Summary

The purpose of this clinical study is to evaluate the safety and immunogenicity of a 4-dose schedule (3-dose primary series followed by a toddler dose) of V114 compared with Pneumococcal 13-valent Conjugate Vaccine (PCV13). The hypotheses are that: 1) V114 is non-inferior to PCV13 for the 13 shared serotypes between V114 and PCV13 based on the response rates at 30 days following dose 3; 2) V114 is non-inferior to PCV13 for the 2 unique V114 serotypes based on the response rate of the 2 unique V114 serotypes at 30 days following dose 3; 3) V114 is non-inferior to PCV13 for the 13 shared serotypes between V114 and PCV13 based on anti-pneumococcal polysaccharide (PnPs) serotype-specific Immunoglobulin G (IgG) geometric mean concentrations (GMCs) at 30 days following dose 3.
