Secretary Robert F. Kennedy Jr. said Monday he is “reviewing” whether to remove all members of an influential advisory committee that offers guidance about preventive health services. The U.S. Preventive Services Task Force is composed of medical experts who serve four-year terms on a volunteer basis.

All 17 experts from the Advisory Committee for Immunization Practices who were replaced last month by Robert F. Kennedy Jr. called the health secretary's new picks "inexperienced and biased."

In early June, Kennedy dismissed all 17 sitting members of the Advisory Committee on Immunization Practices (ACIP), which advises the Centers for Disease Control and Prevention (CDC) on vaccine recommendations.
