Here in the United States, the Food and Drug Administration has granted emergency use authorization for a third shot of the Pfizer or Moderna vaccine to certain immunocompromised people. Centers for Disease Control and Prevention Director Rochelle Walensky said Thursday the shots will be made available to cancer patients, organ transplant recipients and others who are less able to mount an effective immune response to vaccines.
Dr. Rochelle Walensky: “To be clear, this is a very small population. We estimate it to be less than 3% of adults.”
