Humoral and Cellular Immune Responses to SARS–CoV‐2 Infection and Vaccination in Autoimmune Disease Patients With B Cell Depletion

Objective B cell depletion is an established therapeutic principle in a wide range of autoimmune diseases. However, B cells are also critical for inducing protective immunity after infection and vaccination. We undertook this study to assess humoral and cellular immune responses after infection with or vaccination against SARS–CoV‐2 in patients with B cell depletion and controls who are B cell–competent. Methods Antibody responses (tested using...
