Health Secretary Robert F. Kennedy Jr. has significantly altered the charter for a federal vaccine advisory panel. These changes grant him greater authority to appoint like-minded advisors, redirect the panel's focus toward alleged vaccine injuries and risks, and open the door to fringe and anti-vaccine organizations at the Centers for Disease Control and Prevention.

The revised charter for the Advisory Committee on Immunization Practices (ACIP) introduces new responsibilities, including the analysis of cumulative effects of vaccines and their components. This language aligns with goals of anti-vaccine activists who seek to link complex conditions to vaccine combinations or ingredients like aluminum adjuvants.

The charter also explicitly tasks ACIP with monitoring mRNA vaccines, a technology particularly criticized by Kennedy.
