RFK Jr. Expands CDC Vaccine Advisory Panel's Scope Amid Legal Battles

U.S. Health Secretary Robert F. Kennedy Jr. has signed a new charter for the CDC's Advisory Committee on Immunization Practices (ACIP), broadening the panel's focus to include vaccine risks and alleged gaps in vaccine safety research. The charter, signed on March 31 and publicly posted shortly after, comes following a federal court ruling that challenged the legitimacy of Kennedy's previously reconstituted vaccine panel.

Last month, Boston-based U.S. District Judge Brian Murphy ruled that ACIP had been unlawfully restructured after Kennedy removed all 17 independent vaccine experts from the panel in 2024, replacing them with individuals who largely share his controversial stance on vaccine safety. The court placed the new panel's decisions on hold, prompting the latest charter revision.

The updated charter expands membership eligibility beyond traditional vaccine research and immunization expertise to now include specialists in toxicology, data science, and vaccine safety assessment. Critics argue the revised language — replacing stricter qualifications with the broader term "knowledgeable" — lowers the bar for panel membership and could make future legal challenges more difficult to sustain. Dorit Reiss, a vaccine policy law professor at UC Law San Francisco, raised this concern publicly.

The new charter also adds four non-voting liaison organizations, three of which — the Association of American Physicians and Surgeons, the Independent Medical Alliance, and Physicians for Informed Consent — have publicly expressed anti-vaccine positions. A fourth group, the Medical Academy of Pediatrics and Special Needs, advocates for children with autism, a condition Kennedy has repeatedly and falsely linked to childhood vaccines despite overwhelming scientific consensus to the contrary.

An HHS spokesperson described the charter renewal as routine and denied it signals any broader policy change. However, former CDC official Daniel Jernigan warned the move further politicizes vaccine guidance, while the American Academy of Pediatrics has not ruled out a legal challenge to the restructured panel.
