Brief Summary:
This study will evaluate the safety, tolerability and immunogenicity of study vaccines 13vPnC and 23vPS in older, healthy subjects who have previously received a dose of 23vPS at least 5 years ago. It will also evaluate the safety, tolerability and immunogenicity to a dose of 13vPnC 1 year after the initial dose of study vaccine.

Primary Outcome Measures :
- Pneumococcal OPA Geometric Mean Titers (GMTs) for the 12 Common Serotypes for 13vPnC Relative to 23vPS (Vax 1 / Year 0) [ Time Frame: 1 month after Vax 1 / Year 0 ]Antibody geometric mean titers as measured by opsonophagocytic activity (OPA) assays for the 12 common serotypes (serotypes 1, 3, 4, 5, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F). Confidence intervals (CI) for the GMTs are back transformations of a CI based on the Student t distribution for the mean logarithm of the titers.

Exact 2-sided CI (Clopper and Pearson) based upon the observed percentage of participants.
Secondary Outcome Measures :
