CDC Cuts the Childhood Vaccine Schedule From 17 Diseases to 11

On January 5, 2026, the Centers for Disease Control and Prevention, acting on a presidential memorandum, narrowed the routine childhood immunization schedule from 17 diseases to 11. Acting CDC director Jim O'Neill announced the change. Measles, polio and pertussis vaccines remain routine; the RSV immunization was restricted to high-risk infants, and rotavirus, influenza and hepatitis A shots were moved to a category requiring a conversation with a provider first.

Routine schedule recommendations drive insurance coverage requirements, Vaccines for Children eligibility, school entry rules and pharmacy protocols. Public health specialists noted the revision did not go through the Advisory Committee on Immunization Practices, the body that has historically supplied the scientific record for such changes. Senator Bill Cassidy, a Republican physician, said altering the pediatric schedule "based on no scientific input on safety risks and little transparency will cause unnecessary fear."

The revised schedule took effect as announced. Medical organizations criticized the timing during respiratory season, and members of Congress asked Health Secretary Robert F. Kennedy Jr. to restore the prior schedule.
