SECONDARY outcome

Timeframe: 1 month after vaccination

Population: Immunogenicity Evaluable Population included all subjects 50+ years who received study vaccine, with no major protocol deviation impacting immunogenicity assessment, no prohibited medication or vaccine, and provided evaluable serum sample results for baseline and Month 1 within required time frames. Data were analyzed according to vaccine received.

Antibody geometric mean concentrations as measured by IgG for the 31 pneumococcal serotypes in VAX-31.
