Efficacy and Safety of COVID-19 Vaccine in Cancer Patients

This study gathers information about how a cancer patient responds to COVID-19 vaccine during cancer treatment compared to healthy individuals. The information gained may help determine how effective currently available COVID-19 vaccines are in cancer patients receiving chemotherapy and learn more regarding how long an immune response will last compared to healthy individuals.

PRIMARY OBJECTIVES: I. To determine the antibody response to COVID-19 vaccine after vaccination. II. To assess the adverse events of COVID-19 vaccines in cancer patients. III. To determine the incidence and severity of COVID-19 infection after the vaccination. OUTLINE: Patients undergo blood sample collection at baseline (prior to first COVID-19 vaccination), prior to second vaccination, 1, 6, and 12 months after the last vaccination. Patients receiving a booster vaccine will undergo blood collection prior to and 1-3 months after vaccination. Patients who receive the types of COVID-19 vaccines that do not require the second injection skip blood sample collection at this time point. This study will collect information regarding the type of COVID-19 vaccine received, date of vaccine injection, and any side effects associated with the COVID-19 vaccine that trial participant encountered. This study will also review the medical record for outcomes and information related to the blood testing.
