Proportions of women with serotype-specific IgG concentrations ≥2.5 or ≥ 5.0 μg/mL pre- and post-PCV13 vaccination. Serotype-specific IgG concentrations were measured before and 1 month after PCV13 vaccination. Thresholds of ≥2.5 μg/mL and ≥ 5.0 μg/mL were studied as indicators of antibody concentrations high enough to confer protection in newborns for the first 3 months and 6 months of life, respectively. Significant increases in the proportion of women with antibody titers above the specified threshold before and after vaccination are indicated with an asterisk (*, p < 0.05 based on McNemar test)
