Rituximab Impairs B Cell Response But Not T Cell Response to <scp>COVID</scp>‐19 Vaccine in Autoimmune Diseases

Abstract

RTX induced a diminished antibody response to the mRNA COVID-19 vaccine, but the functional T cell response was not altered compared to healthy controls and autoimmune disease patients treated with other immunosuppressants. Further work is needed to assess the clinical protection granted by a functionally active T cell response in the absence of an anti-spike antibody response.
