The Advisory Committee on Immunization Practices (ACIP), recently reshaped by Health Secretary Robert F. Kennedy Jr., held its first meeting marking a significant shift in vaccine oversight. The new panel, composed partly of members with anti-vaccine views, announced plans to reassess the entire childhood vaccination schedule alongside adult vaccines. This overhaul has triggered criticism from public health organizations, which question the panel’s credibility and scientific rigor. The developments pose challenges for established vaccine policy-making and public confidence in immunization programs.
