Seroconversion was assessed by means of enzyme immunoassay (EIA) for anti-pertussis toxoid (PT) and anti-filamentous hemagglutinin (FHA) antibodies. Seroconversion was defined as ≥ 4 fold increase in antibody titers from Day 0 to 30 days after the third vaccination.

Seroconversion for anti-pertussis toxoid and anti-filamentous hemagglutinin antibodies was assessed in the per-protocol population.

Immunogenicity was assessed by radioimmunoassay (RIA) for anti-hepatitis B (HBs) and anti-PRP antibodies, enzyme immunoassay (EIA) for anti-tetanus, serum neutralization (SN) for anti-diphtheria, and microneutralization for anti-polio type 1, 2, and 3 antibodies.

Seroprotection was defined as titers ≥ 10 mIU/mL for anti-Hepatitis Bs, ≥ 0.15 μg/mL for anti-PRP, ≥ 0.01 IU/mL for anti-tetanus and anti-diphtheria, and ≥ 8 1/dil for anti-polio types 1, 2, and 3 at 30 days after the third vaccination.

Seroprotection to the vaccine antigens was assessed in the per-protocol population.

Geometric mean titers to Tetanus antigen was assessed by means of enzyme immunoassay (EIA) before the first vaccination (at Day 0) and 1 month after the third vaccination (Day 150).

Geometric mean titers to the vaccine antigens were assessed in the per-protocol population.

Geometric mean titers to the Polio Antigens were assessed by means of microneutralization assay for anti-polio types 1, 2, and 3 before the first vaccination (at Day 0) and 1 month post-vaccination 3 (Day 150).

Geometric mean titers to the Polio Antigens were assessed in the per-protocol population.

Solicited injection site reactions - erythema, edema, induration, and pain were assessed in each participant at the DTaP-IPV-Hep B-PRP~T and PENTAXIM™ injection sites

Safety was assessed on the safety analysis (intent-to- treat) population.

Solicited injection site reactions - erythema, edema, induration, and pain were assessed in each participant at the DTaP-IPV-Hep B-PRP~T and ENGERIX B® injection sites.

Safety was assessed on the safety analysis (intend-to-treat) population.

Solicited systemic reactions: Pyrexia (temperature), Somnolence, Irritability, Anorexia, Vomiting not otherwise specified (NOS), Diarrhea NOS, and Crying were assessed in each participant following vaccination.

Grade 3 reactions defined as: Pyrexia (temperature), ≥ 39.1°C; Somnolence, sleeping most of the time; Irritability, continuously irritable for ≥ 3 hours; Anorexia, refused most or all feeds; Vomiting NOS, frequent vomiting and inability to have any oral intake; Diarrhea NOS, multiple liquid stools without any solid material; and Crying, persistent, inconsolable cry ≥ 3 hours and/or high-pitched cry.

Safety was assessed on the safety analysis (intent-to- treat) population.
