GOP Sen. Bill Cassidy said a vaccine advisory panel should delay its next meeting and raised questions about potential bias of RFK-appointed members.

Health and Human Services Secretary Robert F. Kennedy Jr. on Tuesday denied agreeing not to make changes to a key Centers for Disease Control and Prevention vaccine safety panel, which has caused a significant stir in the public health community.

Sen. Bill Cassidy called for a meeting of a Centers for Disease Control and Prevention vaccine advisory committee set for this week to be postponed, citing a lack of experience among its new appointees.
