The U.S. Centers for Disease Control and Prevention (CDC) will convene its vaccine advisory committee on June 25–26 for the first time since the panel was dissolved and reconstituted by Health Secretary Robert F. Kennedy Jr.—a controversial move that introduced several members known for their opposition to certain vaccines.
The reconstituted Advisory Committee on Immunization Practices (ACIP) is expected to deliberate on updated data and vote on multiple vaccine-related matters, including influenza, respiratory syncytial virus (RSV), and the use of thimerosal—a mercury-based preservative historically used in some multi-dose vaccine vials.
