An upcoming meeting of vaccine advisers to the Centers for Disease Control and Prevention has been postponed, delaying what was set to be the committee’s first gathering after the swearing-in of Robert F. Kennedy Jr. as U.S. health secretary.

The Advisory Committee on Immunization Practices was scheduled to meet Feb. 26 to Feb. 28 to discuss vaccines for respiratory syncytial virus, meningococcal disease and human papillomavirus. The meeting is now “postponed to accommodate public comment in advance of the meeting,” according to Andrew Nixon, the director of communications for the Department of Health and Human Services, which oversees the CDC.

“The ACIP workgroups met as scheduled this month and will present at the upcoming ACIP meeting,” Nixon added in an email.

ACIP convenes regularly throughout the year to discuss emerging safety and efficacy data on vaccines, and to develop recommendations that are then formalized by the CDC. The February meeting has been on the calendar since at least last October, according to older webpages saved by Internet Archive.

In winning congressional confirmation, Kennedy promised Sen. Bill Cassidy, R-La., a physician who admitted to “struggling” with Kennedy’s history of anti-vaccine views, that he’d maintain ACIP without change, as well as “work within” existing vaccine approval and safety frameworks.

Cassidy’s office did not respond to BioPharma Dive’s request for comment.

Kennedy, who previously sought to restrict vaccination in the U.S. through lawsuits and work with the group Children’s Health Defense, has signaled his intentions to shake up HHS agencies. According to reporting by Politico, he’s considering whether to remove members of panels like ACIP that advise the government on vaccines if he finds conflicts of interest. The HHS secretary oversees ACIP and can select its members.

Politico also noted how the online portal for public comments ahead of ACIP’s meeting next was never activated, which apparently contributed to the decision to postpone.
