Geometric Mean Antibody Concentration (GMC) After Vaccination in 13vPnC Groups

GMC as measured by enzyme-linked immunosorbent assay (ELISA) for 7 common pneumococcal serotypes (serotypes 4, 6B, 9V, 14, 18C, 19F, and 23F) and 6 additional pneumococcal serotypes specific to 13vPnC (Serotypes 1, 3, 5, 6A, 7F, and 19A) are presented.

Time frame: 28 to 42 days after vaccination 3 for Group 1 (13 to <17 months of age), after vaccination 2 for Group 2 (14 to <26 months of age), and after vaccination 1 for Group 3 (26 to <73 months of age).

Population: The evaluable immunogenicity (per protocol) population was the primary analysis population consisting of eligible subjects who adhered to the protocol requirements, had valid and determinate assay results, and had no other major protocol violations.
