Description

Inclusion Criteria:

• Previously received three documented doses of diphtheria, tetanus, and whole-cell pertussis, hepatitis B vaccine (DTPwHepB), and a 3-dose course of oral polio vaccine and, if locally recommended, pneumococcal and rotavirus vaccines.

Exclusion Criteria:

• Child in care
• Use of a drug or vaccine that is not approved for that indication other than the study vaccines within 30 days preceding the first dose of study vaccine, or planned use during the study period.
• Any medical condition that in the judgment of the investigator would make intramuscular injection unsafe.
• Chronic administration of immunosuppressants or other immune-modifying drugs within six months prior to the first vaccine dose. For corticosteroids, this meant prednisone≥ 0.5 mg/kg/day, or equivalent. Inhaled and topical steroids were allowed.
• Planned administration/administration of a vaccine not foreseen by the study protocol in the period starting seven days before the first dose of SB257049 measles, rubella and YF vaccines and ending 42 days after the last dose of vaccines given at 9 months of age (Visit 4), with the exception of oral polio vaccine which could be given for unforeseen public health threat.
