Patients who carry the diagnosis of Recurrent Respiratory Papillomatosis (RRP) will be asked to participate in the study. These patients have been followed by the faculty investigator for several years. Their disease state requires frequent interventions aimed at decreasing the severity and symptomatology of their vocal fold papillomas. Patients will be given the human papillomavirus quadrivalent vaccine and their clinical course will be followed over the next 6 months. Patients will have a laryngoscopic examination prior to treatment to establish their baseline disease state. They will have repeat laryngoscopic examinations at the time of the first, second and third vaccine injections, which will be given 1 month intervals for a total of 3 doses. They will have physical exam and laryngoscopic examinations at 1 month intervals for the first 6 months after administration of the vaccine. The severity of their clinical disease will be objectively measured using a validated scale for RRP assessment, the Laryngoscopic and Clinical Assessment Scale (LCAS).
