Booster Doses and Third Doses for Immunocompromised Individuals
For individuals who received Pfizer or Moderna for their first and second dose, the CDC recommends:
For individuals who received a Pfizer-BioNTech or Moderna COVID-19 vaccine, the following groups are eligible for a booster shot at 6 months or more after their initial series:
Johnson and Johnson
For individuals who received a single dose of Johnson and Johnson, the CDC recommends:
- Adults 18 or older who previously received the J&J vaccine at least two months after their first dose
Eligible individuals may choose which vaccine they receive as a booster dose. Some people may have a preference for the vaccine type that they originally received and others, may prefer to get a different booster. CDC’s recommendations now allow for this type of mix and match dosing for booster shots.
Please note that all vaccines types may not be available at all vaccination outreach clinics.
For individuals who are moderately to severely immunocompromised
For individuals who are moderately to severely immunocompromised and who received Pfizer or Moderna for their first and second dose, the CDC recommends:
- People who are moderately to severely immunocompromised are especially vulnerable to COVID-19 because they are more at risk of serious, prolonged illness.
- People who have compromised immune systems may benefit from an additional dose to make sure they have enough protection against COVID-19.
- CDC recommends people who are moderately to severely immunocompromised should receive an additional dose of Pfizer or Moderna after the initial 2 doses.
The CDC recommends third doses to:
- Cancer patients undergoing active treatment for tumors or cancers of the blood;
- Organ transplant recipients who are taking medicine to suppress their immune systems;
- Stem cell transplant recipients who are less than two years out from their transplant and taking medicine to suppress their immune systems;
- Anyone with moderate or severe primary immunodeficiency (such as DiGeorge syndrome, Wiskott-Aldrich syndrome);
- Anyone with advanced or an untreated HIV infection; and
- Anyone receiving high-dose corticosteroids or other drugs that may suppress their immune response.
People should talk to their healthcare provider about their medical condition, and whether getting an additional dose is appropriate for them. Immunocompromised individuals will be asked to self-attest to their status. A note from a medical provider is not required.
A third dose needs to be given at least 28 days after a second dose and should be the same brand as the first and second dose.
