151. Using Medical Claims Data to Explore Missed Opportunities for HPV Vaccination Among Adolescents, Ages 11-13, in Iowa

Abstract

Despite decades of safety and effectiveness data, human papillomavirus (HPV) vaccination rates remain low, and one-third of adolescents fail to initiate the series by age 13, the age at which it should be completed. While there is extensive research on factors related to uptake, there is less known about the times that eligible adolescents do not get vaccinated (missed opportunities [MOs]). This study sought to quantify the extent of MOs among adolescents ages 11 to 13 during both preventive and acute care visits.
