Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Healthy infants between, and including, 5-10 weeks of age at the time of the first dose of HRV liquid vaccine or placebo.
  • Birth weight of the subject should be > 2000 grams.
  • Written informed consent obtained from the parent or guardian of the subject.

Exclusion criteria

  • Use of any investigational or non-registered product (drug or vaccine) other than the study vaccine within 30 days preceding the first dose of study vaccine, or planned use during the study period.
  • Chronic administration of immunosuppressants or other immune-modifying drugs within six months prior to the first vaccine dose.
  • Planned administration/ administration of a vaccine not foreseen by the study protocol except for DTPw, HBV and OPV vaccines within 14 days before each dose of HRV liquid vaccine or placebo and ending 14 days after. BCG is administered at birth according to the local EPI.
  • Concurrently participating in another clinical study, at any time during the study period.
  • Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination (no laboratory testing required).
  • History of allergic disease or reactions likely to be exacerbated by any component of the HRV liquid vaccine or placebo.
  • Acute disease at the time of enrolment.
  • Administration of immunoglobulins and/or any blood products since birth or planned administration during the study period.

Primary outcomes

  1. Number of Seroconverted Subjects for Anti-rotavirus (Anti-RV) Immunoglobulin A (IgA) Antibody

    Time frame: At Month 3

    Seroconversion was defined as the appearance of anti-RV IgA antibody concentrations greater than or equal to (≥) 20 units per milliliter (U/mL) in subjects initially (i.e. prior to the first dose of Rotarix™ vaccine or placebo) seronegative, when administered concomitantly with the second and third routine EPI immunization. This outcome measure only concerns subjects in the Placebo-Rotarix-Rotarix Group.

Secondary outcomes

  1. Number of Seroconverted Subjects for Anti-RV IgA Antibody

    Time frame: At Month 3

    Seroconversion was defined as the appearance of anti-RV IgA antibody concentrations ≥ 20 U/mL in subjects initially (i.e. prior to the first dose of Rotarix™ vaccine or placebo) seronegative, when administered concomitantly with the first and third routine EPI immunization. This outcome measure only concerns subjects in the Rotarix-Placebo-Rotarix Group.

  2. Serum IgA Antibody Concentrations Against Rotavirus

    Time frame: At Month 3

    Antibody concentrations were presented as geometric mean concentrations (GMCs), expressed in units per milliliter (U/mL). This outcome measure only concerns subjects in Placebo-Rotarix-Rotarix and Rotarix-Placebo-Rotarix Groups.

  3. Number of Subjects Reporting Grade 2 or Grade 3 Fever, Vomiting or Diarrhea

    Time frame: During the 8-day (Days 0-7) period following each dose of study vaccine or placebo and across doses

    Any symptom = occurrence of the symptom (i.e. fever or vomiting or diarrhea) regardless of intensity grade or relationship to vaccination. Grade 2 fever = rectal temperature greater than (>) 38.5 - less than or equal to (≤) 39.5degrees Celsius (°C) or axillary temperature > 38.0 - ≤ 39.0°C. Grade 3 fever = rectal temperature > 39.5°C or axillary temperature > 39.0°C. Grade 2 vomiting = 2 episodes of vomiting/ day. Grade 3 vomiting = 3 or more episodes of vomiting/ day. Grade 2 diarrhea = 4-5 looser than normal stools/ day. Grade 3 diarrhea = 6 or more looser than normal stools/ day.

  4. Number of Subjects Reporting Any, Grade 3 and Related Solicited General Symptoms

    Time frame: During the 8-day (Days 0-7) period following each dose of study vaccine or placebo and across doses

    Assessed solicited general symptoms were cough/runny nose, diarrhea, fever (rectally), irritability, loss of appetite and vomiting. Any = any solicited symptom irrespective of intensity grade or relationship to vaccination. Grade 3 cough/runny nose = cough/runny nose which prevented daily activity. Grade 2 diarrhea: 4-5 looser than normal stools/ day. Grade 3 diarrhea = ≥ 6 looser than normal stools/ day. Grade 3 irritability = crying that could not be comforted/ prevented normal activity. Grade 3 loss of appetite = not eating at all. Grade 2 vomiting= 2 episodes of vomiting/ day. Grade 3 vomiting = ≥ 3 episodes of vomiting/ day. Related = symptom considered by the investigator to have a causal relationship to study vaccination.

  5. Number of Subjects Reporting RV in Gastroenteritis (GE) Episodes

    Time frame: From Dose 1 of study vaccine or placebo (at Day 0) up to Month 3

    Presence of RV (vaccine strain or wild-type) in GE stools.

  6. Number of Subjects Reporting Any Unsolicited Adverse Event (AE)

    Time frame: During the 31-day (Days 0-30) period following any study vaccine dose or placebo

    An unsolicited AE covers any untoward medical occurrence in a clinical investigation subject temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. Any was defined as an adverse event (AE) reported in addition to those solicited during the clinical study. Any solicited symptom with onset outside the specified period of follow-up for solicited symptoms was reported as an unsolicited adverse event.

  7. Number of Subjects With Serious Adverse Events (SAEs)

    Time frame: During the entire study period (from Day 0 to Month 3)

    Serious adverse events (SAEs) assessed include any untoward medical occurrences that results in death, are life threatening, requires hospitalization or prolongation of hospitalization, result in disability/incapacity or congenital anomaly/birth defect in the offspring of a study subject.
