The main points of the pathogenesis of the influence of monoclonal anti-CD20 antibodies on the course of COVID-19 are described. The current trends in the modification of the accepted algorithms of lymphoproliferative diseases therapy with the inclusion of monoclonal anti-CD20 antibodies are summarized, and the possibilities of specific prevention by vaccination against COVID-19 are also considered.</p></abstract><trans-abstract xml:lang="ru"><p>В настоящем обзоре представлены результаты сочетанного анализа данных литературы и собственных клинических наблюдений относительно безопасности и целесообразности применения моноклональных анти-CD20-антител в терапии B-клеточных лимфопролиферативных заболеваний в условиях пандемии новой коронавирусной инфекции COVID-19.
