Spike- (a), Receptor-Binding Domain- (b) and Nucleoprotein- (c) specific IgG antibodies measured in sera of rhesus and cynomolgus macaques. Sera were collected from uninfected animals (day 0) or 1–3, 4–6, 8–9, 11–12 and 14–19 days following SARS-CoV-2 infection. n = 6 at 0, 1–3 and 4–6 dpc; n = 4 at 8–9, 11–12 and 14 dpc. Bars show the group mean±SEM with an endpoint titre determined for each individual animal shown as squares for males and dots for females. *p ≤ 0.05 (Kruskal–Wallis one-way ANOVA, two-sided). Experiment performed in duplicates.
