Data are presented as median (interquartile range [IQR]) unless otherwise indicated. Table shows the median fold-increase at 4 and 7 weeks postvaccination from baseline and IQR per serotype per vaccinated group (PCV13, n = 9 and HepA, n = 10). For comparison of immunoglobulin G levels between baseline and 4 or 7 weeks, adjusted P values are shown as calculated after correction for multiple comparisons using Dunn test.

Abbreviations: BL, baseline; HepA, hepatitis A vaccine; PCV13, 13-valent pneumococcal conjugate vaccine.
