SARS-CoV-2 S IgG antibody values in serum samples of actively treated patients with cancer (n=72) and healthy controls (n=144) before (blue circles dots) and after (red squares) the third dose of BNT162b2 vaccine Boxes represent median SARS-Cov-2 S IgG antibody concentrations and whiskers represent upper and lower quartiles. Each dot represents one participant. The y-axis (log10 scale) represents SARS-Cov-2 S IgG antibody WHO BAU/ML values transformed to log10 scale. Dashed line represents cutoff level for seropositivity. Significant differences were assessed by related-samples sign test for the comparison within a group and independent-samples Mann-Whitney U and Kolmogorov-Smirnov tests. After a third dose patients with cancer have lower plasma concentrations of SARS-Cov-2 S IgG antibodies compared with healthy individuals (p=0·00011).
