Robert F. Kennedy Jr., the Health Secretary with an anti-vaccine stance, has modified the charter of the Advisory Committee on Immunization Practices (ACIP) to grant himself greater authority in selecting committee members. This change comes after a federal judge, Brian Murphy, temporarily blocked Kennedy's previous appointments, citing that they lacked the necessary expertise and did not represent a balanced view within the scientific community. The judge's ruling also halted all ACIP activities and reversed recent policy changes that eliminated recommendations for COVID-19 vaccines and the Hepatitis B birth dose, both of which faced criticism from public health organizations. The new charter, published in the Federal Register, allows Kennedy to unilaterally appoint members, a significant shift from past practices where appointments were more regulated. This amendment reflects Kennedy's ongoing efforts to reshape the committee in alignment with his views.
