Follows the CDC/ACIP schedule. A few doses (Hib 3rd/4th, rotavirus 3rd, COVID-19) depend on the vaccine brand used or current CDC guidance - your pediatrician confirms the exact plan.
This is a reference, not medical advice. Ages are the recommended targets; your clinic sets the exact appointments and will advise on your individual child. If your child has a medical condition, was premature, or is behind schedule, speak to your GP, health visitor or paediatrician.

How to book in United States

Vaccinations are given by your child's pediatrician or family doctor, at many pharmacies, and at public health clinics. The Vaccines for Children (VFC) program covers the cost for eligible children. Ask your provider to review your child's record at every well-child visit.

The full schedule by age

Tap any milestone to expand it. Each vaccine explains what it is, the diseases it prevents, and why it is given at that age.

BirthNewborn1 vaccine

Hepatitis B (HepB)1st of 3

Hib (meningitis, epiglottitis, pneumonia)

Before this vaccine Hib was the leading cause of bacterial meningitis in young US children. It is now rare.

    About the United States schedule

    In the United States the childhood immunization schedule is published each year by the Centers for Disease Control and Prevention (CDC) on the recommendation of the Advisory Committee on Immunization Practices (ACIP), and it is endorsed by the American Academy of Pediatrics.

    Vaccines begin at birth with the first hepatitis B dose and continue at well-child visits at 2, 4, 6, 12 and 15-18 months, then again at ages 4-6 and 11-12. Most children are fully caught up by their pre-kindergarten visit.

    The Vaccines for Children (VFC) program provides these vaccines at no cost for eligible children. This page explains every vaccine on the CDC schedule and when your child is due - enter a date of birth for a personal timeline.

    How the US compares

    The US's routine schedule protects against 17 diseases across 10 vaccination ages, 5 of them in the first year. By age 2 a child has had about 24 vaccine doses, including oral drops against rotavirus.

    Less common elsewhere: The US routinely vaccinates against Flu and Hepatitis A, which fewer than half of the other 13 countries on this site include for every child.

    Compare the US with any other country, disease by disease.

    Behind schedule or new to the US? Almost every dose still counts, and your clinic can plan a catch-up - see common questions or moving to the US.
