Summary:

      This is a multicenter study in which women are planned to receive either the HPV vaccine or
      control. Study participation will last approximately 72 months and involves a total of
      thirteen or fourteen scheduled visits.

      Originally, the study was planned for 24 months. It was then extended for 2 more years with 4
      additional visits (study end at Month 48).

      The protocol posting has been updated as the study was extended by additional 2 years with
      two or three additional visits (study end at Month 72) for subjects who consent to
      participate in the extension.
