Health Secretary Robert F. Kennedy Jr. dismissed all 17 members of the CDC’s Advisory Committee on Immunization Practices (ACIP), triggering backlash from medical organizations including the AMA and ACP, which called for Senate investigation. The administration stated this overhaul aims to restore public confidence by appointing members less influenced by industry, though critics warn this threatens evidence-based vaccine recommendations. The upheaval accompanies ongoing tensions around vaccine policy and politicization, potentially impacting public health decision-making and vaccine access.
