As of January 26, 2023, EVUSHELDTM is not currently authorized for emergency use because it is unlikely to be active against the majority of SARS-CoV-2 variants circulating in the United States.

What You Need to Know
  • 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.
  • As with vaccines for other diseases, you are protected best when you stay up to date with your COVID-19 vaccines for your age group:
  • COVID-19 vaccine and booster recommendations may be updated as CDC continues to monitor the latest COVID-19 data.

Children and teens aged 6 months–17 years

Adults aged 18 years and older

Staying up to date: If you have completed your primary series—but are not yet eligible for a booster—you are also considered up to date.

To find COVID-19 vaccine locations near you: Search vaccines.gov, text your ZIP code to 438829, or call 1-800-232-0233.

Who Is Moderately or Severely Immunocompromised?

Some people are immunocompromised (have a weakened immune system) due to a medical condition or from receipt of immunosuppressive medications or treatments. Learn more about which medical conditions put you at increased risk of severe COVID-19 illness and death. You can self-attest to your moderately or severely immunocompromised status, which means you do not need any documentation of your status to receive COVID-19 vaccine doses you might be eligible to receive.

Use CDC’s COVID-19 booster tool to learn if and when you can get an updated booster to stay up to date with your COVID-19 vaccines.

People Who Were Vaccinated Outside of the United States

People who are moderately or severely immunocompromised and who received COVID-19 vaccines not available in the United States should either complete or restart the recommended COVID-19 vaccine series, including a booster, in the United States. For more information, talk to your healthcare provider, or see the COVID-19 Interim Clinical Considerations.
