Fig. 2. Post-third vaccination anti-spike IgG antibody levels according to the rate of symptomatic breakthrough infections or hospitalization. The P-values for all pairwise comparisons by pairwise Wilcoxon tests are as follows: no infection vs. infection without hospitalization, P=0.040; infection without hospitalization vs. infection with hospitalization, P=0.016; no infection vs. infection with hospitalization, P=0.0001. *P<0.05, **P<0.005, ***P<0.001.
Abbreviation: RBD, receptor-binding domain.
