Title: Double-Blind Randomized Placebo-Controlled Dose Escalating Phase Ib/IIa Study to Evaluate the Safety and Immunogenicity of Live Attenuated Oral Rotavirus Vaccine 116E in Healthy Non-Malnourished Infants 8 to 20 Weeks of Age
Brief Summary: This study will be a Phase I, randomized, double blind, safety and immunogenicity trial of the Vero cell based 116E neonatal rotavirus vaccine candidate strain in healthy non-malnourished infants aged 8-20 weeks at three different dosage levels i.e.10\^4.0, 10\^5.0 and 10\^6.0 FFU and for three administrations of each of these dosages given to infants at 4-week intervals. 180 infants (90 vaccinees/90 placebo) will be enrolled for each of the three dosage levels. The progression from the lower to the next higher dosage will be based on approval by the Data Safety Monitoring Board (DSMB) to be constituted by the Department of Biotechnology, New Delhi.

  * Fever is defined as temperature ≥ 37.5°C /99.5°F on oral, axillary or tympanic setting, or ≥ 38.0°C /100.4°F on rectal setting.
  * Subjects with a minor illness without fever may be enrolled at the discretion of the investigator.
