ACIP vote follows two postponements and contentious meeting and comes as RFK Jr pushes for vaccine delay

After a delay and an unusually contentious meeting, a federal vaccine advisory panel was expected to vote on Friday whether to change the longstanding recommendation that all newborns be immunized against hepatitis B.

The first day of the meeting of the advisory committee on immunization practices (ACIP) on Thursday was marked by heated debate over restricting access to the hepatitis B vaccine for infants and a decision to defer the vote by a day to give members more time to review the wording. The panel, which advises the Centers for Disease Control and Prevention (CDC) on how to use vaccines, had twice before postponed the vote.
