Primary Outcome Measures:
  • Number of Subjects Seroconverted for Anti-rotavirus Immunoglobulin A [ Time Frame: One month after the second vaccine dose ] [ Designated as safety issue: No ]
    Seroconversion is defined as the appearance of antibodies with concentrations greater than or equal to 20 units per milliliter (U/mL) in the serum of subjects seronegative before vaccination.

Secondary Outcome Measures:
  • Serum Anti-rotavirus Immunoglobulin A Antibody Concentrations [ Time Frame: One month after the second vaccine dose ] [ Designated as safety issue: No ]
    Concentrations are given as Geometric Mean Concentrations (GMCs). Note: In the Placebo Group the value was below the assay cut-off (20 units per milliliter).

  • Number of Subjects Reporting Solicited Symptoms [ Time Frame: During the 8-day (Day 0 - Day 7) follow-up period after each vaccine dose. ] [ Designated as safety issue: No ]
    Solicited symptoms assessed include cough, diarrhoea, irritability, loss of appetite , fever and vomiting.

  • Number of Subjects Reporting Unsolicited Adverse Events (AEs) [ Time Frame: During the 31-day (Day 0 - Day 30) follow-up period after each vaccine dose ] [ Designated as safety issue: No ]
    Unsolicited AE covers any AE reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms.

  • Number of Subjects Reporting Serious Adverse Events (SAEs) [ Time Frame: Throughout the study period (2-3 months). ] [ Designated as safety issue: No ]
    SAEs assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization, result in disability/incapacity or are a congenital anomaly/birth defect in the offspring of a study subject.

  • Number of Subjects Reporting Rotavirus Gastroenteritis Episode(s) [ Time Frame: From Dose 1 up to 1 month after Dose 2. ] [ Designated as safety issue: No ]

Enrollment: 684

Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • Subjects who the investigator believes that their parents/guardians can and will comply with the requirements of the protocol should be enrolled in the study.
  • A male or female between, and including, 6 to 12 weeks of age at the time of the first dose of the vaccination.
  • Written informed consent obtained from the parents or guardians of the subject.
  • Healthy subjects as established by medical history and clinical examination before entering into the study.

  • Chronic administration (defined as more than 14 days) of immunosuppressants or other immune-modifying drugs since birth.
  • Planned administration/ administration of a vaccine not foreseen by the study protocol within 30 days of the first dose of vaccine with the exception of the routine infant vaccines.
  • Concurrently participating in another clinical study, at any time during the study period, in which the subject has been or will be exposed to an investigational or a non-investigational product.
  • Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination.
  • Any clinically significant history of chronic gastrointestinal disease including any uncorrected congenital malformation of the gastrointestinal tract or other serious medical condition as determined by the investigator.
  • History of allergic disease or reactions likely to be exacerbated by any component of the vaccine.
  • Acute disease at the time of enrolment.
  • Administration of immunoglobulins and/or any blood products since birth or planned administration during the study period.
