Which organization issues the vaccine schedule on an annual basis?

• A. Advisory Committee on Immunization Practices
• B. American Academy of Pediatrics
• C. World Health Organization
• D. Centers for Disease Control and Prevention

Answer: (A)

The key idea is that a specialized panel reviews vaccines and issues updated recommendations each year, which then become the official schedule. This Advisory Committee on Immunization Practices brings together experts to evaluate safety, effectiveness, and dosing, and its updated guidance is published annually as the US immunization schedule by the CDC. The World Health Organization provides global guidelines, not the U.S. schedule; the American Academy of Pediatrics offers clinical guidance but does not set the official schedule; and while the CDC publishes the schedule, it does so based on ACIP recommendations. So the organization that issues the annual schedule is the Advisory Committee on Immunization Practices.
