Recommended childhood and adolescent immunization schedule. United States, 2003. Centers for Disease Control and Prevention.

Each year, CDC's Advisory Committee on Immunization Practices (ACIP) reviews the recommended childhood and adolescent immunization schedule to ensure that it is current with changes in manufacturers' vaccine formulations and contains revised recommendations for the use of licensed vaccines, including those newly licensed. The recommended childhood immunization schedule for 2003 has remained the same in content and format since January 2002 (Figure 1). The recommendations and format have been approved by ACIP, the American Academy of Family Physicians, and the American Academy of Pediatrics.
