Important Notes

Combination Vaccines

Many vaccines can be given as combination products (e.g., DTaP-IPV-HepB, MMRV) to reduce the number of injections needed.

Catch-up Schedules

Children who miss doses can catch up. Consult CDC catch-up schedule for appropriate intervals and timing.

Special Populations

Immunocompromised patients, pregnant women, and healthcare workers may have different recommendations.

Travel Vaccines

Additional vaccines (yellow fever, typhoid, Japanese encephalitis) may be needed for international travel.
