Immunize.org summarizes ACIP’s August 25–26 meeting with recommendations for clesrovimab and 2025–26 influenza vaccine
In an unprecedented move, on June 9 the Secretary of Health and Human Services dismissed ([link removed]) all 17 voting members of the Advisory Committee on Immunization Practices (ACIP) ([link removed]). On June 11, he named eight new voting members ([link removed]) to begin serving before the Committee’s June meeting. After the withdrawal of one appointee during a financial holdings review ([link removed]), the committee consisted of seven individuals when the meeting convened.
The newly appointed ACIP members met on June 25–26 ([link removed]). During the 1.5-day meeting, ACIP voted on the following topics:
* Recommendation of the long-acting monoclonal antibody clesrovimab as an option for RSV prevention in infants, and an accompanying VFC vote
* Influenza vaccine recommendations for the 2025–26 season, including use of influenza vaccines containing thimerosal as a preservative
The Committee also received updates on COVID-19, chikungunya, measles-mumps-rubella-varicella (MMRV), and anthrax vaccines. An anticipated vote on COVID-19 vaccines for the 2025–26 season was not held.
Presentation slides ([link removed]) are available online. Video recordings of the ACIP’s June 25 session ([link removed]) and the June 26 session ([link removed]) are archived at YouTube. Highlights of the meeting appear below.
New workgroups (announcement)
ACIP workgroups ([link removed]) traditionally review relevant data and develop vaccine recommendation options for consideration by the full Committee. During his introductory statements, newly-appointed ACIP Chair Martin Kulldorff announced two new workgroups. They will:
* examine CDC’s Recommended Child and Adolescent Immunization Schedule ([link removed]) to re-evaluate the number of recommended vaccines, potential vaccine interactions, the cumulative impact of vaccine ingredients, and the relative timing of different vaccines and
* review vaccines whose recommendations have not been reconsidered in more than 7 years (e.g., hepatitis B and MMR vaccines).
RSV vaccines: maternal/pediatric (information and vote)
Background
RSV is the leading cause of hospitalization in U.S. infants, with 2%–3% of young infants hospitalized annually. Approximately 80% of RSV-hospitalized infants have no underlying medical conditions. Most (68%) U.S. infants are infected in the first year of life, and nearly all (97%) have been infected by age 2 years.
In 2023, ACIP issued recommendations on use of two products to prevent RSV disease in infants:
* Maternal RSV Vaccine (Abrysvo ([link removed]), Pfizer) administered to pregnant women at 32–36 weeks gestation ([link removed]) during or just before RSV season
* Nirsevimab (Beyfortus ([link removed]), Sanofi and AstraZeneca), a long-acting monoclonal antibody administered to infants younger than age 8 months ([link removed]) during RSV season, with an additional dose recommended for children age 8 through 19 months who are at increased risk during their second RSV season
Uptake
CDC staff reported that 57% of infants born from April 2024 through March 2025 were protected from RSV by maternal vaccination or receipt of nirsevimab. The number of birthing hospitals enrolled in the Vaccines for Children (VFC) program increased substantially during this time, greatly expanding access to nirsevimab.
Impact
CDC presented information from two U.S population-based surveillance networks
demonstrating a greater than 30% reduction in RSV-associated hospitalizations (38% inRSV-NET ([link removed]) and 31% in the New Vaccine Safety Network ([link removed]) among children age 0 through 7 months in 2024–25 compared to RSV seasons before product introduction. These reductions were greatest (46%–47%) among infants age 0 through 2 months, the group at highest risk of hospitalization.
Safety
Safety studies after maternal vaccination showed no increased risk for most outcomes, including preterm birth or stillbirth. A small association was found between vaccination and hypertensive disorders of pregnancy (HDP), but the workgroup and the American College of Obstetricians and Gynecologists agreed this was not a concern, in part because the severity of HDP was similar between vaccinated and unvaccinated women based on rates of Caesarean section, admission after birth hospitalization, or length of stay.
Reassuring data was presented on the safety profile of nirsevimab use. Among 74,000 neonates who received nirsevimab across two seasons, there was no evidence of increased risk of seizures, immune thrombocytopenic purpura, drug reactions, fever, or sepsis. There were no cases of anaphylaxis. A small number of non-anaphylactic allergic reactions were seen. Simultaneous administration of nirsevimab with other vaccines did not result in increased rates of adverse events.
Clesrovimab
On June 9, FDA approved clesrovimab ([link removed]) (Enflonsia, Merck), a second long-acting preventive antibody against RSV infection in infants younger than age 8 months. Safety and clinical trial data for clesrovimab were presented at the April 2025 ACIP meeting ([link removed]) . The dosage for nirsevimab varies based on a child’s body weight, while clesrovimab is administered as a single dose without regard to weight. Clesrovimab is stored in the refrigerator. At this time, clesrovimab is not licensed for use during a child’s second RSV season. CDC indicated that infants who receive clesrovimab in their first season may receive nirsevimab in their second season when indicated.
