Overview

• On June 9, 2025, HHS Secretary Robert F. Kennedy Jr. retired all 17 Biden-appointed members of the CDC’s Advisory Committee on Immunization Practices, citing conflict-of-interest concerns.
• Kennedy characterized the panel as a “rubber stamp” for vaccines and said a complete reconstitution was needed to restore public trust in vaccine science.
• The ACIP is set to reconvene June 25–27 in Atlanta with a new slate of members yet to be announced.
• Major medical organizations and former CDC officials say the move undermines decades of transparent, science-based vaccine guidance and risks public health.
• Senator Bill Cassidy expressed fear that the replacement process could favor appointees driven by vaccine skepticism rather than expertise.
