The Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA) recently approved an additional third dose of the COVID-19 vaccine for certain people who are immunocompromised due to a medical condition or because they are receiving medications or treatments that weaken their immune response.
The specific conditions and treatments include but are not limited to:
- 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 in the last 2 years or are taking medicine to suppress the immune system
- Moderate or severe primary immunodeficiency (such as common variable immunodeficiency, DiGeorge syndrome, Wiskott-Aldrich syndrome)
- Active treatment with high-dose corticosteroids or other drugs that may suppress your immune response (for example: azathioprine, cyclophosphamide, cyclosporine, interferon, methotrexate, mycophenolate, biologic medicines/monoclonal antibodies like infliximab, adalimumab, etanercept)
- Advanced or untreated HIV infection
People who are immunocompromised are especially vulnerable to COVID-19 because they are more at risk of serious, prolonged illness, and may benefit from an additional dose to make sure they have enough protection against COVID-19. The CDC recommendation applies to immunocompromised people who received one of the mRNA vaccines (Pfizer or Moderna) and not the one-shot Johnson & Johnson vaccine (J&J).
Cambridge residents who have questions about whether a third dose of vaccine is recommended should contact their medical provider to discuss these recommendations.
