Stay Up to Date with Your COVID-19 Vaccines

The 2023–2024 updated COVID-19 vaccines from Pfizer-BioNTech, Moderna, or Novavax, are recommended to protect against serious illness from COVID-19.

COVID-19 Vaccines

COVID-19 vaccines available in the Unites States are effective at protecting people from severe illness, hospitalization, and death. As with other vaccines, you are protected best from COVID-19 when you stay up to date with the recommended vaccinations. 

The virus continues to evolve and protection against it from previous vaccination decreases over time. 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.

COVID-19 vaccine recommendations may be updated as CDC continues to monitor the latest COVID-19 data.

What You Need to Know

  • CDC recommends the 2023–2024 updated COVID-19 vaccines: Pfizer-BioNTech, Moderna, or Novavax, to protect against serious illness from COVID-19.
  • Children aged 6 months–4 years need multiple doses of COVID-19 vaccines to be up to date, including at least 1 dose of updated COVID-19 vaccine.
  • Everyone aged 5 years and older should get 1 dose of an updated COVID-19 vaccine to protect against serious illness from COVID-19. 
  • People aged 12 years and older who have not previously gotten any COVID-19 vaccine doses and choose to get Novavax should get 2 doses of updated Novavax vaccine to be up to date.
  • People who are moderately or severely immunocompromised may get additional doses of updated COVID-19 vaccine.
  • COVID-19 vaccine recommendations will be updated as needed.

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. Learn more about which medical conditions put you at increased risk of severe COVID-19.

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

2023–2024 Updated COVID-19 Vaccines

As of October 3, 2023, the 2023-2024 updated Novavax vaccine was recommended by CDC for use in the United States.

As of September 12, 2023, the 2023–2024 updated Pfizer-BioNTech and Moderna COVID-19 vaccines were recommended by CDC for use in the United States. Previous versions of these COVID-19 vaccines are no longer available for use in the United States. Read the announcement. 

The 2023–2024 updated COVID-19 vaccines more closely targets the XBB lineage of the Omicron variant and could restore protection against severe COVID-19 that may have decreased over time. We anticipate the updated vaccines will be better at fighting currently circulating variants.

There is no preferential recommendation for the use of any one COVID-19 vaccine over another when more than one licensed or authorized, recommended, and age-appropriate vaccine is available.
