Coronavirus COVID-19 Vaccine

Moderately or severely immunosuppressed information:

Some people are immunocompromised or have a weakened immune system, because of a medical condition and treatment for the condition. Other people have a weakened immune system because of a life-long condition. Being immunocompromised can make you more likely to get very sick from COVID-19 or be sick for a longer period of time.

People are considered to be moderately or severely immunocompromised due to several types of conditions and treatments, including:

Been receiving active cancer treatment for tumors or cancers of the blood
Received an organ transplant and are taking medicine to suppress the immune system
Received a stem cell transplant within the last 2 years or are taking medicine to suppress the immune system
Moderate or severe primary immunodeficiency (such as DiGeorge syndrome and Wiskott-Aldrich syndrome)
Advanced or untreated HIV infection
Active treatment with high-dose corticosteroids or other drugs that may suppress your immune response.

For people who are immunocompromised, the third primary dose is the final dose of the primary series of an mRNA COVID-19 vaccine.

If you are moderately or severely immunocompromised or severely allergic to COVID-19 vaccines, you may be eligible for Evusheld, a medicine given by your healthcare provider to help prevent you from getting COVID-19. Talk to your healthcare provider to find out if this option is right for you.

Booster Dose Information:

Boosters are shots that enhance or restore protection against COVID-19, which may have decreased over time. You are up to date with your COVID-19 vaccines when you have received all doses in the primary series and all boosters recommended for you, when eligible.

People ages 18 years and older may get a different product for a booster than they got for their primary series. Children and teens ages 5 through 17 years who got a Pfizer-BioNTech primary series must get Pfizer-BioNTech for a booster.

People ages 18 through 49 years who received a J&J/Janssen COVID-19 vaccine for both their primary dose and booster can choose to get a 2nd booster of either Pfizer-BioNTech or Moderna COVID-19 vaccine at least 4 months after their 1st booster. J&J/Janssen COVID-19 vaccine cannot be used as a 2nd booster dose. The 2nd booster is not required to be considered up to date for people ages 18 through 49 years who got a J&J/Janssen COVID-19 vaccine for both their primary dose and 1st booster.

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