Kinetics of humoral immune responses approximately 3 months after the 2nd vaccine dose in cirrhotic PWLD and non-cirrhotic PWLD. (a) Anti-SARS-CoV-2 S1-protein IgG antibody titers; (b) neutralizing activity. PWLD—patients with liver disease; SARS-CoV-2—severe acute respiratory syndrome coronavirus 2; OD450—optical density of serum samples measured at 450 nm; ODcal—optical density of calibrator; ns—non-significant; * p < 0.05; ** p < 0.01; *** p < 0.001
