Title: A Multicenter Study of the Immunogenicity & Safety of 2 Doses of GSK Biologicals' Oral Live Attenuated Human Rotavirus Vaccine (RIX4414) as Primary Dosing of Healthy Infants in India Aged Approximately 8 Wks at the Time of the First Dose
Brief Summary: Rotavirus disease is the most common cause of gastroenteritis and dehydration in young children worldwide. The global public health burden has prompted the development of a human rotavirus vaccine against rotavirus disease by GlaxoSmithKline Biologicals. This pre-registration study is undertaken to provide immunogenicity, reactogenicity and safety data for the vaccine when used in Indian infants aged approximately 8 weeks at the time of the first dose.


Options:
A: Inclusion Criteria:

* A diagnosis or suspicion of immunodeficiency disorder (either in the infant or in a member of the immediate family).
* A diagnosis or suspicion of bleeding disorder that would contraindicate venipuncture.
* Acute diarrhea, infection or illness at the time of the first visit (6 weeks of age) that would require infant's admission to a hospital or would contraindicate provision of OPV per country guidelines.
* Acute vomiting and intolerance to liquids within 24 hours before the first visit (6 weeks of age).
* Receipt of OPV or IPV at any time before enrollment based upon mother's recall or immunization card if available.
* Because of contact transmission of vaccine poliovirus strains, newborns from multiple births will be excluded from the study to prevent transmission of vaccine strains received during routine immunization from the twin to the study participant.

* Chronic administration (defined as more than 14 days) of immunosuppressants or other immune-modifying drugs since birth. (For corticosteroids, this will mean prednisone, or equivalent, \>= 0.5 mg/kg/day. Inhaled and topical steroids are allowed.)
* Any chronic drug therapy to be continued during the study period.
* Administration of a vaccine not foreseen by the study protocol within 6 weeks of the first dose of vaccine or planned administration during the study of a vaccine not foreseen by the study protocol, with the exception of diphtheria, tetanus, pertussis, hepatitis B, Haemophilus influenzae type b (Hib), OPV and vaccination against tuberculosis, which can be given with at least two weeks separation from the first and subsequent dose of the study vaccine.
* Prior administration of experimental rotavirus vaccine.
* History of confirmed rotavirus gastroenteritis.
* 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 human immunodeficiency virus (HIV) infection based on physical examination (no laboratory testing is required).
* A family history of congenital or hereditary immunodeficiency.
* History of allergic disease or reactions likely to be exacerbated by any component of the vaccine.
* Major congenital defects or serious chronic illness.
* History of any neurologic disorders or seizures.
* Acute disease at the time of enrolment.
* Gastroenteritis (diarrhea) within 7 days preceding the study vaccine administration (warrants deferral of the vaccination).
* Acute or chronic, clinically significant pulmonary, cardiovascular, hepatic or renal functional abnormality, as determined by physical examination or medical history.
* Administration of immunoglobulins and/or blood products since birth or planned administration during the study period. Oral intake of immunoglobulins via breastfeeding is allowed.
C: Inclusion Criteria:

* infants aged 6 to 12 weeks
* born in Brest District, France
* born between Feb 01, 2007 and Nov 19, 2009