ACIP members discussed the benefits of having two RSV preventive antibody products available. These include having options if resistance develops with either product, reducing the risk of a shortage if either product has an insufficient supply, and the possibility of competitive pricing. However, it may be challenging for providers who prefer to stock a single RSV antibody, as clesrovimab is not licensed for a child’s second RSV season. Either nirsevimab or clesrovimab may be used for infants younger than age 8 months born during or entering their first RSV season who are not protected by maternal vaccination.
ACIP voted (5 yes, 2 no) to recommend infants age younger than age 8 months born during or entering their first RSV season who are not protected by maternal vaccination receive one dose of clesrovimab.
In a separate vote, ACIP voted unanimously (7–0) to include clesrovimab in the Vaccines for Children program.
Influenza vaccines (information and votes)
Flublok update
Recombinant influenza vaccine (Flublok ([link removed]) , Sanofi) has been licensed since 2013 for use in persons age 18 years and older. In May 2025 FDA expanded the age indication of the vaccine to include children and adolescents age 9 through 17 years. Sanofi provided a review ([link removed]) of the company’s immunogenicity and safety studies showing the immune response and safety profile of the vaccine was comparable in the 9–17 year and adult age groups.
2024–25 influenza season
For the first time since 2017–18, the 2024–25 influenza season was classified as “high severity” across all indicators, with an estimated 56 million illnesses, 25 million medical visits, and 770,000 hospitalizations. In addition, the 2024–25 influenza season had the highest cumulative influenza-associated hospitalization rate since the 2010–11 season. Approximately 16% of hospitalized patients required ICU admission and 6% required invasive mechanical ventilation. The greatest burden of influenza disease was seen in people age 65 years and older. Influenza vaccine coverage varied by age group, ranging from 35%–71%. Preliminary information for 2024–25 indicates influenza vaccination prevented an estimated 12 million illnesses, 5.7 million hospitalizations, and 240,000 deaths. As of June 7, 246 influenza-associated pediatric deaths have been reported for the season, the highest number of pediatric deaths reported in any non-pandemic influenza season since the condition became reportable in
2004.
Thimerosal in influenza vaccines
Thimerosal is an ethylmercury-containing compound used since the 1930s in the United States as a preservative in multi-dose vials (MDVs) to help kill bacteria that can be introduced into a vial as needles puncture the vial stopper and doses are withdrawn. In 1999, FDA requested that all vaccine manufacturers remove thimerosal from childhood vaccines. This was done as a precautionary measure, not due to evidence of harm, but to reduce an infant’s overall exposure to mercury-containing compounds. By 2002, childhood vaccines licensed and recommended in the United States have been thimerosal-free. MDVs of influenza vaccine, primarily intended for adult vaccination campaigns, represent approximately 5% of influenza vaccine doses in the United States. Studies conducted since 1999 overwhelmingly confirmed that thimerosal in vaccines does not pose a health risk ([link removed]). Despite this, some groups continue to express concern about thimerosal, and the Committee heard a presentation highlighting these concerns. No presentation describing the substantial body of peer-reviewed evidence showing no harm from thimerosal was given. A briefing document, Thimerosal-Containing Vaccines and Neurodevelopmental Outcomes: Review of the Evidence ([link removed]), was posted on the ACIP website on June 24, but removed the next day. This extensively referenced document concluded: “Considering the breadth of evidence and consistency in results from multiple population-based studies conducted in several countries with various study designs, the evidence does not support an association between thimerosal-containing vaccines and autism spectrum disorder or other neurodevelopmental disorders.”
2025–26 recommendations
ACIP voted (6 yes, 1 abstain) to reaffirm recommendations for the 2025–26 influenza season for routine annual influenza vaccination of all people age 6 months and older who do not have contraindications.
In three separate votes, ACIP voted (5 yes, 1 no, 1 abstain) that seasonal influenza vaccines should be provided only in single dose formulations that are free of thimerosal as a preservative for (1) children age 18 years and younger, (2) pregnant women, and (3) all adults.
The 2025–26 influenza vaccines will include a new A/H3N2 strain and the same A/H1N1 and B/Victoria strains as the previous season. All U.S. seasonal influenza vaccines marketed for 2025–26 will be trivalent. Product options will include live attenuated influenza vaccine (FluMist ([link removed]), AstraZeneca) for self- or caregiver-administration ([link removed]).
