Brief Summary: The trial is a phase III randomized, double-blind, placebo-controlled trial with the primary objective of evaluating the efficacy of three doses of ORV 116E, 10\^5.0 FFU, against severe rotavirus gastroenteritis, in comparison with a placebo in India.

B: Inclusion Criteria:

* Male or female infants who are at least 6 weeks of age and no more than 14 weeks, 6 days of age at Visit 1.

* Parents/legal guardians able to complete all relevant study procedures during study participation.

Exclusion Criteria:

* Any clinically significant history of gastrointestinal disease including abdominal surgery or liver disease or other serious medical conditions as determined by the site investigator.
* Any history of immunodeficiency in the infant (e.g., the infant is known to be human immunodeficiency virus (HIV) positive, to have hypogammaglobulinemia, or to have an underlying malignancy), or any infant with any unvaccinated household contact who is immunocompromised such as:

* Less than 37 weeks gestation at birth.
* Receipt of blood and/or blood products (including immunoglobulin) within 4 weeks before vaccine administration.
* Receipt of live vaccine within the past 30 days or a nonreplicating, inactivated, or subunit vaccine within the last 14 days, although planned licensed trivalent inactivated influenza vaccine that may be administered to children over 6 months of age during a routine clinic visit is permitted and would not be exclusionary.

* Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination (no laboratory testing required).
