A top COVID-19 vaccine advisor has reportedly resigned from her role at the Centers for Disease Control and Prevention in the wake of an abrupt vaccine policy change announced by Robert F. Kennedy Jr.

Kennedy also gleefully said he was revoking recommendations for vaccinating healthy children. But the CDC's edited immunization schedule did not remove the recommendation outright; rather, it simply added a stipulation that a child's doctor and parents agree on the vaccination, described as "shared clinical decision-making."
