Safety and Immunogenicity of Catch-up Vaccination Regimens of V114 (V114-024)

Summary

The purpose of this study is 1) to evaluate the safety and tolerability of V114 with respect to the proportion of participants with adverse events (AEs) and 2) to evaluate the anti-pneumococcal polysaccharide (PnPs) serotype-specific Immunoglobulin G (IgG) Geometric Mean Concentrations (GMCs) at 30 days following the last dose for each vaccination group. There is no formal hypothesis testing in this study.
