Considerations for Coronavirus Disease 2019 Vaccination Among B-Cell-Depleted Patients

This article provides a comprehensive review of the impact of B-cell-directed therapy on severe acute respiratory syndrome coronavirus 2 vaccine immunity, focusing on its implications in autoimmune inflammatory rheumatic diseases (AIIRD). Rituximab (RTX) is the primary B-cell-depleting drug that has been studied in AIIRD and is the focus of this review. We review the pivotal role of B cells in vaccine response and propose strategies to manage and predict vaccine responses in B-cell-depleted individuals. We highlight the need to strategize patients into distinct groups when predicting vaccine responses and developing guidelines to ensure optimal outcomes for RTX-treated patients.
