Vaccine To Prevent Cervical Intraepithelial Neoplasia or Cervical Cancer in Younger Healthy Participants
A Double-Blind, Controlled, Randomized, Phase III Study of the Efficacy of an HPV16/18 VLP Vaccine in the Prevention of Advanced Cervical Intraepithelial Neoplasia (CIN2, CIN3, Adenocarcinoma In Situ [AIS] and Invasive Cervical Cancer) Associated With HPV 16 or HPV 18 Cervical Infection in Healthy Young Adult Women in Costa Rica.

Summary
Brief summary (as posted)
RATIONALE: Chemoprevention is the use of certain drugs to keep cancer form forming, growing, or coming back. Vaccines may help the body build an effective immune response against human papillomavirus and may be effective in preventing cervical intraepithelial neoplasia or cervical cancer. It is not yet known whether human papillomavirus vaccine is more effective than hepatitis A vaccine in preventing cervical intraepithelial neoplasia or cervical cancer. PURPOSE: This randomized phase III trial is studying human papillomavirus vaccine to see how well it works compared to hepatitis A vaccine in preventing cervical intraepithelial neoplasia or cervical cancer in younger healthy participants.
