On January 5, 2026, the Department of Health and Human Services (HHS) announced significant changes to the U.S. childhood immunization schedule, reducing universal vaccine recommendations from 18 to 11 diseases and introducing three categories: Routine (Universal), High-Risk Based, and Shared Clinical Decision-Making (SCDM).

Six vaccines were moved from Universal to SCDM status: Rotavirus, COVID-19, Influenza, Hepatitis A, Hepatitis B, and Meningococcal. Under SCDM, vaccination decisions are made between the doctor and patient/family based on individual health history and risk profile — not a universal age-based requirement.

Important context: These changes were implemented outside the standard ACIP public review process. The American Academy of Pediatrics (AAP), the Infectious Diseases Society of America (IDSA), and over 200 health organizations have stated they continue to recommend all six vaccines for all children at the appropriate age. More than 20 states continue to follow the prior CDC or AAP schedule. Insurance coverage for SCDM vaccines remains required under existing federal law.
