Each year, the Advisory Committee on Immunization Practices (ACIP) reviews the recommended immunization schedules for persons aged 0 through 18 years to ensure that the schedules reflect current recommendations for Food and Drug Administration-licensed vaccines. In October 2013, ACIP approved the recommended immunization schedules for persons aged 0 through 18 years for 2014, which include several changes from the 2013 immunization schedules.
