Immunogenicity and safety of 13-valent and 7-valent pneumococcal conjugate vaccines (PCV13; PCV7) were compared in Taiwanese children.In this double-blind, multicenter study, healthy children were randomly assigned to receive PCV13 (n= 84) or PCV7 (n= 84) at 2, 4, 6 and 15 months with routine pediatric vaccines.For the 7 PCV13/PCV7 common serotypes, serotype-specific immunoglobulin G (IgG) geometric mean concentrations (GMCs) were high 1 month postinfant series, with ≥95.0% in both groups achieving IgG levels ≥0.35 μg/mL, with a trend to lower IgG GMCs for PCV13 compared with PCV7 (PCV13:PCV7 GMC ratios 0.59-0.91). For the 6 additional serotypes unique to PCV13, GMCs were notably higher after PCV13 than PCV7 (PCV13:PCV7 GMC ratios 1.50-202.58). Immune responses generally increased posttoddler dose. Safety was similar between groups.PCV13 was safe and immunogenic in this Taiwanese population. PCV13 should offer broader protection than PCV7 against pneumococcal disease.Clinical trials registration number: NCT00688870.
