About the National Data
Data
Baseline: 15.1 percent of persons aged 20 to 34 years were positive for at least 1 HPV type prevented by the 9-valent vaccine in 2013-16
Target: 8.7 percent
Methodology
Methodology notes
HPV infection is determined through laboratory testing of specimens collected from NHANES participants. Prevalence of the 9 HPV types prevented by the vaccine will be compared to prevalence in previous years.
HPV data is unavailable for 2017-2020 as HPV was not included in the survey after 2018 due to the COVID-19 pandemic. CDC plans to include HPV questions in the survey beginning in 2025.
