TASMANIA is a single-center prospective observational study with 1000 kidney transplant recipients from Institute for Clinical and Experimental Medicine (IKEM), Prague. The primary objective of the study is to assess humoral immune response to SARS-CoV-2 mRNA vaccines in SARS-CoV-2-naive kidney transplant recipients using immunochemiluminescent assay. As comparator several cohorts will be evaluated: kidney transplant recipients with previous SARS-CoV-2 exposition verified by real-time reverse transcription polymerase chain reaction (RT-PCR) kidney transplant recipients vaccinated on waiting list (a) SARS-CoV-2 naive (b) SARS-CoV-2 previously exposed The secondary objective is to determine clinical variables affecting antibody levels. SARS-CoV-2 anti S1/2 antibodies will be tested ? 15 days after the second dose of mRNA vaccines and in 3 months after the first blood sampling. In subanalysis 50 kidney transplant recipients will be examined for a cell-mediated immune response after SARS-CoV-2 mRNA vaccine Enzyme Linked using Immuno Spot (ELISPOT) assay.
