The main objectives of this study are to determine vaccine efficacy against severe rotavirus (RV) gastroenteritis (GE) during the period starting from 2 weeks after Dose 2 until two years of age and to determine the safety of GSK Biologicals' HRV vaccine with respect to definite intussusception (IS) within 31 days (Day 0-Day 30) after each HRV vaccine dose.

Further study details as provided by GlaxoSmithKline:

Primary Outcome Measures:
  • Occurrence of severe RV GE caused by the wild RV strains from 2 weeks after Dose 2 until two years of age. Occurrence of definite IS cases within 31 days (Day 0 -Day 30) after each HRV vaccination dose. [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Severe RV GE by wild-type G1, non-G1, each non-G1 and severe GE from 2 weeks after Dose 1 and 2 until 2-year old. SAEs. Mortality. Definite IS until 2-years old. Serum anti-RV IgA at Visits 1 and 3 (100 subjects/country). [ Designated as safety issue: No ]

Detailed Description:

The study has two groups: Group HRV and Group Placebo. Two oral doses administered to healthy infants who are 6-12 weeks of age in Hongkong and Taiwan or 11-17 weeks of age in Singapore, according to a 0, 1 to 2-month schedule. Routine vaccinations are given concomitantly with the study vaccines at 2 or 3 and 4 months of age according to each local country regulation. Whenever OPV is used, a minimum 2-week interval should be observed between HRV vaccine and OPV doses.
