Multiple medical groups say they have been barred from working on the Centers for Disease Control and Prevention's panel of vaccine advisers.

The reshaping of the CDC's vaccine advisory panel has continued, with the apparent barring of reps of medical associations from ACIP work groups.

Multiple healthcare organizations that have historically helped the CDC's Advisory Committee on Immunization Practices (ACIP) develop vaccine recommendations have been told they can no longer participate in ACIP work groups, leaving the organizations frustrated and worried about what will happen next.
