Brief Summary
Cutaneous viral warts are very common and are caused by the human papilloma virus (HPV). Most people experience warts in one form or another at some point in their lives. Cutaneous warts are related to different types of HPV. For the palms and soles, HPV 2 has been the most frequently found but HPV 1, 4, 27, and 57 have also been described. Our hypothesis is that vaccination by nonavalent vaccine against HPV could lead to a complete resolution of difficult-to-treat palmo-plantar warts patients of more than 15 years and 3 months of age.

- Double blind clinical trial.The identity of Gardasil 9® vaccine and placebo cannot be concealed as presentation. They will be packed in boxes of identical appearance to achieve double blindness. During the study designated unblinded trained and qualified site staff will be responsible for preparing the Gardasil 9® vaccine or placebo out of view of patients and an unblinded nurse(s) or physician(s) will be responsible for administering the study products to the patients.
