Official Title: Investigator Initiated Study of Effects of Progression of Recurrent Respiratory Papillomatosis in Patients After They Are Given Human Papillomavirus Quadrivalent Vaccine

Brief Summary: The purpose of this study is to determine if administration of the HPV quadrivalent vaccine in patients diagnosed with RRP has a therapeutic effect on their clinical course. More specifically, does administration of the vaccine decrease the size and number of papillomas, severity of disease (i.e. hoarseness, inspiratory vs. biphasic stridor, airway obstruction) using the LCAS and time interval between required surgical debulking will be analyzed.

Detailed Summary: 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).

Current Primary Outcome: Comparison of the pre-vaccine and post-vaccine RRP scoring assessments, intersurgical intervals, and annualized surgical rates. [ Time Frame: 12 months ]

Original Primary Outcome: Same as current

Current Secondary Outcome: The secondary end points will include changes in the RRP scoring assessment, intersurgical intervals and changes in annualized surgical rates. [ Time Frame: 12 months ]

Original Secondary Outcome: Same as current
