In Brief

A Phase 3 clinical trial evaluating V110, V114, and 3 other interventions for Pneumococcal Infection. Completed, enrolled 850 participants across 46 sites in 2 countries.

Detailed Summary

The purpose of this study is to evaluate the concomitant and non-concomitant use of messenger ribonucleic acid (mRNA) mRNA-1273, the nucleoside-modified mRNA vaccine for active immunization to prevent coronavirus disease (COVID-19) caused by severe acute respiratory syndrome coronavirus (SARS-CoV-2), with a 23-valent pneumococcal polysaccharide vaccine (V110) for the prevention of pneumococcal disease, or a 15-valent pneumococcal conjugate vaccine (V114) indicated for the prevention of invasive pneumococcal disease.
