Brief Summary: The objective of the study is to evaluate the safety and tolerability of a single injection of VAX-24 at 3 dose levels compared to Prevnar 20™ (PCV20) in adults 18 to 49 years of age in Phase 1. The Phase 2 will evaluate the safety, tolerability, and immunogenicity of a single injection of VAX-24 at 3 dose levels compared to PCV20 in adults aged 50 to 64 years of age in Phase 2.
Detailed Description: The objective of the study is to evaluate the safety and tolerability of a single injection of VAX-24 at 3 dose levels (Low: 1.1 mcg; Mid: 2.2 mcg; or Mixed: 2.2/4.4 mcg) compared to Prevnar 20™ (PCV20) in adults 18 to 49 years of age in Phase 1. The Phase 2 will evaluate the safety, tolerability, and immunogenicity of a single injection of VAX-24 at 3 dose levels (Low: 1.1 mcg; Mid: 2.2 mcg; or Mixed: 2.2/4.4 mcg) compared to PCV20 in adults aged 50 to 64 years of age.
