*For MMR, Varicella, and Hepatitis A vaccines, the first dose must be given on or after the first birthday.

**A complete Hib series is two doses plus a booster dose on or after 12 months of age (three doses total). If a child receives the first dose of Hib vaccine at 12-14 months of age, only one additional dose is required (two doses total). Any child who has received a single dose of Hib vaccine on or after 15 months of age is in compliance with these specified vaccine requirements.

***If the PCV series is started when a child is seven months of age or older, then all four doses are not required.

• For children seven through 11 months of age, two doses are required.

• For children 12-23 months of age: if three doses have been received prior to 12 months of age, then an additional dose is required (total of four doses) on or after 12 months of age. If one or two doses were received prior to 12 months of age, then a total of three doses are required with at least one dose on or after 12 months of age. If zero doses have been received, then two doses are required with both doses on or after 12 months of age.

• Children 24 months through 59 months meet the requirement if they have at least three doses with one dose on or after 12 months of age, or two doses with both doses on or after 12 months of age, or one dose on or after 24 months of age. Otherwise, one additional dose is required.
