Everyone Ages 5 Years and Older

Get one dose of updated Pfizer-BioNTech or Moderna COVID-19 vaccines, regardless of whether you received any original COVID-19 vaccines. You are eligible to receive an updated dose at least two months after your last dose of any COVID-19 vaccine.

Children Ages 6 Months – 4 Years

Depending on the number of doses and brand of vaccine they’ve previously received and their age, some children may need multiple doses of COVID-19 vaccine to be up to date, including at least one dose of updated Pfizer-BioNTech or Moderna COVID-19 vaccine.

Pfizer-BioNTech

Age 6 months – 4 years: Three (3) doses updated Pfizer-BioNTech vaccine, second dose 3-8 weeks after first dose and third dose 8 weeks after second doses

Moderna

Age 6 months – 5 years: Two (2) doses updated Moderna vaccine, 4-8 weeks apart

Children Who Have Previously Been Vaccinated

Children ages 6 months–4 years who got COVID-19 vaccines before Sept. 12, 2023, should get one or two doses of updated COVID-19 vaccine depending on which vaccine and the number of doses they previously received. Learn more

If You Are Moderately or Severely Immunocompromised

People who are moderately or severely immunocompromised need additional doses of COVID-19 vaccine. People with a weakened immune system may be at greater risk for severe COVID-19 illness and their immune response to the vaccine may not be as strong as in other people. Visit this page to find out exactly what you need.

What Does it Mean to be Immunocompromised?

Individuals who meet the following criteria may benefit from additional doses of the vaccines:

• Age 6 months and older
• Currently receiving active cancer treatment for tumors or blood cancers
• Received an organ transplant and are taking medicine to suppress the immune system
• Received a stem cell transplant within the last two years or are taking medicine to suppress the immune system
• Have moderate to severe primary immunodeficiency such as DiGeorge syndrome or Wiskott-Aldrich syndrome
• Advanced or untreated HIV infection
• Active treatment with high-dose corticosteroids or other drugs that may suppress the immune response

Please speak with your provider about your health conditions and to determine if an additional dose is appropriate for you.

Visit the CDC website to learn more about which vaccines and how many doses you need.

If You Have Had COVID-19

If you have recently had COVID-19, you may consider delaying receiving your vaccine by three months from when your symptoms started or after receiving a positive test result if you had no symptoms.
