Responses to COVID19 Vaccination in Patients With a Treatment History of Rituximab. (RituxiVac)
27. mai 2021 oppdatert av: University Hospital Inselspital, Berne
Registry Study for COVID19 Vaccination Efficacy in Patients With a Treatment History of Rituximab.
Patients with treatment history of rituximab since 01.01.2019 and immunocompetent volunteers will be contacted to give a blood sample after their COVID19 vaccination, and in a subset also before vaccination.
Immune responses of antibodies and SARS-CoV2-specific T-cells to the vaccination will be quantified and the rituximab effect on COVID19 vaccine-induced immune responses is analyzed.
