RSV: babies under 8 months get the antibody in their first RSV season, unless the mother had the RSV vaccine during pregnancy. Flu: children under 9 who get the flu vaccine for the first time need 2 doses, 4 weeks apart. MenB is offered from 16 years after a discussion with your pediatrician (shared clinical decision-making). Children with certain health conditions may need extra vaccines.

AAP and CDC schedules

Since 2025 the US has two childhood schedules that differ in some areas: the AAP schedule and the federal CDC schedule.

Where they differ

For example, the AAP recommends COVID-19 vaccination for all children aged 6 to 23 months and 2 HPV doses from 9 to 12 years. The CDC schedule leaves COVID-19 to a shared decision with your doctor and recommends 1 HPV dose at 11 to 12 years.

Which one this page uses

This page and VaxFile follow the AAP schedule. Ask your pediatrician which schedule their practice follows.

School and childcare

Each state decides which vaccines are required for childcare and school, and which exemptions are allowed. Check your state's health department website.

Not sure what your child has had? Ask your pediatrician. Many states also keep an immunization registry your pediatrician can check.

Questions

Are vaccines required in the US?

There is no national vaccine requirement. Each state requires certain vaccines for childcare and school, and allows exemptions that differ by state.

Are childhood vaccines free in the US?

Most health insurance plans cover routine childhood vaccines. Children who are uninsured or on Medicaid may get free vaccines through the federal Vaccines for Children (VFC) program.

What if my child had vaccines in another country?

Take the records to your pediatrician. They check them against the US schedule, enter them in your child's record and give any missing doses.

Why are there two US schedules?

After changes to federal vaccine recommendations in 2025, the American Academy of Pediatrics published its own schedule. The AAP and CDC schedules now differ for some vaccines, such as COVID-19 and the number of HPV doses.
