic) when used for pre- or post-exposure prophylaxis in children and for intradermal administration in adults. CDC maintains Interim Clinical Considerations for Use of JYNNEOS and ACAM2000 Vaccines during the 2022 U.S. Mpox Outbreak to guide use of these two vaccines, although ACAM2000 is not being used in the current outbreak. Almost 1.2 million doses of Jynneos have been administered since the outbreak began.
 
Before this February meeting, ACIP had not issued a recommendation for use of Jynneos during outbreaks. The Committee reviewed data on Jynneos vaccine effectiveness (66%–83% after 2 doses, regardless of route of administration) and safety. No new safety concerns have been identified; to date, safety surveillance systems have not detected any increased risk of myocarditis or pericarditis following receipt of Jynneos. ACIP voted unanimously to recommend the 2-dose Jynneos series for people age 18 years and older at risk of mpox during an mpox outbreak. As a part of this new recommendation, subcutaneous administration will be recommended unless supply constraints necessitate intradermal administration. ACIP will consider use of the vaccine in people younger than age 18 years during its June 2023 meeting. Plans for a longer-term vaccination strategy for 2-dose Jynneos will be considered at the October 2023 meeting. ACIP and CDC emphasized that the current U.S. mpox vaccination strategy remains active; populations at high risk should continue to be vaccinated.
 
Influenza vaccine
Influenza activity in the United States peaked early this season, in late November/early December 2022. Influenza A(H3N2) has been the predominant subtype to date. The preliminary estimate for 2022–23 overall vaccine effectiveness is 49% against laboratory-confirmed influenza illness. This season’s vaccine provides substantial protection against hospitalization and among important high-risk groups, such as persons age 65 years and older and those who are immunocompromised.
 
Pneumococcal vaccine (PCV20)
Pneumococcal conjugate vaccines (PCVs) currently recommended in the United States include PCV13 and PCV15 for children and PCV15 and PCV20 for adults. In addition, PPSV23 (pneumococcal polysaccharide vaccine) is recommended for certain children based on their risk and for adults with certain high-risk conditions, including those who previously received PCV13 and PCV15. Use of PCV20 in children is under FDA review and could be licensed as soon as April 2023. ACIP reviewed potential PCV20 dosing schedules for children younger than age 2 years, as well as considerations for using PCV20 instead of PPSV23 in older children who have underlying medical conditions. ACIP will vote on updated recommendations after anticipated FDA licensure of the PCV20 vaccine for pediatric use.
 
Meningococcal vaccine
ACIP members heard an overview of the epidemiology of meningococcal disease in the United States, and updates on pentavalent (MenABCWY) vaccines from Pfizer and GSK that are being evaluated by FDA. ACIP’s meningococcal vaccine workgroup will continue to review available information on these vaccines. Current MenACWY and MenB vaccines are offered at differing ages and with different dosing schedules. The committee may consider adjusting the schedules when incorporating pentavalent meningococcal vaccines into the adolescent schedule. ACIP will continue this discussion at the June meeting, with a potential vote in October 2023.
 
RSV prophylaxis (pediatric/maternal)
Respiratory syncytial virus (RSV) infection is associated with millions of outpatient visits, up to 80,000 hospitalizations, and up to 300 deaths in U.S. children less than 5 years of age each year. RSV is the most common cause of hospitalization in U.S. infants, most of whom were healthy before infection. RSV transmission typically increases during winter months, though transmission outside the usual season occurred during the COVID-19 pandemic. No RSV vaccine is currently licensed. The long-acting monoclonal antibody nirsevimab (Sanofi), intended for intramuscular injection of infants or newborns once in a season, was found effective in RSV prevention. Nirsevimab is the first passive immunization product to be considered for inclusion by ACIP in the CDC immunization schedule as a vaccine-like seasonal immunization. ACIP heard discussion of cost effectiveness. Members stressed the value of including it in the Vaccines for Children (VFC) program to ensure access for all infants. ACIP also received a presentation on use of a maternal RSV vaccine (Pfizer) being evaluated by FDA for use at 24 to 36 weeks gestation for prevention of RSV infection in pregnant persons to protect them and their newborn children. More information about this product will be presented at later ACIP meetings.
 
RSV vaccines (older adults)
RSV is a frequent, often unrecognized, cause of severe respiratory illness in adults. It is associated with more than 1 million medical encounters and 6,000–10,000 deaths per year among U.S. adults age 65 years and older. Two RSV vaccines for adults (GSK and Pfizer) are being evaluated by FDA. ACIP began a discussion of GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) information for each vaccine, assuming vaccination beginning at age 60 or 65 years. Members discussed vaccine safety and the limited information available on the duration of vaccine effectiveness, which may extend to two seasons. Additional information on duration of protection will become available later in 2023.
 
Other vaccines: polio, chikungunya, dengue
ACIP reviewed surveillance data and discussed clarifying and updating recommendations for the use of inactivated polio vaccine as a primary series or booster dose for U.S. adults. A vote is anticipated in June 2023. The committee discussed the burden of chikungunya disease and potential benefit of a future vaccine. The committee also reviewed the epidemiology of dengue disease and heard preliminary information on a new dengue vaccine from Takeda that has been submitted for FDA licensure. 
 
COVID-19 vaccines
The third day of the ACIP meeting included CDC presentations on COVID-19 vaccine effectiveness and safety, a risk-benefit assessment of updated (bivalent) mRNA COVID-19 vaccination, and preliminary discussions about future updates to COVID-19 vaccine recommendations.
 
