Humoral immune response according to supplementary Se intake. (A) Subjects who reported recent supplementary Se intake did not have significantly different SARS-CoV-2 IgG titres than those who did not supplement Se. (B) Similarly, no differences in neutralising potency (Inhibition in %) was detected between the two groups at any sampling time. Spearman's Rank test was used for correlation analysis, and two-sided Wilcoxon-Rank-sum test was applied to assess differences between groups.
