Young women aged 20 to 29 years who were screened for cervical cancer saw reduction in vaccine-type (VT) human papillomavirus (HPV) within 6 years of the vaccine introduction, according to a study of 4,181 women in an integrated healthcare delivery system. The study compared HPV prevalence in 2007 and 2012-13 and evaluated predictors of VT HPV and any-HPV prevalence in 2012-13. Study findings revealed:
• 31.9% of the study group had initiated HPV vaccination.
• VT HPV prevalence decreased from 10.6% in 2007 to 6.2% in 2012-13.
• VT HPV prevalence was significantly lower among individuals who initiated vaccination than among those who were not vaccinated.
