Tension erupted around the CDC’s vaccine advisory committee after a federal judge issued a temporary injunction challenging recent appointments; an ACIP member publicly claimed the panel had been disbanded, then retracted the statement. The dispute stems from Health Secretary Robert F. Kennedy Jr.’s replacement of longtime ACIP experts with members critics say lack vaccine specialty experience. The legal challenge, brought by pediatric and medical societies, prompted an injunction that blocked the new members’ votes, and uncertainty now surrounds ACIP’s composition and the federal vaccine recommendation process.
