Box-and-whisker plot of surrogate virus neutralization test (sVNT). (A) Titer of anti-receptor-binding domain (RBD) IgG antibodies from serially diluted mice vaccinated sera taken 2 weeks after the third immunization. (B) Titer of anti-RBD IgG antibodies from serially diluted mice vaccinated sera taken 2 weeks after the fourth immunization. Cutoff titer was calculated as the serum highest dilution showing a cutoff value >20%. Data were analyzed with one-way ANOVA with Tukey’s multiple comparison test. The asterisks refer to the level of significance: * p < 0.033; ns: no significant difference.
