This study will evaluate the effectiveness of two communication trainings to increase HPV vaccination coverage among adolescent patients. We will compare HPV vaccination for pediatric and family medicine clinics receiving a participatory communication training, efficient communication training, or no training. Ten clinics will be randomly assigned to each study arm for a total of 30 clinics. The primary outcome of this study is to compare the change in clinics' levels of HPV vaccination initiation coverage among 11-12 year old adolescent patients from baseline to 6 month follow-up. Secondarily, we will compare the change in HPV vaccination initiation coverage in 13-17 year old adolescents.
