Article Snippet: NAb was measured using the GenScript SARS-CoV-2 cPASS surrogate virus neutralization test (sVNT) kit (Genscript Biotech Corporation, Piscataway, NJ, USA) and spike-specific immunoglobulin G (IgG) was measured with the Euroimmun anti-SARS-CoV-2 IgG enzyme-linked immunosorbent assay (ELISA) (Euroimmun, Lübeck, Germany).

Figure Lengend Snippet: Locally estimated scatterplot smoothing curve based on data from the first blood sample collection, illustrating the relationship of antibody levels as follows: ( A – C ) inhibition rates (%) for the surrogate virus neutralization test (sVNT) against the wild-type (WT) strain, ( D – F ) inhibition rates (%) against the Omicron variant, and ( G – I ) IgG levels. The curves are plotted against the number of days since COVID-19 infection ( A , D , G ), the last vaccination ( B , E , H ), and the last exposure to COVID-19 ( C , F , I ). The blue line represents the regression line, and the shaded gray area indicates the 95% confidence interval.

Figure Lengend Snippet: Levels of anti-spike antibodies in sera of participants as determined using an in-house ELISA. Arbitrary units were calculated against the WHO international standard anti-SARS-CoV-2 immunoglobulin. The dash line representing the cutoff was calculated from the mean arbitrary units of the control group plus 2 standard deviations (54.28). Each symbol represents one individual. The vertical lines and error bars indicate the median and interquartile range. The p values were calculated from the post hoc comparisons using the Kruskal–Wallis Test.