Data continue to show that COVID-19 vaccines are highly effective at preventing serious disease outcomes in all age groups. Data through December 2022 indicate that the hospitalization rate of unvaccinated adults was 16 times higher than the hospitalization rate of adults who received a recommended bivalent mRNA booster. The rate among vaccinated adults who lacked a bivalent booster was 2.6 times higher than those who had received one.
 
COVID-19 vaccines continue to undergo the most extensive vaccine safety monitoring in U.S. history. Information is continually evaluated through multiple surveillance systems, including the Vaccine Adverse Event Reporting System (VAERS), v-safe, and the Vaccine Safety Datalink (VSD) system. In November 2022, a possible safety signal for ischemic stroke in adults age 65 years and older after the Pfizer-BioNTech bivalent COVID-19 vaccination was detected in VSD. No similar signal was seen in any other vaccine safety surveillance system in the United States or internationally, and no signal was seen after the Moderna bivalent COVID-19 vaccination. Additional analysis indicates the signal was stronger following simultaneous administration of the Pfizer-BioNTech bivalent booster and influenza vaccine. Presenters emphasized that the small signal has diminished since it was first detected and could be the result of patient conditions or simply a chance finding. Current information cannot prove a causal link, and researchers will continue to investigate. Ischemic stroke is also a frequent complication of COVID-19 disease. CDC recommends that vaccination continue without modification. Additional safety data presented at the meeting showed no increased risk of myocarditis in adolescent males following receipt of a bivalent booster dose.
 
The ACIP meeting concluded with a robust discussion of considerations for simplifying COVID-19 vaccination recommendations later this year. Committee members discussed whether to end the recommendation for a 2-dose primary series in immunocompetent older children and adults, and whether to adopt a 1-dose schedule after early childhood, now that data show the immune systems of almost all U.S. residents have been primed through vaccination, infection, or both. They also discussed the potential use of bivalent vaccines for both the primary series and booster doses, if approved by FDA. Eliminating monovalent vaccines would reduce the recommended formulations from 11 different mRNA COVID-19 products to five, eliminating look-alike vials and decreasing vaccine administration errors. Novavax monovalent COVID-19 vaccine also remains available as an option.
 
ACIP and CDC continue to emphasize the importance of following all current COVID-19 vaccine recommendations. Up-to-date vaccine coverage remains relatively low in all age groups, but extremely low in young children and adolescents. Fewer than half of adults age 65 years and older have received an updated COVID-19 booster.
 
Varicella vaccine: 25th anniversary
The committee heard a review of the 25th anniversary of routine varicella vaccination in the United States. The CDC presenter summarized the tremendous success of the U.S. varicella vaccination program, including prevention of up to 91 million cases of chickenpox, 238,000 hospitalizations for chickenpox, and up to 2,446 deaths. These benefits have saved society more than $23 billion.
 
The next scheduled ACIP meeting will be held on June 21–22, 2023, although additional emergency meetings may be announced before that time. Information about past and future ACIP meetings may be found on the ACIP website.

Influenza activity is low, but vaccines work, so with weeks of winter still ahead, keep vaccinating

Keep encouraging influenza vaccination for those not yet protected. This is especially important for young children who still need a second dose in their first vaccination season and those who need vaccination during pregnancy.

CDC’s Weekly U.S. Influenza Surveillance Report, FluView, provides a valuable snapshot of influenza activity state by state. For week 7, ending February 14, FluView reports that 2.6% of outpatient visits nationwide were due to respiratory illness that included fever plus a cough or sore throat (i.e., influenza-like illness [ILI]). The national baseline is 2.5%. Multiple respiratory viruses are co-circulating; the relative contribution of influenza virus infection to ILI varies by location. So far this season, 115 children died from influenza-associated causes.



Influenza Vaccination Effectiveness Estimates
CDC posted a web spotlight on influenza vaccine effectiveness (VE) this season. Estimates show that influenza vaccine provided substantial protection this season. From September 13, 2022, to January 25, 2023, vaccinated children were 68% less likely to be hospitalized due to influenza illness or related complications, and 42% less likely to visit an emergency department. Overall, vaccination reduced the risk of hospitalization or emergency department visits for influenza by 49% in all ages.

Influenza Vaccination Dashboard
CDC’s Weekly Flu Vaccination Dashboard shows that coverage this season for children age 6 months to 4 years is 8.6 percentage points higher compared with children age 5 to 12 years (62.4% compared with 53.8%) and 18.1 percentage points higher compared with children age 13 to 17 years (62.4% compared with 44.4%).

CDC recommends everyone age 6 months and older get annual influenza vaccination. “Vaccines.gov” offers VaccineFinder, a service of Boston Children’s Hospital, to help people find influenza and COVID-19 vaccines for any age group. To be listed as a provider by VaccineFinder, see the information at this website.

Global News

WHO posts “African Leaders Call for Urgent Action to Revitalize Routine Immunization”

On February 19, WHO posted an article titled, African Leaders Call for Urgent Action to Revitalize Routine Immunization. A portion of the article appears below.

African heads of state today agreed on key measures to revamp routine immunization across the continent following massive disruptions by the COVID-19 pandemic that stymied childhood vaccination programmes and heightened outbreaks of vaccine-preventable diseases.

A total of 8.4 million children in the African region, compared with 18 million globally, were left out by immunization services in 2021, according to estimates by UNICEF and World Health Organization (WHO). Access to immunization services is even more difficult among poor or marginalized communities or those rendered vulnerable by conflicts or living in fragile settings.
