Abstract

We reviewed 24 kidney transplantat recipients (KTRs) who had radiologically confirmed coronavirus disease 2019 (COVID-19) pneumonia. Enrolled KTRs were divided into a severe acute respiratory syndrome coronavirus 2 (SARSCoV-2)-vaccination (+) group (n = 18) and a vaccination (-) group (n = 6). Clinical outcomes of the two groups including death, pulmonary outcome, and renal outcome were compared. COVID-19 pneumonia was worse in vaccination (-) KTRs. Two out of six vaccination (-) KTRs needed continuous renal replacement therapy (CRRT) and mechanical ventilator (MV) and expired. In contrast, only one KTR expired and required CRRT and MV out of 18 vaccination (+) KTRs. Our results suggest that SARS-CoV-2 vaccination attenuates severity of COVID-19 pneumonia in KTRs.
