Primary Outcome Measures:
  • Pneumococcal Opsonophagocytic Activity (OPA) Geometric Mean Titers (GMTs) for the 13 Serotypes 1 Month After Vaccination for Overall Population [ Time Frame: 1 month after vaccination ] [ Designated as safety issue: No ]
    Serotype-specific antibody-mediated opsonophagocytic activity (functional antibodies) for the 13 pneumococcal serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) as measured by a quantitative opsonophagocytic activity assay (OPA). OPA titers will be logarithmically transformed for analysis; geometric means calculated and expressed as geometric mean titers (GMTs). The 2-sided, 95% confidence intervals (CIs) on the GMTs were constructed by back transformation of the CIs for the mean of the logarithmically transformed assay results computed using the Student t distribution.
