Background: Patients with cancer often do not receive vaccines to preventable infectious diseases such as influenza and pneumococcal pneumonia because of a lack of knowledge about the optimal timing of vaccination relative to their underlying disease or their current cancer treatments. Cancer immunotherapies, which rely on the ability to promote immune responsiveness to tumors, are a promising therapeutic modality, but their impact on vaccination is largely unexplored.
Methods: We used a pre-clinical mouse model to evaluate the antibody response to a T-dependent (TD) or a Tindependent (TI) antigen immunization with concomitant administration of either checkpoint inhibitors such as antibodies to CTLA-4 or PD-L1 or an antibody to CD40 that has adjuvant properties.
Results: We found that checkpoint blockade with anti-CTLA-4.. View More»
