HHS Secretary Robert F. Kennedy Jr. has sparked controversy by replacing all members of the CDC's vaccine advisory committee (ACIP) with new appointees, some of whom have expressed vaccine skepticism. This follows Kennedy's prior anti-vaccine stances and his past leadership of the Children's Health Defense, an anti-vaccine group. Concerns are rising among public health professionals about potential reductions in vaccine access and the lack of transparency in the ACIP's reconstitution. The new ACIP will vote on vaccine recommendations, including for the fall and for children, sparking debate over the future of vaccine policy in the US.
