Immunizations for Infants and Young Children
Birth-6 Years Old
Is your child up to date on his or her immunizations?
Parents work hard to keep their babies healthy and safe. Even healthy babies can get sick and need vaccines to protect them from serious diseases. Infants need immunizations at birth, 2, 4, 6, and 12-15 months of age. By vaccinating your child according to immunization guidelines, parents can protect their babies from 14 serious diseases before they turn 2. Young children will need additional vaccines up to age 6. See vaccine information below to learn about which vaccines your child should get at which age.
