You may be able to get a third dose of the Pfizer or Moderna vaccine if any of these descriptions are true for you:

  • You currently receive cancer treatment for tumors or cancers of the blood
  • You received an organ transplant and take medicine to suppress your immune system
  • You received a stem cell transplant within the past 2 years or are taking post-transplant medicine to suppress your immune system
  • A health care provider has diagnosed you with a moderate-to-severe primary immunodeficiency (like DiGeorge or Wiskott-Aldrich syndrome) 
  • You have advanced or untreated HIV infection
  • You currently take high-dose corticosteroids or other medicines that may suppress your immune system
