The Recommended Childhood Immunization Schedule United States, July—December 1996 was developed by the Committee on Infectious Diseases of the American Academy of Pediatrics in collaboration with the Advisory Committee on Immunization Practices (ACIP) of the Centers for Disease Control and Prevention, and the American Academy of Family Physicians. Since the Schedule was last published in January 1996, no new vaccines have been approved by the Food and Drug Administration and as of May 15, 1996, no changes had been made in Academy recommendations.1 If additional changes are made before the next publication in the January 1997 issue of Pediatrics, the membership will be informed through other channels. For detailed information on the use of vaccines, providers should refer to the l994 Red Book: Report of the Committee on Infectious Diseases,2 the ACIP General Recommendations on Immunization3 and the vaccine package inserts.
