1. Tetanus and diphtheria toxoids vaccine (Td) and tetanus and diphtheria toxoids and acellular pertussis vaccine (Tdap).

• Doses of DTaP are counted as part of the Td/Tdap series.

• Tdap should be substituted for a single dose of Td in the catch-up series or as a booster for children aged 10 through 18 years; use Td for other doses.

2. Human papillomavirus vaccine (HPV).

• Administer the series to females at age 13 through 18 years if not previously vaccinated.

• Use recommended routine dosing intervals for series catch-up (i.e., the second and third doses should be administered at 1 to 2 and 6 months after the first dose). The minimum interval between the first and second doses is 4 weeks. The minimum interval between the second and third doses is 12 weeks, and the third dose should be administered at least 24 weeks after the first dose.

3. Hepatitis A vaccine (HepA).

• HepA is recommended for children aged older than 23 months who live in areas where vaccination programs target older children, who are at increased risk for infection, or for whom immunity against hepatitis A is desired.

4. Hepatitis B vaccine (HepB).

• Administer the 3-dose series to those who were not previously vaccinated.

• A 2-dose series(separated by at least 4 months) of adult formulation Recombivax HB® is licensed for children aged 11–15 years.

5. Inactivated poliovirus vaccine (IPV).

• The final dose in the series should be administered on or after the fourth birthday and at least 6 months following the previous dose.

• A fourth dose is not necessary if the third dose was administered at age 4 years or older and at least 6 months following the previous dose.

• In the first 6 months of life, minimum age and minimum intervals are only recommended if the person is at risk for imminent exposure to circulating poliovirus (i.e., travel to a polio-endemic region or during an outbreak).

6. Measles, mumps, and rubella vaccine (MMR).

• Administer the second dose routinely at age 4 through 6 years. However, the second dose may be administered before age 4, provided at least 28 days have elapsed since the first dose.

• If not previously vaccinated, administer 2 doses with at least 28 days between doses.

7. Varicella vaccine.

• Administer the second dose routinely at age 4 through 6 years. However, the second dose may be administered before age 4, provided at least 3 months have elapsed since the first dose.

• For persons aged 12 months through 12 years, the minimum interval between doses is 3 months. However, if the second dose was administered at least 28 days after the first dose, it can be accepted as valid.

• For persons aged 13 years and older, the minimum interval between doses is 28 days.
