CDC's Advisory Committee on Immunization Practices (ACIP) periodically
reviews the recommended childhood and adolescent immunization schedule to
ensure that the schedule is current with changes in manufacturers' vaccine
formulations and reflects revised recommendations for the use of licensed
vaccines, including those newly licensed. Recommendations and format of the
childhood and adolescent immunization schedule for January–June 2004
were approved by ACIP, the American Academy of Family Physicians (AAFP), and
the American Academy of Pediatrics (AAP) and published in January 2004.1 This report updates that schedule with the recommendation that, beginning
in fall 2004, children aged 6–23 months, as well as household and out-of-home
caregivers for such children, receive annual influenza vaccine.2 This
change is reflected in the revised childhood and adolescent immunization schedule
for July–December 2004 (Figure 1).
A catch-up immunization schedule for children and adolescents who start late
or who are >1 month behind remains unchanged from that published in January
2004 (Table 1).
