Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is designed to evaluate the safety, tolerability, and immunogenicity of two investigational pneumococcal vaccines at three dose levels in healthy adults.

Primary Objective:

\- To evaluate the safety and tolerability of two investigational pneumococcal vaccines.

Observational Objective:

\- To evaluate the immunogenicity of the investigational pneumococcal vaccines.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

An initial cohort of 6 participants will receive a single dose of one of two investigational pneumococcal vaccines. After safety evaluation of that cohort, additional cohorts will receive 2 injections 30 days apart of same investigational pneumococcal vaccine at same or increased dose level. All participants will be monitored for safety for 30 days after each vaccination.
