The 17 members of the CDC's vaccine advisory committee, who were ousted last week, argued their abrupt dismissal has "left the U.S. vaccine program critically weakened."

Kennedy last week announced he would "retire" the entire panel that guides U.S. vaccine policy. He also quietly removed Dr. Melinda Wharton — the veteran Centers for Disease Control and Prevention official who coordinated the committee's meetings.

Seventeen vaccine experts who were dismissed from a federal advisory panel last week say they are worried that recent moves by US Health and Human Services Secretary Robert F. Kennedy Jr. will destabilize vaccine policy in the US and jeopardize access to lifesaving immunizations.
