A Phase 3, Randomized, Double-Blind Study to Evaluate the Safety, Tolerability, and Immunogenicity of V116 in Children and Adolescents With Increased Risk of Pneumococcal Disease

Merck Sharp & Dohme LLC·interventional·Posted Dec 20, 2023·Updated Mar 11, 2026

In Brief

A Phase 3 clinical trial evaluating V116 and PPSV23 for Pneumococcal Infection. Completed, enrolled 882 participants across 92 sites in 13 countries.

Detailed Summary

The purpose of this study is to evaluate the safety, tolerability, and immunogenicity of V116 compared to PPSV23 in children and teenagers 2 through 17 years of age, who had completed routine pneumococcal vaccine as infants/toddlers. Researchers want to learn if V116 is as good as, or is better than the PPSV23 vaccine in terms of the antibody immune response. V116 and PPSV23 will be studied in children and teenagers who have a higher risk of getting pneumococcal disease (PD).
