From: Humoral immune response after different SARS-CoV-2 vaccination regimens
Anti-SARS-CoV-2 immunoglobulin G (IgG) response in Binding Antibody Units (BAU) per millilitre (ml) after first (empty circles) and second (filled circles) immunisation with the vector vaccine AZD1222 or the messenger ribonucleic acid (mRNA)-based vaccines BNT162b2 or mRNA-1273. The cut-offs for positivity (i.e. presence of anti-SARS-CoV-2 IgG including borderline results) of anti-trimeric spike (S) IgG assay (A), of the anti-S IgG assay (B) and of the anti-receptor binding domain (RBD) IgG assay (C), respectively, are marked by dashed lines. The median and the 95% confidence interval were calculated for each group. Ns non-significant; *p < 0.05; **p < 0.01; ****p < 0.0001 (Kruskal-Wallis test)
