Summary

On June 9, 2025, Robert F. Kennedy Jr., the Secretary of Health and Human Services (HHS), dismissed all 17 members of the CDC’s Advisory Committee on Immunization Practices (ACIP). Secretary Kennedy claimed the move was necessary to eliminate “conflicts of interest” and restore public trust in vaccines, which he argued had been compromised by the influence of pharmaceutical companies. However, this decision strays from precedent and has drawn significant criticism from medical experts and public health officials across the country. Some argue that this shake-up undermines scientific independence and opens the door to politicized decision-making in vaccine policy.

Background: What Is ACIP?

The Advisory Committee on Immunization Practices (ACIP) is a federal advisory group that helps guide national vaccine policy. Established in 1964, it has over 60 years of credibility as an evidence-based body of medical and scientific experts. ACIP makes official recommendations on vaccine schedules for both children and adults, determining which immunizations are required for school entry, covered by health insurance, and prioritized in public health programs. The committee is composed of specialists in immunology, epidemiology, pediatrics, infectious disease, and public health, all of whom are vetted for scientific rigor and ethical standards. ACIP’s guidance holds national weight, shaping both public perception of vaccines and the policies of institutions like schools, hospitals, and insurers.
