OBJECTIVE: To evaluate whether there was a change in prevalence of human papillomavirus (HPV) in the United States correlated with the introduction of HPV vaccines in both vaccinated and unvaccinated women.
METHODS: We performed a retrospective review of prevalence data for women aged 18-29 years living in the United States using the National Health and Nutrition Examination Surveys, which is an ongoing series of cross-sectional surveys. Participants provided responses to standardized questions and self-collected cervicovaginal swabs in which a Linear Array HPV Assay was used to determine HPV prevalence. A total of 783 women from the prevaccine era (2003-2004) and 1,526 from the postvaccine era (2007-2012) were analyzed.
RESULTS: Among women aged 18-29 years, the prevalence of vaccine-type HPV declined among women receiving one or more doses of vaccine (P=.003): 10.1% (95% confidence interval [CI] 7.1-13.8%) in the prevaccine era to 4.2% (95% CI 3.3-10.9%) in the postvaccine era. There was no change in prevalence of nonvaccine-type HPV among women receiving one or more doses of vaccine (P>.05). There was also no change in prevalence of vaccine-type HPV among unvaccinated women from the prevaccine era 10.1% (95% CI 7.1-13.8%) to 8.8% (95% CI 5.6-12.9%) in the postvaccine era (P=.4). Vaccine coverage increased to 31.5% of eligible women aged 18-29 years as of 2011-2012.
CONCLUSION: Six years after introduction of HPV vaccination in the United States, there has been a decrease in the prevalence of vaccine-type HPV among women correlated with receiving one or more vaccine doses with no change in nonvaccine-type HPV. Furthermore, there has been no change in prevalence of vaccine-type HPV among unvaccinated women.
