Villa and colleagues randomized 277 young women (mean age, 20.2 1.7 years) to receive quadrivalent HPV vaccine, and 275 women (mean age, 20.0 1.7 years) were randomized to receive one of two placebo preparations at day 1, month 2, and month 6. Participants had regular gynecological examinations, cervicovaginal sampling for HPV DNA, testing for serum antibodies to HPV, and Papanicolaou testing for 36 months.
