ED50 of SARS-CoV-2 spike- (A) and RBD-specific (B) IgG antibodies in the NHPs sera 15 days after administration of the first dose (day 15), 7 days after the second dose of vaccination (day 37) and 21 days after the second dose (day 51). Average of duplicate values for each sample is shown. Statistical comparison of ED50 values were performed using Kruskal–Wallis test for each timepoint. p-values were adjusted for multiple testing using Dunn’s multiple comparison test. ns: no significance, * p ≤ 0.05, ** p ≤ 0.01, *** p ≤ 0.001, **** p ≤ 0.0001.
