PRIMARY outcome

Timeframe: From Day 0 up to 1 month after Dose 2 of Rotarix vaccine/Placebo

Population: The analyses were performed on the Total Vaccinated Cohort that included all the subjects with at least one study vaccine or placebo administration documented.

An SAE is any untoward medical occurrence that: results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect in the offspring of a study subject, or may evolve into one of the outcomes listed above.

Timeframe: At Visit 3, 1 month after Dose 2 of Rotarix vaccine/Placebo

Population: The analyses were performed on the According-to-Protocol immunogenicity cohort that included all subjects with at least one study vaccine or placebo administered, for whom immunogenicity data were collected and available and who complied with the inclusion criteria defined in the protocol.

Number of subjects with anti-rotavirus IgA antibody concentration ≥ 20 Units/milliliter (U/mL).

SECONDARY outcome

Timeframe: At Visit 3, 1 month after Dose 2 of Rotarix vaccine/Placebo

Population: The analyses were performed on the According-to-Protocol immunogenicity cohort. The anti-rotavirus IgA antibody GMC for Placebo Group was below the assay cut-off (\<20 U/mL), so could not be computed.

Anti-rotavirus IgA antibody concentrations are given as geometric mean concentrations (GMC) with 95% Confidence Intervals, calculated on all subjects.
