COVID-19 Vaccine Recommendations for Children and Teens

What You Need to Know

  • CDC recommends everyone ages 6 months and older get vaccinated against COVID-19.

  • Everyone 5 years and older should also get a COVID-19 booster, if eligible.

  • Use CDC’s COVID-19 booster tool to learn if and when your child or teen can get boosters to stay up to date with their COVID-19 vaccines.

COVID-19 Vaccine Dosage Is Based on Age on the Day of Vaccination, Not on Size or Weight

Children get a smaller dose of COVID-19 vaccine than teens and adults that is the right amount for their age group.

Children and Teens Who Have Already Had COVID-19 Should Still Get Vaccinated

Emerging evidence indicates that people can get added protection by getting vaccinated after having been infected with the virus that causes COVID-19. Even if a child has had COVID-19, they should still get vaccinated. For children who have been infected with COVID-19, their next dose can be delayed 3 months from when symptoms started or, if they did not have symptoms, when they received a positive test. This possible delay can happen with a primary dose or a booster dose.

COVID-19 Vaccines and Other Vaccines Can Be Given at the Same Visit

Children and teens may get a COVID-19 vaccine and other vaccines, including a flu vaccine, at the same time.
