Summary:

      Infection with human papillomavirus (HPV) has been clearly established as the central cause
      of cervical cancer. This Phase IV, observer-blind study is designed to evaluate the safety
      and immunogenicity of Cervarix in HIV infected females aged 15 to 25 years as compared to
      Merck's HPV vaccine (Gardasil). For comparative purposes, a group of HIV negative females
      will also be evaluated. All subjects will receive the HPV vaccine (either Cervarix or
      Gardasil) according to a three-dose schedule (Day 0, Week 6, Month 6).
