Health and Human Services Secretary Robert F. Kennedy Jr. announced Monday that he is dismissing all 17 members of the Advisory Committee on Immunization Practices (ACIP), a key panel that guides national vaccine policy.

Staff who provide data to the vaccine panel have been pushed aside, according to health officials, raising doubts about the availability of coronavirus and other vaccines.

It plays a big role in deciding which vaccines kids and adults get routinely, what’s covered by insurance and which shots are made available free to low-income kids.
