CDC Cancels Its Vaccine Advisers' October Meeting, the Third Called Off This Year. Here Is What Stays in Force.
The Advisory Committee on Immunization Practices has not met since a federal judge blocked 13 of its members in March. A federal appeals court heard the government's appeal on Oct. 6 and has not ruled.
The Centers for Disease Control and Prevention has cancelled the October meeting of its Advisory Committee on Immunization Practices (ACIP). The ACIP meetings page, updated Oct. 9, lists the Oct. 21 to 23 session with the note "Due to ongoing litigation, this meeting is cancelled." The committee's March and June 2026 meetings carry the same note. The next dates on the page are Feb. 24 to 26, 2027.
That leaves the committee without a meeting for the whole of 2026. For clinicians, the practical question is which recommendations are in force this respiratory season and what cannot change until the case is resolved.
How the committee got here
Health Secretary Robert F. Kennedy Jr. removed all 17 members of ACIP last year and replaced them. The American Academy of Pediatrics and other medical groups sued. On March 16, U.S. District Judge Brian Murphy in Massachusetts found that the appointments did not comply with the Federal Advisory Committee Act and blocked 13 appointees from serving, Reuters reported.
The same order stayed the CDC's January 2026 memo that cut the routine childhood schedule, and set aside the votes the reconstituted committee had taken since June 2025. CIDRAP's summary of the ruling lists among them the removal of the universal hepatitis B birth dose and the downgrade of COVID-19 vaccination to shared clinical decision-making. The administration did not appeal those parts. It appealed only the block on the appointees, arguing that the order leaves ACIP without the quorum it needs to act.
Where the appeal stands
A panel of the 1st U.S. Circuit Court of Appeals in Boston, Chief Judge David Barron and Judges William Kayatta and Joshua Dunlap, heard argument in American Academy of Pediatrics v. Kennedy (No. 26-1503) on Oct. 6. A Justice Department lawyer asked the court to vacate the order so the secretary can reconstitute the committee. Barron questioned why the order did not explain the legal basis for blocking the appointees, according to Reuters, and the plaintiffs' lawyer, Andrew Pincus, urged the court to keep it in place. As of Oct. 15, the public docket showed no decision.
Until the court rules and the committee meets again, the schedules in place before the January changes are the working standard.
What stays in force
The CDC's immunization schedules page still presents the child and adult schedules with addenda dated July 2, 2025, and the child schedule lists a hepatitis B dose at birth. The page does not mention the litigation.
Coverage follows from that. Private plans, Medicaid and the Vaccines for Children program are tied by statute to ACIP recommendations, as KFF has explained. Medicare Part B is different: CMS lists influenza, COVID-19, pneumococcal and hepatitis B as preventive vaccines Part B covers because a statute names them. Separately, the insurer trade group AHIP pledged in September 2025 that member plans would cover all immunizations ACIP recommended as of Sept. 1, 2025, including updated COVID-19 and flu formulations, with no cost-sharing through the end of 2026.
What cannot move
Without a meeting, there is no federal route for a new vaccine or a new indication to gain an ACIP recommendation, and the coverage requirements that depend on one. The AHIP pledge also runs out at the end of 2026, before the next scheduled meeting in February.
Flu activity is already rising on the West Coast, as we reported this week, and the existing seasonal flu recommendation, annual vaccination for everyone 6 months and older, is unaffected by the dispute.
What to do this week
Ask your billing office whether any payer has issued notices citing ACIP status, and keep the hepatitis B birth dose and COVID-19 orders in line with the posted schedules. Pick one reference, the CDC schedule or your specialty society's, and use it consistently in handouts and reminder messages. If a patient asks why guidance looks unsettled, explain that the court fight is over who sits on the committee, and that the existing schedule still applies.
