The responses of total antibody and IgG antibody against SARS-CoV-2 among college students. (A, D) Total antibody and IgG antibody responses during the uninfected, breakthrough infection and reinfection among the 876 fully vaccinated college students. (B, E) Total antibody and IgG antibody responses against SARS-CoV-2 who experienced breakthrough infections and/or reinfections after the BA.5/BF.7 wave and/or the XBB.1.5 wave. (C, F) Total antibody and IgG antibody responses for uninfected, breakthrough infection < 6 months, 6–9 months, > 9 months, and reinfection < 6 months, 6–9 months according to the time of infection. All values are presented as the median and interquartile range. The black dotted line represents the positivity cutoff for neutralizing antibodies (total antibody: <10 AU/ml is negative; IgG: S/CO < 1.0 COI is negative). IgG, immunoglobulin G.
