The Advisory Committee on Immunization Practices (ACIP) annually publishes an immunization schedule for persons aged 0 through 18 years that summarizes recommendations for currently licensed vaccines for children aged 18 years and younger and includes recommendations in effect as of December 15, 2009. The changes to the previous schedule are presented in this guide. The National Childhood Vaccine Injury Act requires that health-care providers provide parents or patients with copies of Vaccine Information Statements before administering each dose of the vaccines listed in the schedules.
