Brief Summary: This study is planned to evaluate the safety (in terms of occurrence of any serious adverse events), reactogenicity (any side effects) and immunogenicity (ability of the vaccine to develop antibodies that fight infection) of the HRV vaccine when used in pre-term infants aged between 6 and 14 weeks at the time of the first dose in Portugal, France and Poland and in pre-term infants aged between 6 and 12 weeks at the time of first dose in Spain. The study will be performed in four European countries (France, Poland, Spain, and Portugal). The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
