This study is designed to evaluate in a controlled manner the effect of Prevnar® on the immune responses of Pentacel™
Primary Objective - Stage I:
To compare the immune responses elicited by an infant series of Pentacel™ when given at different times from or concurrently with a Pneumococcal conjugate vaccine (Prevnar®).
Primary Objective - Stage II:
To compare the immune responses elicited by a 4th dose of Pentacel™ when given at different times from or concurrently with Prevnar®.

Diphtheria Tetanus Haemophilus Infection Pertussis Polio | Biological: Pentacel™: HCPDT-IPV//PRP-T Vaccine and Prevnar® | Phase 3 |
This is a 2-staged study. Stage I of this study is designed to compare the immune responses elicited by an infant series (3 doses) of Pentacel™ when given at different times from or concurrently with Prevnar®.
Stage II is designed to describe the immune responses elicited by a 4th dose of Pentacel™ (all antigens) when given at different times from or concurrently with Prevnar®.

- Percentage of Participants With 4-fold Rises in Levels of Pentacel™ Vaccine Antibody Titers Post-dose 3 When Given at Different Times or Concurrently With a Pneumococcal Conjugate Vaccine (Prevnar®) [ Time Frame: 28 to 48 days post-3rd vaccination ]Seroconversion was defined as the percentage of subjects with ≥ 4-fold post-dose 3 for anti-pertussis and ≥ 0.15 μg/mL or ≥ 1.0 μg/mL for anti-Polyribosylribitol Phosphate (PRP) responses.
- Geometric Mean Titers of Antibodies to Pertussis, Diphtheria, Tetanus, Polyribosylribitol Phosphate and Poliovirus Elicited by an Infant Series of Pentacel™ When Given at Different Times or Concurrently With a Pneumococcal Conjugate Vaccine (Prevnar®) [ Time Frame: 60 Days Post-dose 3 ]Anti-pertussis response include antibodies to Pertussis Toxoid (PT); Filamentous Haemagglutinin (FHA); Fimbriae Types 2 and 3 (FIM) and Pertactin (PRN) antigens.
- Percentage of Subjects With Solicited Local, Systemic Reactions Occurring Between 0-3 Days After Each Dose of Pentacel™ [ Time Frame: 0-3 days post- vaccination and entire study period ]Solicited local reactions: redness, swelling, and tenderness. Solicited systemic reactions: fever (temperature), irritability post-vaccinal, crying, lethargy, appetite decreased, vomiting, diarrhea, and rash.
