Brief summary: To assess the efficacy, immune response and safety of 2 doses of HRV vaccine (at different concentrations) in healthy infants aged approximately 3 months previously uninfected with human rotavirus.


Eligibility criteria: Inclusion Criteria:

* Healthy infants 11 and 17 weeks of age at the time of the first vaccination, born after a normal gestation period (between 36 and 42 weeks).
* Written informed consent obtained from the parents or guardians of the subject.

Exclusion Criteria:

* Use of any investigational or non-registered drug or vaccine other than the study vaccine(s) within 30 days preceding the first dose of study vaccine, or planned use during the study period.
* Previous vaccination against or history of or intercurrent diphtheria, tetanus, pertussis, polio and/or Hib.
* Chronic administration of immunosuppressants or other immune-modifying drugs since birth. (Topical steroids are allowed.)
* Use of antibiotics during the period starting from 7 days before each dose of vaccine(s) and ending 7 days after.
* Any clinically significant history of chronic gastrointestinal disease including any uncorrected congenital malformation of the GI tract or other serious medical condition as determined by the investigator.
* Any confirmed or suspected immunosuppressive or immunodeficient condition, including HIV infection.
* History of allergic disease or reaction likely to be exacerbated by any component of the vaccine.
* GE within 7 days preceding the study vaccine administration (warrants deferral of the vaccination).
* Household contact with an immunosuppressed individual or pregnant woman.
* Administration of immunoglobulins and/or blood products since birth or planned administration during the study period.
* Previous confirmed occurrence of RV GE.
