SARS-CoV-2–specific T-cell response in all participants at 1 of the participating centers. A, Percentage of T-cell responders per group 6 months after vaccination (defined as Antigen-2 ≥0.15 IU/mL). B, Individual IFN-γ levels per group, with the horizontal line representing the median value. Dotted horizontal line indicates the threshold of detectable T-cell response (≥0.15 IU/mL). P values were calculated using the Wilcoxon signed rank test. Abbreviations: CKD G4/5, chronic kidney disease stages 4/5; IFN-γ, interferon gamma; KTR, kidney transplant recipient.
