2021 Recommended Vaccinations for Infants and Children (birth through 6 years)

2021 Baby Vaccine Schedule

Vaccination is one of the best ways parents can protect infants, children, and teens from 16 potentially harmful diseases that can be very serious, may require hospitalization, or even be deadly.
And immunizations are not just for children. Protection from some childhood vaccines can wear off over time. Adults may also be at risk for vaccine-preventable disease due to age, job, lifestyle, travel, or health conditions.

Note: If your child misses a shot, you don’t need to start over. Just go back to your child’s doctor for the next shot. Talk with your child’s doctor if you have questions about vaccines.


*Two doses given at least four weeks apart are recommended for children age 6 months through 8 years of age who are getting an influenza (flu) vaccine for the first time and for some other children in this age group.

**Two doses of HepA vaccine are needed for lasting protection. The first dose of HepA vaccine should be given between 12 months and 23 months of age. The second dose should be given 6 months after the first dose. All children and adolescents over 24 months of age who have not been vaccinated should also receive 2 doses of HepA vaccine.
