In Brief In a large health insurance database in Germany, incidence of anogenital warts among 15- to 19-year-old females decreased from 316/100,000 person-years in 2007 to 242 in 2008 (23% reduction, P = 0.0001). The decrease started between the first and second quarter of 2007 (human papillomavirus vaccination was introduced in March 2007). This study, based on health insurance data, demonstrated changes in the incidence of anogenital warts after the introduction of human papillomavirus vaccination for the first time in Germany.
