The VIVA Trial

The VIVA Clinical Trial (Vaccine to Interrupt Progression of Vulvar and Anal Neoplasia) will test whether the Human Papillomavirus (HPV) vaccine can improve the health of people who have been previously diagnosed with pre-cancerous lesions.

We plan to enroll men and women in the Seattle area with a history of pre-cancerous lesions, who will be randomly assigned to receive either the Gardasil vaccine or a saline solution (placebo) vaccine.  Participants will be asked to come to the clinic for a total of 7 visits over 3 years.  All participants will receive a total of 3 injections in the arm (Enrollment, Month 2, and Month 6) and will complete questionnaires, and have physical exams, blood draws and biopsies at the pre-cancerous lesion site.


Participant Eligibility

  • Between the ages of 27- 69 at the time of diagnosis of pre-cancerous lesions