COVID-19 vaccines (information only, no vote taken)
COVID-19 disease burden
COVID-19 continues to cause hospitalizations and death in the United States. CDC’s preliminary estimates from October 1, 2024, through June 7, 2025, indicate COVID-19 resulted in 9.8–16.1 million illnesses, 2.4–3.8 million outpatient visits, 270,000–440,000 hospitalizations, and 32,000–51,000 deaths. Long COVID also continues to be a significant public health issue. In 2023, 8.4% of adults and 1.4% of children reported having had long COVID.
COVID-19-associated hospitalizations from July 2024 through June 2025 were highest among adults age 75 years and older. Strikingly, rates of hospitalization in infants younger than age 6 months (268/100,000) were comparable to those among adults age 65 through 74 years (266/100,000). While most hospitalized adults had at least one underlying medical condition, 71% of hospitalized children younger than age 6 months and 54% of children age 6 through 23 months had no identified underlying medical condition before hospitalization. Half (50%) of SARS-CoV-2-positive pregnant women hospitalized from April 2024 through March 2025 with COVID-19 symptoms on admission had no underlying medical conditions. Approximately 1 in 4 hospitalized children younger than age 18 years required ICU admission. During 2024–25, 89% of COVID-19 vaccine-eligible children and adolescents hospitalized with COVID-19 had not received the most recently recommended COVID-19 vaccine. Similarly, most adults hospitalized with
COVID-19 had received no COVID-19 vaccine since July 2023.
COVID-19-related mortality decreased in 2024–25 compared to previous seasons. More than 75% of deaths occurred in adults age 75 years and older.
Vaccine coverage and effectiveness
COVID-19 vaccination coverage for older adults improved in 2024–25 compared to previous seasons, but overall coverage remains below previous years in all age groups. Coverage was estimated at 47%, 43%, and 23% for people age 75 years or older, 65 through 74 years, and 18 through 64 years, respectively. Approximately 13% of children age 6 months through 17 years were up to date with COVID-19 vaccination in April 2025. CDC presented data from several surveillance systems demonstrating the benefits of an in-season COVID-19 vaccination in reducing emergency department/urgent care visits in children, hospitalization in infants younger than age 5 months whose mothers were vaccinated, and both types of events in adults.
Vaccine safety
Extensive monitoring continues to support the overall safety of COVID-19 vaccines. Most reported adverse events are similar to those seen with other vaccines. An increased risk of myocarditis and pericarditis was seen after mRNA COVID-19 vaccination among adolescent and young adult males, most often after the second monovalent or first booster dose of mRNA COVID-19 vaccine. CDC follow-up studies show that 90% people for whom this adverse event was reported had fully or probably fully recovered by 1 year after vaccination. On June 25, FDA revised the package inserts for Comirnaty ([link removed]) (Pfizer) and Spikevax ([link removed]) (Moderna) regarding this rare adverse event. See accompanying story in this issue.
The majority (70%) of COVID-19 vaccine reports to the Vaccine Adverse Events Reporting System (VAERS) in children younger than age 12 years were vaccine administration errors likely due to the complexity of the recommendations. Multiple studies of COVID-19 vaccination in pregnant women showed no increased risk in maternal, pregnancy, or infant outcomes.
Chikungunya vaccines (information)
Due to time limitations, CDC provided an abbreviated presentation on the Evidence to Recommendations (EtR) developed by the chikungunya vaccine workgroup. The full presentation ([link removed]), including information on chikungunya disease severity and epidemiology, is available online.
Two chikungunya vaccines, a live attenuated vaccine (Ixchiq ([link removed]) , Valneva) and a virus-like particle vaccine (Vimkunya ([link removed]), Bavarian Nordic), are licensed for use in the United States. Recommendations ([link removed]) for these vaccines apply to certain travelers and laboratory workers at elevated risk of exposure. The chikungunya vaccine workgroup is continuing discussions on potential recommendations for these vaccines in U.S. territories and states where a risk of chikungunya virus transmission exists.
After several reports of serious cardiac and neurologic adverse events in older adults who received the live-attenuated vaccine (Ixchiq), on May 9 FDA and CDC recommended a temporary pause ([link removed]) in use of this vaccine in people age 60 years and older while these reports are being investigated.
Anthrax vaccine (information)
Anthrax vaccine adsorbed, adjuvanted (Cyfendus ([link removed]) , Emergent BioSolutions) was licensed in July 2023 for post-exposure prophylaxis after exposure to Bacillus anthracis in adults age 18 to 65 years. An anthrax vaccine workgroup is reviewing potential recommendations for domestic use of this vaccine. Results of their discussion will be reported at future ACIP meetings.
