SARS-CoV-2 IgG antibody levels (logarithmic titres, BAU/mL) by type of COVID-19 vaccination among those vaccinated three times (N = 1138) Boxplots showing medians, interquartile ranges and 95% confidence intervals of logarithmic IgG antibody titres by time since last COVID-19 vaccine dose and type of COVID-19 vaccination. 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. Abbreviations: IgG: Immunoglobulin G, N: Number of Participants, Vaccination schemes: AZ/AZ/BT = 2 doses ChAdOx1-S + BNT162b2 booster (N = 155), AZ/BT/BT = 1 dose ChAdOx1-S, 1 dose BNT162b2 + BNT162b2 booster (N = 369), BT/BT/BT 3 W = 2 doses BNT162b2 (3 weeks apart) + BNT162b2 booster (N = 430), BT/BT/BT 6 W = 2 doses BNT162b2 (3 weeks apart) + BNT162b2 booster (N = 128), MOD = Vaccine combinations with at least one dose mRNA-1271 (N = 56)
