Child Vaccine Schedule

The following is the routine childhood vaccine (immunization) schedule from the CDC. There is also a catch-up schedule for children who are behind on vaccines, and a different schedule and some other vaccines for children considered high-risk for infection. Your child's healthcare provider or nurse can give you information about the routine and other schedules. Your provider will also let you know which vaccines can be given on a different schedule than listed below. For instance, the vaccines for 2-month-olds may be given as early as age 6 weeks. Your provider will discuss this with you.
