Figure 1. Immune Response in Participants with or without Previous SARS-CoV-2 Infection.
Shown are titers of circulating severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) anti-spike IgG antibodies (Panel A) and neutralizing SARS-CoV-2 anti-spike IgG antibodies (Panel B) in serum samples obtained from previously infected participants after they received a single dose of vaccine and in samples obtained from previously uninfected participants after they received a second dose of vaccine. Differences in circulating (Panel C) and neutralizing (Panel D) IgG antibodies in samples obtained from previously infected participants were evaluated according to the duration from natural infection to vaccination (1 to 2 months, >2 months to 3 months, or >3 months). In each box-and-whisker plot, the horizontal line represents the median, the top and bottom of the box the interquartile range, and the whiskers the minimum and maximum values. GMT denotes geometric mean titer.
