U.S. Secretary of Health and Human Services Robert F. Kennedy Jr. earlier this month fired the members of the Advisory Committee on Immunization Practices, some of whom were barely into their appointed terms. The new panel, appointed two weeks ago, includes a number of people known to be vaccine skeptics or “anti-vaccination.”

The Center for Disease Control and Prevention’s Advisory Committee on Immunization Practices (ACIP), and its eight new members, met for the first time Thursday after Health and Humans Services Secretary Robert F. Kennedy, Jr. announced a “clean sweep” of the panel earlier this month.
