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.
