# ACIP
The Advisory Committee on Immunization Practices is the [[CDC]] advisory body whose recommendations set the US immunization schedule — and, through the Vaccines for Children program and the ACA's no-cost-sharing rules, determine what vaccines insurers must cover for free. That coverage linkage is why capturing ACIP became the [[MAHA]] movement's single highest-leverage move.
## The purge and reconstitution
On June 9, 2025, HHS Secretary [[Robert F. Kennedy Jr]] fired all 17 sitting members; two days later he named 8 replacements, including prominent vaccine critics — Robert Malone became vice chair, alongside MIT's Retsef Levi and Great Barrington Declaration co-author Martin Kulldorff — and added five more in September 2025. Under Senate questioning in April 2026, Kennedy acknowledged that Trump and senior White House officials personally signed off on the firings.
## What the new panel did
The reconstituted committee moved fast: a June 2025 vote to drop thimerosal from flu vaccines; September 2025 votes restricting MMRV for under-4s and downgrading COVID-19 vaccination from routine recommendation to "shared clinical decision-making"; and in December 2025, an 8–3 vote ending the universal hepatitis-B birth dose (adopted by CDC December 16), which the American Academy of Pediatrics called "heartbreaking."
## The court fight
The AAP and allied groups sued. On March 16, 2026, US District Judge Brian Murphy ruled the changes arbitrary and capricious, found 13 Kennedy appointees "appear distinctly unqualified," stayed their appointments, and blocked the panel's actions — including the revised schedule and the hepatitis-B downgrade. CDC canceled subsequent ACIP meetings; as of July 2026 the appointments remain on hold, the administration is expected to appeal, and an April 2026 HHS rewrite of ACIP's charter has critics warning of a second capture attempt.
## Downstream workarounds
Insurers committed to covering pre-September-2025 recommendations without cost-sharing through 2026. The West Coast Health Alliance (CA/OR/WA/HI) now recommends vaccines per the AAP's independent schedule — California's AB 144 effectively decoupled the state from ACIP — a live example of blue-state institutional forking in response to federal capture.
## Bypassed by executive order (August 2026)
Litigation over the reconstituted committee's composition stalled the administration's vaccine-schedule directives — and [[Executive Order 14420]] of August 10, 2026 says so on its face, citing "litigation over the composition of the Advisory Committee on Immunization Practices" as the reason for further action. The order then declares the recommendations directly by presidential fiat, routing around the committee entirely.
The significance for ACIP as an institution is that its capture became unnecessary. Contesting the committee's membership in court was slower than replacing its function, so the administration did the latter. A body whose recommendations can be superseded by executive order is no longer the chokepoint it was built to be.
