At its October 2019 meeting, the Advisory Committee on Immunization Practices (ACIP)* voted to recommend approval of the 2020 Recommended U.S. Adult Immunization Schedule for Persons Aged 19 Years and Older. The 2020 adult immunization schedule, available at https://www.cdc.gov/vaccines/schedules/index.html,† summarizes ACIP recommendations in two tables and accompanying notes. This 2020 adult immunization schedule has been approved by the CDC Director, the American College of Physicians, the American Academy of Family Physicians, the American College of Obstetricians and Gynecologists, and the American College of Nurse-Midwives. Health care providers are advised to use the tables and the notes together.
