Study Shows Cancer Patients Can Safely Receive COVID-19 Vaccines
A study yesterday in the Journal of Clinical Oncology shows COVID-19 vaccines are safe in people undergoing treatment for cancer and produce modestly impaired immune responses. Booster vaccine doses, however, enhance immunity. The study was based on 762 active oncology patients at Massachusetts General Hospital, who were compared to 1,638 healthy controls. The patients were currently receiving cancer treatments, including chemotherapy, bone marrow transplants, corticosteroids, and radiation. All three vaccines currently used in the United States were included in the study. (11/11)