MMRV vaccine (information)
ACIP chair Martin Kuldorff reviewed the data for the slightly increased risk of febrile seizures in young children following receipt of MMRV vaccine (ProQuad ([link removed]), Merck) compared to separate doses of MMR and varicella. Additional discussion on this topic may occur at future ACIP meetings.
Next meeting
The next scheduled ACIP meeting will be held October 22–23, 2025, although the ACIP Meeting Information ([link removed]) web page notes that additional meetings may be held in September or October. Information about past and future ACIP meetings may be found on the ACIP website ([link removed]).

ACOG issues statement on COVID-19 vaccination during pregnancy, as well as a social media toolkit
A portion of a statement regarding COVID-19 vaccination during pregnancy from the American College of Obstetricians and Gynecologists ([link removed]) (ACOG) appears below.
Now more than ever, it’s critical to continue to recommend the routine administration of COVID-19 vaccines during pregnancy. Vaccine uptake data since the onset of the COVID-19 pandemic have consistently demonstrated that mRNA vaccines are safe and effective when given during pregnancy. Substantial scientific evidence continues to favor vaccination during pregnancy as the best way to prevent severe illness; extend protection to the pregnant patient, the fetus, the growing family, and the community; and strengthen immunization as a critical component of maternal care.
In addition, ACOG released a social media toolkit ([link removed]) , with ready-to-use messaging to help inform patients and clinicians about recommended vaccines for pregnant patients. Access and share their graphics, and resources ([link removed]) to support maternal immunization with your networks and to keep patients informed.

FDA updates warnings in mRNA COVID-19 vaccine labeling regarding myocarditis and pericarditis
On June 19, FDA revised the wording of warnings in labeling of mRNA COVID-19 vaccines ([link removed]) regarding myocarditis and pericarditis. A portion of their Safety Communication appears below. These risks and warnings ([link removed]) have been widely discussed since 2021.
FDA has required each manufacturer to update the warning about the risks of myocarditis and pericarditis to include information about (1) the estimated unadjusted incidence of myocarditis and/or pericarditis following administration of the 2023–2024 Formula of mRNA COVID-19 vaccines and (2) the results of a study that collected information on cardiac magnetic resonance imaging (cardiac MRI) in people who developed myocarditis after receiving an mRNA COVID-19 vaccine. FDA also required each manufacturer to describe the new safety information in the Adverse Reactions section of the Prescribing Information and in the Information for Recipients and Caregivers.
The Fact Sheets for Healthcare Providers and for Recipients and Caregivers for Moderna COVID-19 Vaccine and Pfizer-BioNTech COVID-19, which are authorized for emergency use in individuals 6 months through 11 years of age, have also been updated to include the new safety information in alignment with the Comirnaty and Spikevax Prescribing Information and Information for Recipients and Caregivers.

America’s founding is in part due to the success of immunization. Forces of the Continental Army, weakened by repeated outbreaks of smallpox, lost the battle of Québec City ([link removed](1775)) in December 1775 and were forced to retreat to Fort Ticonderoga. Later, George Washington ensured his troops were healthy enough to fight the British by having soldiers in the Continental Army inoculated against smallpox ([link removed]). Today, vaccines protect our military, police forces, frontline workers, schools, communities, and families.

"Global, Regional, and National Trends in Routine Childhood Vaccination Coverage from 1980 to 2023 with Forecasts to 2030: A Systematic Analysis for the Global Burden of Disease Study 2023" published in Lancet
In its June 24 issue, Lancet published Global, Regional, and National Trends in Routine Childhood Vaccination Coverage from 1980 to 2023 with Forecasts to 2030: A Systematic Analysis for the Global Burden of Disease Study 2023 ([link removed](25)01037-2/abstract) . The interpretation section appears below.
Our estimates of current vaccine coverage and forecasts to 2030 suggest that achieving IA2030 [Immunization Agenda 2030] targets, such as halving zero-dose children compared with 2019 levels and reaching 90% global coverage for life-course vaccines DTP3, PCV3, and MCV2, will require accelerated progress. Substantial increases in coverage are necessary in many countries and territories, with those in sub-Saharan Africa and south Asia facing the greatest challenges. Recent declines will need to be reversed to restore previous coverage levels in Latin America and the Caribbean, especially for DTP1, DTP3, and Pol3. These findings underscore the crucial need for targeted, equitable immunisation strategies. Strengthening primary health-care systems, addressing vaccine misinformation and hesitancy, and adapting to local contexts are essential to advancing coverage. COVID-19 pandemic recovery efforts, such as WHO's Big Catch-Up, as well as efforts to bolster routine services must prioritise
reaching marginalised populations and target subnational geographies to regain lost ground and achieve global immunisation goals.

