Who decides the immunization schedule?

Each year, the Advisory Committee on Immunization Practices (ACIP) publishes immunization schedules for children, preteens and teens. These schedules summarize recommendations for routine vaccines for children age 18 years and younger. The recommended immunization schedules are approved by the Advisory Committee on Immunization Practices (ACIP), the American Academy of Pediatrics (AAP), the American Academy of Family Physicians (AAFP), and the American College of Obstetricians and Gynecologists (ACOG).
