HIV and cancer patients, organ transplant recipients and those taking immunosuppressant drugs comprise about 2.7% of the U.S. adult population, and growing evidence has indicated the population doesn’t respond as well to COVID-19 vaccines, inducing lower levels of protective antibodies.

"As an organization dedicated to improving the lives of cancer patients and their families, the American Cancer Society strongly supports efforts to protect and improve the health and well-being of our community," Dr. Karen E. Knudsen, CEO of the American Cancer Society and American Cancer Society Cancer Action Network, told Fox News.

ACS urged all those eligible for COVID-19 vaccinations to roll their sleeves and receive a vaccine, including cancer patients in consultation with a health care provider.

It is not immediately clear which immunocompromised patients will become eligible for a third dose, however reports have noted solid organ transplant recipients and patients with similar compromised immune systems could fall under the expanded authorization.
