Immunization Schedule Information

There are different vaccine schedules for infants, adults, children, college students, pregnant women and other groups. These schedules are developed based on recommendations of the Advisory Committee on Immunization Practices (ACIP). The Advisory Committee on Immunization Practices (ACIP) is a group of medical and public health experts that develops recommendations on how to use vaccines to control diseases in the United States.


ACIP members have been selected by the Secretary of the U. S. Department of Health and Human Services. Fourteen of the members have expertise in vaccinology, immunology, pediatrics, internal medicine, nursing, family medicine, virology, public health, infectious diseases, and/or preventive medicine; one member is a consumer representative who provides perspectives on the social and community aspects of vaccination. The Committee develops vaccine recommendations for children and adults, which includes the age(s) each vaccine should be given, number of doses and spacing between doses, and any precautions and contraindications that clinicians should follow.

The schedules are reviewed annually to help ensure the best and safest administration of vaccines for you and your family. If you are considering following an alternative dosing schedule, please keep in mind that no alternative schedule has been released or approved by the ACIP or any other professional organization.