Immunize.org summarizes ACIP’s August 25–26 meeting with recommendations for clesrovimab and 2025–26 influenza vaccine
In an unprecedented move, on June 9 the Secretary of Health and Human Services dismissed ([link removed]) all 17 voting members of the Advisory Committee on Immunization Practices (ACIP) ([link removed]). On June 11, he named eight new voting members ([link removed]) to begin serving before the Committee’s June meeting. After the withdrawal of one appointee during a financial holdings review ([link removed]), the committee consisted of seven individuals when the meeting convened.
The newly appointed ACIP members met on June 25–26 ([link removed]). During the 1.5-day meeting, ACIP voted on the following topics:
* Recommendation of the long-acting monoclonal antibody clesrovimab as an option for RSV prevention in infants, and an accompanying VFC vote
* Influenza vaccine recommendations for the 2025–26 season, including use of influenza vaccines containing thimerosal as a preservative
The Committee also received updates on COVID-19, chikungunya, measles-mumps-rubella-varicella (MMRV), and anthrax vaccines. An anticipated vote on COVID-19 vaccines for the 2025–26 season was not held.
Presentation slides ([link removed]) are available online. Video recordings of the ACIP’s June 25 session ([link removed]) and the June 26 session ([link removed]) are archived at YouTube. Highlights of the meeting appear below.
New workgroups (announcement)
ACIP workgroups ([link removed]) traditionally review relevant data and develop vaccine recommendation options for consideration by the full Committee. During his introductory statements, newly-appointed ACIP Chair Martin Kulldorff announced two new workgroups. They will:
* examine CDC’s Recommended Child and Adolescent Immunization Schedule ([link removed]) to re-evaluate the number of recommended vaccines, potential vaccine interactions, the cumulative impact of vaccine ingredients, and the relative timing of different vaccines and
* review vaccines whose recommendations have not been reconsidered in more than 7 years (e.g., hepatitis B and MMR vaccines).
RSV vaccines: maternal/pediatric (information and vote)
Background
RSV is the leading cause of hospitalization in U.S. infants, with 2%–3% of young infants hospitalized annually. Approximately 80% of RSV-hospitalized infants have no underlying medical conditions. Most (68%) U.S. infants are infected in the first year of life, and nearly all (97%) have been infected by age 2 years.
In 2023, ACIP issued recommendations on use of two products to prevent RSV disease in infants:
* Maternal RSV Vaccine (Abrysvo ([link removed]), Pfizer) administered to pregnant women at 32–36 weeks gestation ([link removed]) during or just before RSV season
* Nirsevimab (Beyfortus ([link removed]), Sanofi and AstraZeneca), a long-acting monoclonal antibody administered to infants younger than age 8 months ([link removed]) during RSV season, with an additional dose recommended for children age 8 through 19 months who are at increased risk during their second RSV season
Uptake
CDC staff reported that 57% of infants born from April 2024 through March 2025 were protected from RSV by maternal vaccination or receipt of nirsevimab. The number of birthing hospitals enrolled in the Vaccines for Children (VFC) program increased substantially during this time, greatly expanding access to nirsevimab.
Impact
CDC presented information from two U.S population-based surveillance networks
demonstrating a greater than 30% reduction in RSV-associated hospitalizations (38% inRSV-NET ([link removed]) and 31% in the New Vaccine Safety Network ([link removed]) among children age 0 through 7 months in 2024–25 compared to RSV seasons before product introduction. These reductions were greatest (46%–47%) among infants age 0 through 2 months, the group at highest risk of hospitalization.
Safety
Safety studies after maternal vaccination showed no increased risk for most outcomes, including preterm birth or stillbirth. A small association was found between vaccination and hypertensive disorders of pregnancy (HDP), but the workgroup and the American College of Obstetricians and Gynecologists agreed this was not a concern, in part because the severity of HDP was similar between vaccinated and unvaccinated women based on rates of Caesarean section, admission after birth hospitalization, or length of stay.
Reassuring data was presented on the safety profile of nirsevimab use. Among 74,000 neonates who received nirsevimab across two seasons, there was no evidence of increased risk of seizures, immune thrombocytopenic purpura, drug reactions, fever, or sepsis. There were no cases of anaphylaxis. A small number of non-anaphylactic allergic reactions were seen. Simultaneous administration of nirsevimab with other vaccines did not result in increased rates of adverse events.
Clesrovimab
On June 9, FDA approved clesrovimab ([link removed]) (Enflonsia, Merck), a second long-acting preventive antibody against RSV infection in infants younger than age 8 months. Safety and clinical trial data for clesrovimab were presented at the April 2025 ACIP meeting ([link removed]) . The dosage for nirsevimab varies based on a child’s body weight, while clesrovimab is administered as a single dose without regard to weight. Clesrovimab is stored in the refrigerator. At this time, clesrovimab is not licensed for use during a child’s second RSV season. CDC indicated that infants who receive clesrovimab in their first season may receive nirsevimab in their second season when indicated.
