The Advisory Committee on Immunization Practices (ACIP) has undergone a significant transformation under the appointment of health secretary Robert F. Kennedy Jr., characterized by the replacement of its former members with individuals holding controversial views on vaccines. The newly remade panel has already initiated a comprehensive re-evaluation of the entire childhood vaccination schedule and adult vaccines, including longstanding shots for diseases such as measles and hepatitis B. These developments have triggered strong opposition from professional bodies like the American Academy of Pediatrics, which has refused to participate citing concerns over the panel's credibility and politicization. The panel’s activities signal potential shifts in vaccine policy amid ongoing debates on vaccine safety and efficacy.
