This schedule includes recommendations in effect as of January 1, 2017. Any dose not administered at the
recommended age should be administered at a subsequent visit, when indicated and feasible. The use of a
combination vaccine generally is preferred over separate injections of its equivalent component vaccines.
Vaccination providers should consult the relevant Advisory Committee on Immunization Practices (ACIP) statement
for detailed recommendations, available online at www.cdc.gov/vaccines/hcp/acip-recs/index.html. Clinically
significant adverse events that follow vaccination should be reported to the Vaccine Adverse Event Reporting
System (VAERS) online (www.vaers.hhs.gov) or by telephone (800-822-7967). Suspected cases of vaccinepreventable
diseases should be reported to the state or local health department. Additional information, including
precautions and contraindications for vaccination, is available from CDC online (www.cdc.gov/vaccines/hcp/admin/contraindications.html) or by telephone (800-CDC-INFO [800-232-4636]).
