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

Several adult vaccines were moved from Universal to SCDM status, including COVID-19, Influenza, Hepatitis A, Hepatitis B, and Meningococcal. Under SCDM, vaccination decisions are made between the doctor and patient 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 affected vaccines for appropriate adult patients. Insurance coverage for SCDM vaccines remains required under existing federal law.
