What You Need to Know
CDC recommends everyone stay up to date with COVID-19 vaccination, including all primary series doses and boosters for their age group:
Ages 6 months through 4 years should get all COVID-19 primary series doses,
Ages 5 years and older should get all primary series doses, and updated COVID-19 boosters if eligible.
Getting a COVID-19 vaccine after you recover from COVID-19 infection provides added protection against COVID-19.
People who are moderately or severely immunocompromised have different recommendations for COVID-19 vaccines, including boosters.
For people ages 12 years and older, the only authorized mRNA booster is the updated (bivalent) booster. People ages 12 years and older can no longer get the original (monovalent) mRNA booster.
COVID-19 vaccine and booster recommendations may be updated as CDC continues to monitor the latest data.
About COVID-19 Vaccines
COVID-19 vaccines available in the United States are effective at protecting people from getting seriously ill, being hospitalized, and dying. As with other diseases, you are protected best from COVID-19 when you stay up to date with the recommended vaccines, including recommended boosters.
Four COVID-19 vaccines are approved or authorized in the United States to prevent COVID-19: Pfizer-BioNTech, Moderna, Novavax, and Johnson & Johnson’s Janssen (J&J/Janssen). It’s recommended that the J&J/Janssen COVID-19 vaccine only be considered in some situations.
Updated COVID-19 boosters can both help restore protection that has decreased since previous vaccination, and provide broader protection against newer variants. The updated, or bivalent boosters, target the most recent Omicron subvariants, BA.4 and BA.5, that are more contagious and more resistant than earlier strains of Omicron.
When Are You Up to Date?
You are up to date with your COVID-19 vaccines if you have completed a COVID-19 vaccine primary series and received the most recent booster dose recommended for you by CDC.
Vaccine recommendations are based on your age, the vaccine you first received, and time since last dose. People who are moderately or severely immunocompromised have different recommendations for COVID-19 vaccines.
Find Out When You Can Get Your Booster
Boosters are an important part of protecting yourself from getting seriously ill or dying from COVID-19. They are recommended for most people. Use this tool to determine when or if you (or your child) can get one or more COVID-19 boosters. Find Out When to Get a Booster
This tool is intended to help you make decisions about getting COVID-19 vaccinations. It should not be used to diagnose or treat COVID-19.
Children and teens ages 6 months–17 years
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 based on the age group they belong to.
