Subjects will be randomly assigned to 1 of 3 groups to receive the following vaccines: Group 1: 13-valent pneumococcal conjugate vaccine (13vPnC) and diphtheria, tetanus, and acellular pertussis vaccine (DTaP), Group 2: 7-valent pneumococcal conjugate vaccine (7vPnC) and DTaP, Group 3: DTaP alone. Group 3 subjects will also receive catch-up doses of Prevenar (commercial product of Prevenar in Japan) 13vPnC and 7vPnC will be blinded, and DTaP will be open-label. The main purpose of the study is to determine if the immune responses to 13vPnC are comparable to the immune responses to 7vPnC and if the immune responses to 13vPnC given with DTaP are comparable to those induced by DTaP given alone. In addition, the study aims to evaluate the side effects (safety profile) after vaccination of 13vPnC and 7vPnC when given with DTaP in healthy Japanese infants.

Percentage of Participants Achieving Serotype-specific Pneumococcal Immunoglobulin G (IgG) Antibody Level Greater Than or Equal to (>=) 0.35 Microgram Per Milliliter (mcg/mL) 1 Month After the Infant Series
Percentage of participants achieving predefined antibody threshold \>=0.35 mcg/mL along with the corresponding 95% confidence interval (CI) for the 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. Exact 2-sided CI based on the observed proportion of participants. To demonstrate non-inferiority, for 6 additional serotypes in 7vPnC + DTaP group, the lowest response observed among the 7 common serotypes in the group was taken as reference.
Time frame: 1 month after the infant series
Geometric Mean Concentration (GMC) of Serotype-specific Pneumococcal Immunoglobulin G (IgG) Antibody for 7 Common Serotypes 1 Month After the Infant Series
Antibody geometric mean concentration (GMC) for 7 common pneumococcal serotypes (serotypes 4, 6B, 9V, 14, 18C, 19F, and 23F) 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
Percentage of Participants Achieving Predefined Antibody Levels for Diphtheria Toxoid, Tetanus Toxoid, and Pertussis Antigens 1 Month After the Infant Series
Predefined antibody levels were 0.1 International Units/mL (IU/mL) for diphtheria, 0.01 IU/mL for tetanus, 5 Enzyme-linked Immunosorbent Assay (ELISA) units/mL (EU/mL) for pertussis toxoid (PT), and 5 EU/mL for filamentous hemagglutinin (FHA).
Time frame: 1 month after the infant series
Geometric Mean Concentration (GMC) of Serotype-specific Pneumococcal Immunoglobulin G (IgG) Antibody for 6 Additional Serotypes 1 Month After the Infant Series
Antibody GMC for 6 additional pneumococcal serotypes specific to 13vPnC (Serotypes 1, 3, 5, 6A, 7F, and 19A) are presented. GMC (13vPnC) and corresponding 2-sided 95% CIs were evaluated. GMs were calculated using all participants with available data for the specified blood draw. To demonstrate non-inferiority, for 6 additional serotypes in 7vPnC + DTaP group, the lowest GMC observed among the 7 common serotypes in the group was taken as reference.
Time frame: 1 month after the infant series
Percentage of Participants Achieving Serotype-specific Pneumococcal Immunoglobulin G (IgG) Antibody Level >=0.35 mcg/mL 1 Month After the Toddler Dose
Percentage of participants achieving predefined antibody threshold \>=0.35 mcg/mL along with the corresponding 95% CI for the 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. Exact 2-sided CI based on the observed proportion of participants. To demonstrate non-inferiority, for 6 additional serotypes in 7vPnC + DTaP group, the lowest response observed among the 7 common serotypes in the group was taken as reference.

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.
