a–d, Graphs show the ability of plasma samples from seronegative and seropositive vaccinees to bind the S protein trimer, RBD, NTD and S2 domain. Mean and standard deviation are denoted on each graph. Technical triplicates were performed for each experiment. e, The graph shows the neutralizing activity of plasma samples against the original Wuhan SARS-CoV-2 virus. Technical duplicates were performed for each experiment. f, The table summarizes the 100% inhibitory dilution (ID100) of each COVID-19 vaccinee and the geometric mean for seronegative and seropositive donors.
