A meeting of the Centers for Disease Control and Prevention’s (CDC) Advisory Committee on Immunization Practices (ACIP), originally scheduled for February 25-27, has been postponed, according to reports. The delay comes as the panel faces legal challenges questioning its legitimacy and as Health and Human Services Secretary Robert F. Kennedy Jr. Continues to pursue significant changes to federal vaccination policy.
The ACIP plays a critical role in shaping vaccine recommendations in the United States, influencing not only which vaccines are advised for both children and adults but similarly impacting insurance coverage, school vaccination requirements, and physician guidance. The postponement, first reported by Bloomberg, is linked to a legal challenge filed by the American Academy of Pediatrics (AAP), raising concerns about the committee’s current composition, and authority.
Kennedy Jr., a long-time critic of vaccines, has moved swiftly since taking office to reshape the ACIP. In June 2025, he removed all 17 existing members and, with one exception, appointed individuals either openly skeptical of vaccines or lacking expertise in the field, according to reports. This overhaul has sparked widespread concern among public health experts.
The AAP’s legal challenge centers on the validity of the reconstituted committee, questioning whether the new members possess the necessary qualifications to provide sound scientific advice on vaccination practices. The panel is now expected to reconvene in March, though a specific date has not yet been announced. The CDC’s website confirms the postponement but provides limited details regarding the legal challenge.
Changes to Childhood Immunization Schedules
Beyond the composition of the ACIP, Kennedy Jr.’s administration has initiated changes to recommended childhood immunizations. These include removing broad recommendations for six routine vaccines, including those for COVID-19 and hepatitis B. The administration is also reportedly seeking to increase federal support for state-level vaccine exemptions and reduce funding for research into mRNA-based vaccines. These moves have raised alarms among medical professionals who emphasize the decades of evidence supporting the safety and efficacy of vaccines.
Last year, the ACIP made a controversial decision to end the longstanding recommendation that all infants receive the hepatitis B vaccine. According to the CDC, the ACIP develops recommendations on how to use vaccines to control disease in the U.S. Civilian population. More information about ACIP recommendations can be found on the CDC website.
The committee’s recommendations traditionally have a broad impact, influencing health insurance coverage nationwide and state requirements for school vaccinations. The ACIP was established in March 1964 by the US Surgeon General to assist in preventing and controlling communicable diseases. Learn more about the history and function of the ACIP from Wikipedia.
Leadership Changes at the CDC
The postponement of the ACIP meeting coincides with broader leadership changes at the CDC. National Institutes of Health (NIH) director Jay Bhattacharya is set to serve as acting director of the CDC, taking over from Jim O’Neill. These changes add to the growing sense of uncertainty surrounding federal public health policy.
Experts have expressed concerns about vaccine safety in light of the changes to the ACIP and the increasing visibility of groups advocating for alternative health approaches, such as the “Maha” (“Make America healthy again”) movement. Last month, the ACIP’s top advisor indicated the committee was reconsidering all vaccine recommendations, signaling a potentially significant shift in policy.
The ACIP reports directly to the CDC director, with management and support provided by the National Center for Immunization and Respiratory Diseases. Visit the CDC’s ACIP page for updates and meeting information.
What to Watch Next
The outcome of the legal challenge brought by the American Academy of Pediatrics will be a key factor in determining the future of the ACIP and federal vaccination policy. The March meeting, once scheduled, will be closely watched for any further announcements regarding vaccine recommendations and the committee’s direction. The ongoing leadership changes at the CDC also add to the uncertainty surrounding public health initiatives.
