The purpose of this study will be to evaluate safety, tolerability and immunogenicity of three lots of 13-valent pneumococcal vaccine given to healthy infants. Lots will be studied for consistency of the immune response, as well as for non-inferiority and safety as compared to 7-valent Pneumococcal Conjugate Vaccine.

Geometric Mean Concentration (GMC) for Serotype-specific Pneumococcal Immunoglobulin G (IgG) Antibody in the Three 13vPnC Groups 1 Month After the Infant Series
Antibody geometric mean concentration (GMC) as measured by micrograms per milliliter (mcg/mL) 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. GMC (13vPnC) and corresponding 2-sided 95% confidence intervals (CI) were evaluated. Geometric means (GMs) were calculated using all participants with available data for the specified blood draw.
Time frame: 1 Month after the infant series (7 Months of age)
Percentage of Participants Achieving Predefined Antibody Level ≥0.1 International Units Per Milliliter (IU/mL) for Tetanus Toxoid in the Combined 13vPnC Group Relative to 7vPnC Group 1 Month After the Infant Series
Percentage of participants achieving predefined antibody threshold ≥0.1 IU/ mL along with the corresponding 95% CI for concomitant antigen tetanus toxoid are presented. Exact 2-sided CI was based on the observed proportion of participants. Combined 13vPnC group includes participants randomized to pilot lot 1, pilot lot 2, or the manufacturing lot.
Time frame: 1 month after the infant series (7 months of age)
Percentage of Participants Achieving Predefined Antibody Level ≥1:8 for Poliovirus in the Combined 13vPnC Group Relative to 7vPnC Group 1 Month After the Infant Series
Percentage of participants achieving predefined antibody threshold ≥1:8 along with the corresponding 95% CI for concomitant antigen poliovirus type 1, type 2, and type 3 (Sabin strains 1, 2, 3) are presented. Exact 2-sided CI was based on the observed proportion of participants. Combined 13vPnC group includes participants randomized to pilot lot 1, pilot lot 2, or the manufacturing lot.
Time frame: 1 month after the infant series (7 months of age)
Percentage of Participants Achieving Predefined Antibody Level ≥10.0 Milli-International Units Per Milliliter (mIU/mL) for Hepatitis B in the Combined 13vPnC Group Relative to 7vPnC Group 1 Month After the Infant Series