ACIP members discussed the benefits of having two RSV preventive antibody products available. These include having options if resistance develops with either product, reducing the risk of a shortage if either product has an insufficient supply, and the possibility of competitive pricing. However, it may be challenging for providers who prefer to stock a single RSV antibody, as clesrovimab is not licensed for a child’s second RSV season. Either nirsevimab or clesrovimab may be used for infants younger than age 8 months born during or entering their first RSV season who are not protected by maternal vaccination.
ACIP voted (5 yes, 2 no) to recommend infants age younger than age 8 months born during or entering their first RSV season who are not protected by maternal vaccination receive one dose of clesrovimab.
In a separate vote, ACIP voted unanimously (7–0) to include clesrovimab in the Vaccines for Children program.
Influenza vaccines (information and votes)
Flublok update
Recombinant influenza vaccine (Flublok ([link removed]) , Sanofi) has been licensed since 2013 for use in persons age 18 years and older. In May 2025 FDA expanded the age indication of the vaccine to include children and adolescents age 9 through 17 years. Sanofi provided a review ([link removed]) of the company’s immunogenicity and safety studies showing the immune response and safety profile of the vaccine was comparable in the 9–17 year and adult age groups.
2024–25 influenza season
For the first time since 2017–18, the 2024–25 influenza season was classified as “high severity” across all indicators, with an estimated 56 million illnesses, 25 million medical visits, and 770,000 hospitalizations. In addition, the 2024–25 influenza season had the highest cumulative influenza-associated hospitalization rate since the 2010–11 season. Approximately 16% of hospitalized patients required ICU admission and 6% required invasive mechanical ventilation. The greatest burden of influenza disease was seen in people age 65 years and older. Influenza vaccine coverage varied by age group, ranging from 35%–71%. Preliminary information for 2024–25 indicates influenza vaccination prevented an estimated 12 million illnesses, 5.7 million hospitalizations, and 240,000 deaths. As of June 7, 246 influenza-associated pediatric deaths have been reported for the season, the highest number of pediatric deaths reported in any non-pandemic influenza season since the condition became reportable in
2004.
Thimerosal in influenza vaccines
Thimerosal is an ethylmercury-containing compound used since the 1930s in the United States as a preservative in multi-dose vials (MDVs) to help kill bacteria that can be introduced into a vial as needles puncture the vial stopper and doses are withdrawn. In 1999, FDA requested that all vaccine manufacturers remove thimerosal from childhood vaccines. This was done as a precautionary measure, not due to evidence of harm, but to reduce an infant’s overall exposure to mercury-containing compounds. By 2002, childhood vaccines licensed and recommended in the United States have been thimerosal-free. MDVs of influenza vaccine, primarily intended for adult vaccination campaigns, represent approximately 5% of influenza vaccine doses in the United States. Studies conducted since 1999 overwhelmingly confirmed that thimerosal in vaccines does not pose a health risk ([link removed]). Despite this, some groups continue to express concern about thimerosal, and the Committee heard a presentation highlighting these concerns. No presentation describing the substantial body of peer-reviewed evidence showing no harm from thimerosal was given. A briefing document, Thimerosal-Containing Vaccines and Neurodevelopmental Outcomes: Review of the Evidence ([link removed]), was posted on the ACIP website on June 24, but removed the next day. This extensively referenced document concluded: “Considering the breadth of evidence and consistency in results from multiple population-based studies conducted in several countries with various study designs, the evidence does not support an association between thimerosal-containing vaccines and autism spectrum disorder or other neurodevelopmental disorders.”
2025–26 recommendations
ACIP voted (6 yes, 1 abstain) to reaffirm recommendations for the 2025–26 influenza season for routine annual influenza vaccination of all people age 6 months and older who do not have contraindications.
In three separate votes, ACIP voted (5 yes, 1 no, 1 abstain) that seasonal influenza vaccines should be provided only in single dose formulations that are free of thimerosal as a preservative for (1) children age 18 years and younger, (2) pregnant women, and (3) all adults.
The 2025–26 influenza vaccines will include a new A/H3N2 strain and the same A/H1N1 and B/Victoria strains as the previous season. All U.S. seasonal influenza vaccines marketed for 2025–26 will be trivalent. Product options will include live attenuated influenza vaccine (FluMist ([link removed]), AstraZeneca) for self- or caregiver-administration ([link removed]).
