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.

Republican Sen. Bill Cassidy on Monday night called for federal health officials to postpone this week’s meetings of outside vaccine advisers, citing a small, newly appointed panel and concerns about biases against vaccines.

The Centers for Disease Control and Prevention's vaccine advisory committee is set to meet for the first time since Health and Human Services Secretary Robert F. Kennedy Jr. dismissed the entire panel and appointed his own hand-selected members.
