Advisory Committee on Immunization Practices (ACIP) Meeting Cancellation – March 2026
AI-generated summary for informational purposes only. Not legal advice. See the original source for the authoritative text.
The U.S. Department of Health and Human Services has issued a public notice announcing the cancellation and stay of the Advisory Committee on Immunization Practices (ACIP) meeting that was scheduled for March 18–19, 2026. The stay was ordered by a federal court pursuant to a preliminary injunction issued on March 16, 2026, in the case American Academy of Pediatrics et al. v. Kennedy et al., Case No. 1:25-cv-11916, filed in the U.S. District Court for the District of Massachusetts. The ACIP is a federal advisory body that makes vaccine schedule recommendations to the Centers for Disease Control and Prevention (CDC). Its meetings are significant public health events where new vaccine approvals, schedule updates, and immunization policy guidance are reviewed and voted upon. The court-ordered stay halts the meeting indefinitely — 'until further notice' — meaning no new immunization recommendations or votes can be made by ACIP until the court lifts the injunction or the case is resolved. The underlying lawsuit appears to challenge actions by Secretary Kennedy or the HHS administration regarding immunization policy.
