U.S. Health Secretary Robert F. Kennedy Jr. has issued a new charter for the CDC's vaccine advisory committee, the Advisory Committee on Immunization Practices (ACIP), that expands the panel's role to include a focus on vaccine risks and perceived gaps in vaccine safety evidence. The move comes after a federal court ruling that declared most prior ACIP members unqualified, putting their decisions on hold.

Why it matters

The ACIP is a key advisory body that makes recommendations impacting the use and insurance coverage of vaccines, including the U.S. childhood immunization schedule. Kennedy's changes to the panel's membership and mandate raise concerns about the politicization of vaccine policy and potential undermining of scientific consensus on vaccine safety.

The details

The new charter broadens the membership criteria beyond those with expertise in vaccine use and research, specifically adding toxicology, data science, and 'expertise in the assessment of vaccine safety and efficacy.' It also names four new organizations to serve as non-voting liaisons to the committee, including groups that have expressed anti-vaccine views. Experts say the changes weaken the expertise requirement and make it easier to reconstitute the committee with members who share Kennedy's controversial vaccine views.

  • On March 16, a federal judge ruled that ACIP had been unlawfully reconstituted after Kennedy removed all 17 independent experts who previously served on the panel.
  • On March 31, Kennedy signed the new ACIP charter.
  • On April 9, the new charter was posted and announced publicly.

What they’re saying

“The new charter weakens the expertise requirement, requiring members to be 'knowledgeable,' which could make it harder for judges to demand expertise.”

— Dorit Reiss, Professor of law at UC Law San Francisco

“The ACIP charter renewal and its publication 'are routine statutory requirements and do not signal any broader policy shift.'”

— Andrew Nixon, HHS spokesman

“The new charter will make it easier to reconstitute the committee and 'further politicizes the discussion at the meeting.'”

— Daniel Jernigan, Former director of the CDC's National Center for Emerging and Zoonotic Infectious Diseases

What’s next

It remains to be seen how the ACIP committee will be reconstituted under the new charter, and whether the American Academy of Pediatrics will challenge the changes.

The takeaway

Kennedy's moves to reshape the ACIP's membership and mandate raise concerns about the politicization of vaccine policy and potential undermining of scientific consensus on vaccine safety, which could have far-reaching impacts on public health.
