ALEXANDRIA, Va. – In a study of more than 1,100 people with COVID-19 undergoing treatment for cancer, researchers found lower COVID-19 vaccination rates among patients with comorbidities, metastatic solid tumors or non-B-cell hematologic malignancies, and those living in areas with lower education attainment and higher levels of unemployment. The study, funded by Conquer Cancer®, the ASCO Foundation, was published today in Cancer.
