Dynamics of humoral immune responses in patients on hemodialysis after standard vaccination with two injections of 30 µg of BNT162b2. (a) Binding serum antibody titers determined after 0, 6, 12, and 24 weeks after the first vaccination. (b) Neutralizing antibody titers assessed after 6 and 24 weeks after the first vaccination. Circles represent the antibody titers of each subject; black bars represent median antibody titers with their corresponding interquartile ranges. Statistical analysis: Kruskal–Wallis Test followed by Dunn’s multiple comparison test; * = p < 0.05, *** = p < 0.001; ns = non-significant.
