Confusion erupted after a member of the CDC’s Advisory Committee on Immunization Practices claimed the panel had been "disbanded" following a federal judge’s temporary injunction that blocked recent appointments and votes. The assertion was quickly refuted by others, but the episode underscores legal and political uncertainty surrounding ACIP after Health Secretary Robert F. Kennedy Jr. replaced the prior expert panel. The injunction followed a lawsuit by medical groups including the American Academy of Pediatrics challenging the new appointments and the process by which vaccine recommendations were altered. Public‑health experts warn the dispute risks undermining confidence in ACIP’s guidance and could delay evidence‑based vaccine policymaking.
