IgG antibody levels to Spike and RBD are detected in the Healthy Group (HG), COVID-19 and PP groups. IgG antibodies were determined in sera of HG (n = 304), COVID-19 cases (n = 163) and PP (n = 114). Graphs show IgG levels to A, Spike and B, RBD. The cut-off for positive responses at 0.5 OD 450 nm is indicated by a dotted horizontal line. Data is shown with geometrical mean indicated by horizontal line and 95%CI as error bars. The Kruskal–Wallis test was used to calculate the statistically significant differences (p ≤ 0.05) between groups. C The frequency of individuals who are IgG seropositive to Spike and RBD is shown
