The White House said CDC and ACIP would realign the childhood vaccine schedule with peer countries. After EO 14420 §1 cited delay over ACIP’s composition, the President declared the schedule himself
A December 5, 2025 presidential memorandum told HHS and CDC to study peer-country childhood immunization practices and, if those practices were superior, update the U.S. schedule while preserving access. EO 14407 §2(c) (May 29, 2026) locked no-cost-sharing coverage for any ACIP/CDC category; EO 14420 does not repeal that lock. EO 14420 §1 (August 10, 2026) cited delay due to litigation over ACIP’s composition — no case is named here — then §2(a)(i) declared an 11-disease universal list, with hepatitis A and hepatitis B in both §2(a)(ii) and §2(a)(iii).
