Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to explore horizontal transmission of the HRV (Human Rotavirus) vaccine strain within a family from the twin vaccinated with Rotarix to the twin receiving placebo. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a Phase 3b study. Three doses of Infanrix® hexa will be administered to all subjects at the discretion of the investigator.

One complimentary dose of Rotarix will be administered to all infants enrolled in this study (both study groups) who are aged less than 6 months at Visit 3 (Week 13) as a benefit to the placebo group for participation in the study.

The study will be conducted in a double-blind manner with respect to Rotarix and placebo administered at Visit 1 and Visit 2. The parents/guardians of the subjects will know that within each pair of twins, one subject will receive the Rotarix vaccine and one subject will receive the placebo.

The study will be open label with respect to administration of the Rotarix vaccine dose given at Visit 3 to all subjects in each group who are aged less than 6 months.
