研究概览
简要总结
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).
