Dataset from Immunogenicity and Safety of the Diphtheria, Tetanus, Pertussis and Inactivated Poliovirus (DPT-IPV) Vaccine Squarekids Co-administered With GSK Biologicals' Human Rotavirus (HRV) Vaccine Rotarix (GSK444563) in Healthy Infants

The purpose of this study is to evaluate the immunogenicity and safety of the diphtheria, tetanus, pertussis and inactivated poliovirus (DPT-IPV) vaccine Squarekids administered with or without the GSK Biologicals' liquid Rotarix (HRV) vaccine, in healthy Japanese infants aged 6 - 12 weeks. GSK Biologicals' liquid HRV vaccine Rotarix is licensed in Japan since 2011. Although the concomitant administration of GSK Biologicals' DTP-IPV vaccine has been evaluated during the clinical development of the HRV vaccine, the vaccine differed in composition and route of administration from the DPT-IPV vaccine Squarekids manufactured in Japan. Hence, as requested by the Japanese regulatory authorities, this post-licensure study will evaluate the immunogenicity of the DPT-IPV vaccine manufactured in Japan when co-administered with the liquid HRV vaccine
