The purpose of this observer-blind study is to generate immunogenicity data with one formulation of GSK Biologicals' DTPw-HBV/Hib vaccine after the primary vaccination course and to demonstrate non-inferiority of this vaccine as compared to two formulations of GSK Biologicals' DTPw-HBV/Hib vaccine with respect to the anti-PRP antibody response. Additionally to assess the reactogenicity and safety of GSK Biologicals' DTPw-HBV/Hib vaccine. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.

Number of Seroprotected Subjects Against Polyribosyl-ribitol-phosphate (PRP) Antigens
A seroprotected subject was defined as a subject with anti-PRP concentrations greater than or equal to (≥) 0.15 microgram per milliliter (µg/mL).
Time frame: At Month 3
Number of Seroprotected Subjects Against Hepatitis B Surface Antigen (HBs)
A seroprotected subject is defined as a vaccinated subject with anti-hepatitis B antibody concentration greater than or equal to (≥) 10 milli-international units per milliliter (mIU/mL).
Time frame: At Month 3
Number of Seroprotected Subjects Against Diphtheria (D) and Tetanus (T) Antigen
A seroprotected subject is defined as a vaccinated subject with anti-D and anti-T antibody concentrations greater than or equal to (≥) 0.1 international units per milliliter (IU/mL). Seroprotection was assesed via enzyme-linked immunosorbent assay (ELISA).
Time frame: At Month 3
Number of Seroprotected Subjects Against Diphteria (D) With Antibody Concentrations Above the Cut-off
Seroprotection cut-off values assessed were greater than or equal to (≥) 0.016 international units per milliliter (IU/mL) in the sera of subjects seronegative before vaccination. Concentrations were assessed via neutralization assay on Vero cells.
Time frame: At Month 3
Number of Seropositive Subjects Against Polyribosyl-ribitol-phosphate (PRP) Antigens
Seropositivity was defined as antibody concentrations greater than or equal to (≥) 1 microgram/milliliter (µg/mL).
Time frame: At Month 3
Number of Seropositive Subjects Against Bordetella Pertussis (BPT) Antigen
A seropositive subject was defined as a vaccinated subject with anti-BPT antibody concentration greater than or equal to (≥) 15 ELISA units (EL.U) per milliliter (EL.U/mL).
Time frame: At Month 3
Number of Subjects With Vaccine Response to Bordetella Pertussis (BPT) Antigen
Vaccine response was defined as: for initially seronegative subjects, antibody concentration greater than or equal to (≥) 15 EL.U/mL; and for initially seropositive subjects, antibody concentration ≥ 1 fold the pre-vaccination antibody concentration.
Time frame: At Month 3
Concentration of Antibodies Against Polyribosyl-ribitol-phosphate (PRP) Antigens
Concentrations are presented as geometric mean concentrations (GMCs), expressed in micrograms per milliliter (μg/mL).
Time frame: At Month 3
Concentration of Antibodies Against Diphtheria (D) and Tetanus (T) Antigens
Concentrations are presented as geometric mean concentrations (GMCs), expressed in international units per milliliter (IU/mL).
Time frame: At Month 3
Concentration of Antibodies Against Hepatitis B Surface Antigen (HBs)
Concentrations are presented as geometric mean concentrations (GMCs), expressed in milli-international units per milliliter (mIU/mL).
Time frame: At Month 3
Concentration of Antibodies Against Bordetella Pertussis (BPT) Antigen
Concentrations are presented as geometric mean concentrations (GMCs), expressed in ELISA units per milliliter (EL.U/mL).
Time frame: At Month 3
Number of Subjects With Any and Grade 3 Solicited Local Symptoms
Assessed solicited local symptoms were pain, redness and swelling. Any = occurrence of any local symptom regardless of intensity grade. Grade 3 pain = cried when limb was moved/spontaneously painful. Grade 3 redness/swelling = redness/swelling spreading beyond 20 millimeters (mm) of injection site.
Time frame: During the 4-day (Day 0-3) follow-up period post-vaccination
Number of Subjects With Any, Grade 3 and Related Solicited General Symptoms
Assessed solicited general symptoms were drowsiness, fever \[defined as axillary temperature equal to or above (≥) 37.5 degrees Celsius (°C)\], irritability and loss of appetite. Any = occurrence of any general symptom regardless of intensity grade. Grade 3 Irritability= crying that could not be comforted/prevented normal activity. Grade 3 Drowsiness/Loss of appetite= Drowsiness/Loss of appetite that prevented normal activity. Grade 3 fever = fever above (\>) 39.5°C. Related = symptom assessed by the investigator as related to the vaccination.
Time frame: During the 4-day (Day 0-3) follow-up period post-vaccination
Number of Subjects With Any Unsolicited Adverse Events (AEs)
An unsolicited AE covers any untoward medical occurrence in a clinical investigation subject temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product and reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms. Any was defined as the occurrence of any unsolicited AE regardless of intensity grade or relation to vaccination.
Time frame: During the 31-day (Day 0-30) follow-up period post-vaccination
Number of Subjects With Serious Adverse Events (SAEs)
Serious adverse events (SAEs) assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization or result in disability/incapacity.
Time frame: During the entire study period (Day 0-Month 3)
