Kennedy’s decision to “retire” the previous 17-member panel was widely decried by doctors’ groups and public health organizations, who feared the advisers would be replaced by a group aligned with Kennedy’s desire to reassess — and possibly end — longstanding vaccination recommendations.

The announcement of the new members of the CDC Advisory Committee on Immunization Practice comes days after the HHS secretary removed all previous members of the panel.

Anti-vaccine advocate and current Health Secretary Robert F. Kennedy Jr. took to social media Wednesday to announce the names of eight people he is appointing to a critical federal vaccine advisory committee—which is currently empty after Kennedy abruptly fired all 17 previous members Monday.
