COVID-19 Vaccine Recommendations

COVID-19 vaccines available in the United States are effective at protecting people from getting seriously ill, being hospitalized, and dying.

Getting a COVID-19 vaccine is a safer, more reliable way to build protection than getting sick with COVID-19. COVID-19 vaccines can also offer added protection to people who had COVID-19, including protection against being hospitalized from a new infection.

As with other vaccines, you are protected best from COVID-19 when you stay up to date with the recommended vaccinations, including recommended boosters, when you are eligible.

When Are You Up to Date?

You are up to date with your COVID-19 vaccines when you have completed a COVID-19 vaccine primary series and got the most recent booster dose recommended for you by CDC.

COVID-19 vaccine recommendations are based on three things:

  1. Your age
  2. The vaccine you first received, and
  3. The length of time since your last dose

Learn more about when you should get a COVID-19 vaccine from the CDC or use the tool below to see when you can get a booster dose.

Updated COVID-19 Vaccines

Updated, or bivalent, COVID-19 boosters can help restore protection that has decreased since your previous vaccination and provide broader protection against newer variants. The updated boosters target both the original virus and more recent Omicron subvariants, BA.4 and BA.5, that are more contagious and more resistant than earlier strains of the virus.

CDC recommends one updated booster dose:

  • For everyone aged 5 years and older if it has been at least 2 months since your last dose.
  • For children aged 6 months4 years who completed the Moderna primary series and if it has been at least 2 months since their last dose. 

The updated Pfizer-BioNTech COVID-19 vaccine also became available on December 9, 2022 for children aged 6 months–4 years to complete the primary series. However, there is no booster recommendation for children aged 6 months–4 years who completed the Pfizer-BioNTech COVID-19 vaccine primary series.

Guidance for People Who are Immunocompromised

If you are moderately or severely immunocompromised (have a weakened immune system), you are at increased risk of severe COVID-19 illness and death. Additionally, your immune response to COVID-19 vaccination may not be as strong as in people who are not immunocompromised. 

People who are moderately or severely immunocompromised have different recommendations for COVID-19 vaccines.
