Humoral immune response (IgG, IgM, IgA) profiles of SARS-CoV-2 infections: onset and persistence of neutralising antibodies. a Onset within 10–14 days [27,28,29,30,31,32]; levels remain elevated for weeks [30, 33,34,35,36,37,38]; peaks at around day 25 [26]. b Rises within the first week of infection [30, 31, 33, 39]; lasts 1-2 months before gradually diminishing [15, 30, 38]; peaks at around 20–30 days post-symptom onset [40]. c Onset within 6–8 days [39]; lasts 71 days [38]; peaks at around 20–22 days post-symptom onset [39, 40]; high titres in severe COVID-19 cases [32]
