Study design and dynamics of immunity to SARS-CoV-2 from baseline to 6 months post-vaccination. a Study design. b sVNT levels from baseline to 6 months after the second vaccine dose (post vaccination, p.v.). P values were given by paired Wilcoxon’s rank-sum tests and were FDR-corrected. c Relative drop in sVNT level from 1 month to 6 months p.v. d sVNT levels at 6 months after the second vaccine dose by vaccination history. P value was given by Wilcoxon’s rank-sum test. Elements on boxplots: centre line, median; box limits, upper and lower quartiles; whiskers, 1.5 × IQR; points, outliers
