Past Immunization Schedules
If you wish to see the how the schedules have changed over the years in general, use the links listed below. Within each MMWR you should find a section detailing what exactly changed since the prior year's schedule.
Beginning in 1995, a "harmonized" childhood schedule, approved by the Advisory Committee on Immunization Practices (ACIP), the American Academy of Pediatrics (AAP), and the American Academy of Family Physicians (AAFP) has been published annually.
Prior to 1995, the childhood schedule was published periodically, as part of the ACIP's General Recommendations.
