A federal judge in Boston has issued a stay on major elements of Health Secretary Robert F. Kennedy Jr.’s overhaul of U.S. childhood vaccine policy, pausing 13 ACIP appointments and removing the CDC’s revised childhood immunization schedule from immediate effect. The order, issued by U.S. District Judge Brian Murphy, effectively prevents the Advisory Committee on Immunization Practices from meeting while the appointments and procedural steps are under legal review. Medical groups including the American Academy of Pediatrics challenged the administration’s changes, arguing the swap of committee members and the CDC’s reduction of routinely recommended vaccines compromised public-health safeguards and likely violated the Federal Advisory Committee Act. The ruling halts an ACIP meeting that had been scheduled to address COVID-19 vaccine injuries, long COVID, and recommendation methodology, and invites an appeal from HHS.
