E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
•In all subjects, to determine if two doses of GSK Biologicals’ HRV vaccine given concomitantly with routine vaccinations* can prevent severe rotavirus gastroenteritis (RV GE) caused by the circulating wild-type RV strains during the period starting from 2 weeks after Dose 2 until 2 years of age. (*Whenever Oral Polio Vaccination (OPV) is used a minimum 2-week interval should be observed between HRV vaccine and OPV doses.)
•In all subjects, to assess the safety of HRV vaccine with respect to definite intussusception (IS) within 31 days (Day 0-Day 30) after each HRV vaccine dose.

|
E.2.2 | Secondary objectives of the trial |
HRV vac. efficacy and if 2 doses can prevent severe RV GE caused by the wild type G1, non-G1, & each non-G1 types, and severe GE, from 2 weeks after dose 2 up to 2 years and 3 years of age
If 2 doses of HRV vac. can prevent RV GE caused by the circulating wild-type RV strains & requiring hospitalization & re-hydration therapy in a medical facility, up to 2 & 3 years of age
If 2 doses of HRV vac. can prevent RV GE caused by the circulating wild-type RV strains during the period starting from 2 weeks after Dose 2 until one year of age
safety of HRV vac. in terms of occurrence of serious adverse events (SAEs) from Dose 1 until Visit 5 & in terms of occ. of related SAEs until study end
Safety of HRV vac. in terms of occ. of definite IS during the period starting from Dose 1 until 2 years
Mortality up to the age of 2 years
In a subset of 100 subjects per country, to assess the immunogenicity of HRV vac. in terms of RV IgA antibody titres 1 or 2 months after 2nd study vac. dose