COVID-19 vaccines (information only, no vote taken)
COVID-19 disease burden
COVID-19 continues to cause hospitalizations and death in the United States. CDC’s preliminary estimates from October 1, 2024, through June 7, 2025, indicate COVID-19 resulted in 9.8–16.1 million illnesses, 2.4–3.8 million outpatient visits, 270,000–440,000 hospitalizations, and 32,000–51,000 deaths. Long COVID also continues to be a significant public health issue. In 2023, 8.4% of adults and 1.4% of children reported having had long COVID.
COVID-19-associated hospitalizations from July 2024 through June 2025 were highest among adults age 75 years and older. Strikingly, rates of hospitalization in infants younger than age 6 months (268/100,000) were comparable to those among adults age 65 through 74 years (266/100,000). While most hospitalized adults had at least one underlying medical condition, 71% of hospitalized children younger than age 6 months and 54% of children age 6 through 23 months had no identified underlying medical condition before hospitalization. Half (50%) of SARS-CoV-2-positive pregnant women hospitalized from April 2024 through March 2025 with COVID-19 symptoms on admission had no underlying medical conditions. Approximately 1 in 4 hospitalized children younger than age 18 years required ICU admission. During 2024–25, 89% of COVID-19 vaccine-eligible children and adolescents hospitalized with COVID-19 had not received the most recently recommended COVID-19 vaccine. Similarly, most adults hospitalized with
COVID-19 had received no COVID-19 vaccine since July 2023.
COVID-19-related mortality decreased in 2024–25 compared to previous seasons. More than 75% of deaths occurred in adults age 75 years and older.
Vaccine coverage and effectiveness
COVID-19 vaccination coverage for older adults improved in 2024–25 compared to previous seasons, but overall coverage remains below previous years in all age groups. Coverage was estimated at 47%, 43%, and 23% for people age 75 years or older, 65 through 74 years, and 18 through 64 years, respectively. Approximately 13% of children age 6 months through 17 years were up to date with COVID-19 vaccination in April 2025. CDC presented data from several surveillance systems demonstrating the benefits of an in-season COVID-19 vaccination in reducing emergency department/urgent care visits in children, hospitalization in infants younger than age 5 months whose mothers were vaccinated, and both types of events in adults.
Vaccine safety
Extensive monitoring continues to support the overall safety of COVID-19 vaccines. Most reported adverse events are similar to those seen with other vaccines. An increased risk of myocarditis and pericarditis was seen after mRNA COVID-19 vaccination among adolescent and young adult males, most often after the second monovalent or first booster dose of mRNA COVID-19 vaccine. CDC follow-up studies show that 90% people for whom this adverse event was reported had fully or probably fully recovered by 1 year after vaccination. On June 25, FDA revised the package inserts for Comirnaty ([link removed]) (Pfizer) and Spikevax ([link removed]) (Moderna) regarding this rare adverse event. See accompanying story in this issue.
The majority (70%) of COVID-19 vaccine reports to the Vaccine Adverse Events Reporting System (VAERS) in children younger than age 12 years were vaccine administration errors likely due to the complexity of the recommendations. Multiple studies of COVID-19 vaccination in pregnant women showed no increased risk in maternal, pregnancy, or infant outcomes.
Chikungunya vaccines (information)
Due to time limitations, CDC provided an abbreviated presentation on the Evidence to Recommendations (EtR) developed by the chikungunya vaccine workgroup. The full presentation ([link removed]), including information on chikungunya disease severity and epidemiology, is available online.
Two chikungunya vaccines, a live attenuated vaccine (Ixchiq ([link removed]) , Valneva) and a virus-like particle vaccine (Vimkunya ([link removed]), Bavarian Nordic), are licensed for use in the United States. Recommendations ([link removed]) for these vaccines apply to certain travelers and laboratory workers at elevated risk of exposure. The chikungunya vaccine workgroup is continuing discussions on potential recommendations for these vaccines in U.S. territories and states where a risk of chikungunya virus transmission exists.
After several reports of serious cardiac and neurologic adverse events in older adults who received the live-attenuated vaccine (Ixchiq), on May 9 FDA and CDC recommended a temporary pause ([link removed]) in use of this vaccine in people age 60 years and older while these reports are being investigated.
Anthrax vaccine (information)
Anthrax vaccine adsorbed, adjuvanted (Cyfendus ([link removed]) , Emergent BioSolutions) was licensed in July 2023 for post-exposure prophylaxis after exposure to Bacillus anthracis in adults age 18 to 65 years. An anthrax vaccine workgroup is reviewing potential recommendations for domestic use of this vaccine. Results of their discussion will be reported at future ACIP meetings.
