In the context of malignant disease, it is likely that vaccine efficacy and immunogenicity depends on the type of pathology, stage of the disease, immunosuppression induced by the treatments, in addition to more classic factors such as age, general condition and possibly the type of vaccine used. There are very little data on the efficacy and immunogenicity of anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines in patients with malignant disease in the active phase of treatment. This multicenter observational study aims to assess the efficacy and the immunogenicity of anti-Sars-CoV-2 vaccines in the cohort of patients treated for malignant pathology (solid or hematological tumors) at Saint Louis Hospital and in thoracic oncology patients at Bichat Hospital.
