a Longitudinal analysis of Ab binding to Wuhan S and VOC Alpha, Beta, Gamma, and Delta in macaques. Datapoints represent mean relative MFIs, error bars indicate SD. b Paired comparisons of Ab binding to Wuhan S and Beta S two weeks after the second and third vaccination, and to Wuhan S two weeks after the second vaccination and Beta S two weeks after the third vaccination. The relative MFIs between variants were compared using the Wilcoxon test (*P < 0.05).
