Boosters


The Centers for Disease Control and Prevention recommends everyone age 5 and older, including people who are immunocompromised and therefore received a third dose of Pfizer or Moderna, get a booster dose. People 12 and up who are immunocompromised, 50 years of age and older or received both a primary and booster dose of Johnson & Johnson should receive a second booster dose of an mRNA vaccine four months after their first booster dose. Proof of eligibility is not required, though providers may ask for confirmation of your last dose. People can get a booster dose at most locations that provide COVID-19 vaccines.


Is a booster recommended for the vaccine you received?

Pfizer and Moderna

The CDC recommends people age 5 and older get a booster dose five months after their second dose of a Moderna or Pfizer vaccine. People who are age 50 and older should receive a second booster dose of either Pfizer or Moderna four months after their first booster dose. People 5–17 years old are only eligible to receive the Pfizer vaccine.

Johnson & Johnson

The CDC recommends everyone 18 and older get a booster dose two months after a Johnson & Johnson (Janssen) dose. People who received both a primary and booster dose of Johnson & Johnson are eligible to receive a second booster dose of an mRNA vaccine four months after their first booster dose.

The CDC recommends people age 5 and older get a booster dose when they are eligible: five months after their second dose of a Moderna or Pfizer vaccine and two months after a Johnson & Johnson (Janssen) vaccine dose. People 5 and older who are immunocompromised and received a third dose of Pfizer or Moderna are recommended to receive a booster dose three months after their third dose. People who are 50 years of age and older, immunocompromised persons at least 12 years old, and persons who received both a primary and booster dose of Johnson & Johnson should receive a second booster dose of an mRNA vaccine four months after their first booster dose. People 5–17 years old are eligible to receive only the Pfizer vaccine.

Booster doses are widely available through pharmacies, doctor's offices and clinics, as COVID-19 vaccine is today. Please do not go to a hospital to get a booster shot. Contact your community health center or doctor's office to get your booster there. Or use our vaccine locator to find a vaccine provider near you. You may need to make an appointment. But don't worry – your current vaccination still offers strong protection against serious COVID-19 illness.

For older adults and others who live in skilled nursing facilities, their residences are equipped to provide booster doses once they are fully authorized.

Boosters and additional doses for immunocompromised people


An additional dose is recommended for people ages 5 and up who are immunocompromised and received Moderna, Pfizer or Johnson & Johnson.

People 5–17 years old are eligible to receive only the Pfizer vaccine. Booster doses are recommended for all people 5 and older.


Is an additional dose recommended for the vaccine you received?

Pfizer and Moderna

 A third dose of Pfizer or Moderna is recommended for immunocompromised people at least 28 days after the second dose. People 5-17 years old are only eligible to receive the Pfizer vaccine.

A booster dose is recommended for immunocompromised people 5 and older three months or more after their third dose. Immunocompromised people 12 and older should receive a second booster dose four months after their first booster dose.

Johnson & Johnson

For people ages 18 and older who are immunocompromised and who received Johnson & Johnson (Janssen) vaccine, a second dose of an mRNA COVID-19 vaccine (Moderna or Pfizer) is recommended at least 28 days after the first dose.

Everyone who received a Johnson & Johnson (Janssen) vaccine is advised to get a booster dose. An mRNA vaccine is recommended.

People who are immunocompromised and already received a booster dose (Moderna, Pfizer or Johnson & Johnson) after receiving a single dose of the Johnson & Johnson vaccine are recommended to get an additional dose of an mRNA vaccine two months after their booster dose.

People who are immunocompromised may receive a second booster dose of an mRNA vaccine four months after their first booster dose or four months after their additional dose (if the additional dose was received after the booster dose.)

The Centers for Disease Control and Prevention (CDC) recommends that people with moderately to severely compromised immune systems receive an additional dose of mRNA COVID-19 vaccine at least 28 days after a second dose of Pfizer-BioNTech COVID-19 vaccine or Moderna COVID-19 vaccine.

This includes people who have:

  • 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, Wiskott-Aldrich syndrome)
  • Advanced or untreated HIV infection
  • Active treatment with high-dose corticosteroids or other drugs that may suppress your immune response

People should talk to their health care provider about their medical condition, and whether getting an additional dose is appropriate for them.
