Study to Assess Immune Responses and Safety of the GSK-580299 Vaccine in Healthy Women (26 to 45 Years)

Immunogenicity and Safety Study of GSK Biologicals' HPV Vaccine (GSK 580299) in Healthy Adult Chinese Female Subjects

This study is designed to evaluate the immunogenicity and safety of GSK Biologicals' human papillomavirus (HPV) vaccine in adult female subjects aged 26-45 years. One group of subjects will receive the HPV vaccine and the other group will receive an active control (GSK Biologicals' hepatitis B vaccine). Immunogenicity data of the HPV group will be compared with those from the HPV group included in the NCT00779766 study (aged 18-25 years).