MMRV vaccine (information)
ACIP chair Martin Kuldorff reviewed the data for the slightly increased risk of febrile seizures in young children following receipt of MMRV vaccine (ProQuad ([link removed]), Merck) compared to separate doses of MMR and varicella. Additional discussion on this topic may occur at future ACIP meetings.
Next meeting
The next scheduled ACIP meeting will be held October 22–23, 2025, although the ACIP Meeting Information ([link removed]) web page notes that additional meetings may be held in September or October. Information about past and future ACIP meetings may be found on the ACIP website ([link removed]).

ACOG issues statement on COVID-19 vaccination during pregnancy, as well as a social media toolkit
A portion of a statement regarding COVID-19 vaccination during pregnancy from the American College of Obstetricians and Gynecologists ([link removed]) (ACOG) appears below.
Now more than ever, it’s critical to continue to recommend the routine administration of COVID-19 vaccines during pregnancy. Vaccine uptake data since the onset of the COVID-19 pandemic have consistently demonstrated that mRNA vaccines are safe and effective when given during pregnancy. Substantial scientific evidence continues to favor vaccination during pregnancy as the best way to prevent severe illness; extend protection to the pregnant patient, the fetus, the growing family, and the community; and strengthen immunization as a critical component of maternal care.
In addition, ACOG released a social media toolkit ([link removed]) , with ready-to-use messaging to help inform patients and clinicians about recommended vaccines for pregnant patients. Access and share their graphics, and resources ([link removed]) to support maternal immunization with your networks and to keep patients informed.

FDA updates warnings in mRNA COVID-19 vaccine labeling regarding myocarditis and pericarditis
On June 19, FDA revised the wording of warnings in labeling of mRNA COVID-19 vaccines ([link removed]) regarding myocarditis and pericarditis. A portion of their Safety Communication appears below. These risks and warnings ([link removed]) have been widely discussed since 2021.
FDA has required each manufacturer to update the warning about the risks of myocarditis and pericarditis to include information about (1) the estimated unadjusted incidence of myocarditis and/or pericarditis following administration of the 2023–2024 Formula of mRNA COVID-19 vaccines and (2) the results of a study that collected information on cardiac magnetic resonance imaging (cardiac MRI) in people who developed myocarditis after receiving an mRNA COVID-19 vaccine. FDA also required each manufacturer to describe the new safety information in the Adverse Reactions section of the Prescribing Information and in the Information for Recipients and Caregivers.
The Fact Sheets for Healthcare Providers and for Recipients and Caregivers for Moderna COVID-19 Vaccine and Pfizer-BioNTech COVID-19, which are authorized for emergency use in individuals 6 months through 11 years of age, have also been updated to include the new safety information in alignment with the Comirnaty and Spikevax Prescribing Information and Information for Recipients and Caregivers.

America’s founding is in part due to the success of immunization. Forces of the Continental Army, weakened by repeated outbreaks of smallpox, lost the battle of Québec City ([link removed](1775)) in December 1775 and were forced to retreat to Fort Ticonderoga. Later, George Washington ensured his troops were healthy enough to fight the British by having soldiers in the Continental Army inoculated against smallpox ([link removed]). Today, vaccines protect our military, police forces, frontline workers, schools, communities, and families.

"Global, Regional, and National Trends in Routine Childhood Vaccination Coverage from 1980 to 2023 with Forecasts to 2030: A Systematic Analysis for the Global Burden of Disease Study 2023" published in Lancet
In its June 24 issue, Lancet published Global, Regional, and National Trends in Routine Childhood Vaccination Coverage from 1980 to 2023 with Forecasts to 2030: A Systematic Analysis for the Global Burden of Disease Study 2023 ([link removed](25)01037-2/abstract) . The interpretation section appears below.
Our estimates of current vaccine coverage and forecasts to 2030 suggest that achieving IA2030 [Immunization Agenda 2030] targets, such as halving zero-dose children compared with 2019 levels and reaching 90% global coverage for life-course vaccines DTP3, PCV3, and MCV2, will require accelerated progress. Substantial increases in coverage are necessary in many countries and territories, with those in sub-Saharan Africa and south Asia facing the greatest challenges. Recent declines will need to be reversed to restore previous coverage levels in Latin America and the Caribbean, especially for DTP1, DTP3, and Pol3. These findings underscore the crucial need for targeted, equitable immunisation strategies. Strengthening primary health-care systems, addressing vaccine misinformation and hesitancy, and adapting to local contexts are essential to advancing coverage. COVID-19 pandemic recovery efforts, such as WHO's Big Catch-Up, as well as efforts to bolster routine services must prioritise
reaching marginalised populations and target subnational geographies to regain lost ground and achieve global immunisation goals.
