SARS-CoV-2 IgG antibody levels (logarithmic titres, BAU/ml) by COVID-19 vaccination status and evidence of previous laboratory-confirmed SARS-CoV-2 infection (N = 1495) Boxplots showing medians, interquartile ranges and 95% confidence intervals of logarithmic IgG antibody titres by COVID-19 vaccinations status and evidence of SARS-CoV-2 infection. P-values are only shown for statistically significant differences (i.e., p-value < 0.05) between groups estimated by Kruskal-Wallis ANOVA using Dunn’s test for pairwise multiple comparisons
