  Purpose
The purpose of this study is to assess the safety, tolerability and immunogenicity of a 13-valent pneumococcal conjugate vaccine (13vPnC), relative to a 7-valent pneumococcal conjugate vaccine (7vPnC) when given concomitantly with routine vaccines in Korea.

Condition Intervention Phase
Pneumococcal Vaccine Biological: 13-valent pneumococcal conjugate vaccine Biological: 7-valent pneumococcal conjugate vaccine Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Care Provider, Investigator)
Primary Purpose: Prevention
Official Title: Phase 2, Randomized, Active-Controlled, Double-Blind Trial Evaluating The Safety, Tolerability, And Immunogenicity Of A 13-Valent Pneumococcal Conjugate Vaccine In Healthy Infants Given With Routine Pediatric Vaccinations In Korea

Primary Outcome Measures:
  • Percentage of Participants Achieving a Serotype-specific Immunoglobulin G (IgG) Antibody Level Greater Than or Equal to (≥) 0.35 Micrograms Per Milliliter (Mcg/mL) Measured 1 Month After the Infant Series [ Time Frame: 1 month after the infant series (7 months of age) ]
    Percentage of participants achieving predefined antibody threshold ≥0.35 Mcg/mL along with the corresponding 95 percent (%) confidence interval (CI) was calculated for 7 common pneumococcal serotypes (serotypes 4, 6B, 9V, 14, 18C, 19F, and 23F) and 6 additional pneumococcal serotypes specific to 13vPnC (serotypes 1, 3, 5, 6A, 7F, and 19A).


Secondary Outcome Measures:
  • Percentage of Participants Achieving a Serotype-specific IgG Antibody Level ≥0.35 Mcg/mL Measured 1 Month After the Toddler Dose [ Time Frame: 1 month after the toddler dose (13 months of age) ]
    Percentage of participants achieving predefined antibody threshold ≥0.35Mcg/mL along with the corresponding 95% CI was calculated for 7 common pneumococcal serotypes (serotypes 4, 6B, 9V, 14, 18C, 19F, and 23F) and 6 additional pneumococcal serotypes specific to 13vPnC (serotypes 1, 3, 5, 6A, 7F, and 19A). Exact 2-sided CI was based on the observed percentage of participants.
