While most individuals had broad isotype and subclass responses to each antigen shortly after infection, only RBD and S protein IgG, as well as NAbs, were relatively stable over the study period, with 99%, 96% and 90% of samples, respectively, having responses over baseline 4-8months post-infection. Anti-RBD antibodies were strongly correlated with NAbs at all time points (Pearson's ≥0.87), and feasibility of using finger prick sampling to accurately measure anti-RBD IgG was demonstrated. Antibodies to SARS-CoV-2 persist for
