Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Between October 11, 2006 and November 22, 2006 130 participants were enrolled at 34 clinical sites from US & Puerto Rico.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Participants were stratified by CD4% criteria. Four participants were randomized but did not receive the study treatment. The study analyses were based on 126 participants who received the study treatment.

Reporting Groups
  Description
Arm A QHPV Participants received three doses of the quadrivalent human papillomavirus vaccine (QHPV) (Types 6, 11, 16, 18) at week 0, 8, and 24 and an additional dose at week 96.
Arm B Placebo/QHPV Participants received three doses of the placebo at week 0, 8, and 24 and additional dose of the quadrivalent human papillomavirus vaccine (QHPV) (Types 6, 11, 16, 18) at week 96, 104 and 120.
