Key inclusion & exclusion criteria

Inclusion criteria: Newborns on term of any sex, healthy, with normal history and clinical exam. Participating in a voluntary way (signing of the Informed Consent by the parents). Nutritional evaluation over the tenth percent (p10), so when born (weigh > 2500 gr ). Children from mothers with absence of surface antigen against the virus of hepatitis B during pregnancy. Not having received vaccines against Tetanus, Diphtheria, Whooping Cough, Hepatitis B or Haemophilus influenza previously to the initiation of the study or beyond the study, once initiated this.
Exclusion criteria: Presenting, when born, a diagnosis of any of the following conditions: congenital irregularity, endocrine-metabolic disease, convulsive encephalopathy, chronic disease involving the liver or the hemolymphopoietic, respiratory, or urogenital systems, etc. If the family plans to change home or move out of the locality during the period of duration of the study. Icteric disease of any origin (except physiological icterus) or acute hepatic disease. Allergy to any of the components of the vaccine (for instance, Tiomersal).

Age minimum: Suckling children of 6 week at moment of 1st dose.
Age maximum: Suckling children of 10 week at moment of 1st dose
Gender: Both

Health Condition(s) or Problem(s) studied

Prophylaxis against infections diseases: Diphtheria, Tetanus, B. pertussis, H. influenzae type b and hepatitis B.

Intervention(s)

Group I (study): Received the combined DPT-HB-Hib vaccine (liquid). 0.5 mL. Group II (control): Received the commercial combined DPT-HB+Hib vaccine (Heberpenta). 0.74 mL. Both groups received the vaccine by intramuscular route, with a schedule of 2-4-6 months

Primary Outcome(s)

Safety: Measuring time: 1 hour, 24, 48 and 72 hours and 7 and 30 days after each dose. Measured as: Local Events (Erythema, Induration, Pain, Infiltration, abscess) and Sistemic Events (Fever, feverish, irritability, vomits, persistent crying, anaphylactic shock).

Secondary Outcome(s)

Immunogenicity: Measuring time: 30 days after the 3rd dose (last dose). Measured as: Anti-HBsAg titres = 10 IU/L, and % of hyper-response (anti-HBsAg titres = 100 IU/L). Titres against the diphtheria and tetanic toxoids = 0.1 IU/mL, Titres anti-B. pertussis specific = 11 UN (Novatec Units) to the value of cut of the determination. Titres anti-PRP of Hib = 0.15 µg/mL and = 1.0 µg/mL long term protection.
