Politicized science appointments
Politicized science appointments are the installation of unqualified or ideologically selected individuals into scientific, statistical, or technical roles that require domain expertise — agency chief scientists, advisory committee members, statistical office leadership. Concrete forms include the replacement of career experts with political appointees lacking relevant credentials, the stacking of advisory committees with members holding minority views inconsistent with the field's consensus, and the bypassing of standard credentialing for politically aligned candidates.

RFK Jr.-appointed ACIP panel voted 8-3 to delay routine MMRV childhood vaccine, first change to immunization schedule
On September 18, 2025, the Advisory Committee on Immunization Practices — its entire prior membership of 17 independent scientific experts having been dismissed and replaced by HHS Secretary Robert F. Kennedy Jr. — voted 8-3 to delay routine administration of the MMRV combination vaccine (measles, mumps, rubella, and varicella) from the standard 12–15 months to age 4. It was the first change to the childhood immunization schedule under Kennedy's HHS and the first ACIP meeting of his hand-picked panel, which observers and STAT News described as "rocky" amid procedural irregularities, complaints about insufficient review time, and a postponed hepatitis B vote.
HHS Secretary Kennedy dismissed all 17 ACIP members and replaced them with political selections
On June 9, 2025, HHS Secretary Robert F. Kennedy Jr. dismissed all 17 sitting members of the Advisory Committee on Immunization Practices via a press release and a simultaneous Wall Street Journal op-ed, characterizing them as conflicted and as last-minute Biden appointees. ACIP is the independent federal advisory body whose vaccine recommendations are adopted by the CDC and followed by pediatricians and public health agencies nationwide. Kennedy announced eight replacement members on June 11, 2025; the replacement panel, described by observers as less credentialed than its predecessor, voted 8-3 at its inaugural September 2025 meeting to delay routine administration of the MMRV childhood vaccine — the first change to the immunization schedule under Kennedy's HHS.
