Locating the Latest Science-based Vaccine Recommendations

Locating the Latest Science-based Vaccine Recommendations

In June 2025, the composition of the committee that makes vaccine recommendations to the CDC, known as the ACIP, was dramatically changed, as were the processes by which these recommendations were made historically. The result has been recommendations not supported by the body of scientific evidence. The January 2025 immunization schedules are the last schedules available reflecting changes made using the Evidence to Recommendations (EtR) framework, long regarded as a comprehensive and rational methodology for creating immunization recommendations. The result has been a divergence of vaccine recommendations by professional societies composed of clinicians from those made by federal officials and the CDC. To assist clinicians in staying abreast of the latest science-based recommendations, we have developed a one-stop webpage that will be updated as recommendations change or as new statements become available. 

On March 16, 2026, a federal court determined that the changes to immunization recommendations did not follow established procedures. Although the case is not over, the court determined that changes since Robert F. Kennedy, Jr. was named Secretary of Health and Human Services must be stayed, meaning they should not be followed until the court case is decided. This included changes to COVID-19 recommendations and the childhood immunization schedule as well as all votes made by Mr. Kennedy’s hand-picked ACIP, such as the changes to the hepatitis B vaccine schedule. Dr. Paul Offit discussed this court decision in this video.

As many providers have been following the schedules and recommendations of professional societies during this time, this page continues to offer the latest information and science-based vaccine recommendations.

Birth to 18 years of age

The American Academy of Pediatrics (AAP) has been producing immunization schedules based on the recommendations of its Committee on Infectious Diseases (COID) since the 1930s. The recommendations are published in the Red Book. Between 1995 and early 2025, the AAP and CDC schedules were harmonized. However, in August 2025, the AAP published a schedule that diverged from CDC, following a review of the latest science related to fall respiratory viruses in particular COVID-19. In December 2025, they continued to recommend universal hepatitis B vaccination of newborns, regardless of a mother’s hepatitis B surface antigen (HBsAg) status. In January 2026, they continued to support the science-based schedule when the Department of Health and Human Services (HHS) announced changes to which vaccines are routinely recommended based on an internal, and nontransparent, review responding to an executive order to evaluate the schedule based on those of peer nations.

Recommendations vary for adults based on a variety of factors, such as age, occupation, and health status. The 2025 adult immunization schedule published in January 2025 was changed in July 2025 to reflect a discontinuation of the recommendation for COVID-19 vaccine during pregnancy, as directed by the Secretary of the Department of Health and Human Services (DHHS). These changes circumvented the usual recommendation process and were not supported with the presentation of any existing or new science to support the change. Quite the opposite, pregnancy remains a high-risk condition for severe COVID-19. As a result, many scientists and clinicians, as well as professional societies representing several physician groups, disagreed with the changes. Notably, in October 2025, the CDC schedule was quietly changed to include COVID-19 vaccination during pregnancy under shared clinical decision making (SCDM).

Because different groups of clinical specialists care for adults with various health-related conditions, several professional societies represent these clinicians. In this section, you will find links to recommendations or statements from these groups, organized by vaccine. If you do not see a vaccine listed, no statements regarding changes to the ACIP’s recommendations originally published in January 2025 on the adult immunization schedule have been made. The originally approved and published 2025 adult schedule is available on the American College of Physicians (ACP) website. 

The American Academy of Family Physicians (AAFP) has posted a 2026 version of the adult immunization schedule, along with a statement that they no longer endorse the CDC’s adult schedule. See the AAFP’s online schedule.

In February 2026, the American College of Obstetricians and Gynecologists (ACOG) released recommendations for providers caring for pregnant patients. See ACOG’s “Maternal Immunizations” recommendations.
