The US Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices, or ACIP, will gather this week for its second regular meeting of the year, but this won’t be a typical meeting.

A leader of the CDC's reconstituted vaccine advisory committee said the panel would start a review of long-approved shots.

New members of the ACIP panel raised questions about the evidence supporting COVID vaccines, and signaled plans to look at other established shots, like those for measles and hepatitis B.
