Overview
- The cross-sectional JAMA Oncology analysis of 22,344 HINTS respondents found that 34.3% of U.S. adults had never heard of HPV and 37.6% were unaware of its vaccine.
- Among adults who knew of HPV, 70.8% did not recognize its link to oral cancer, and 28.3% were unaware of its connection to cervical cancer.
- Awareness gaps were most pronounced in Midwestern and Southern states, where more than 40% of adults lacked knowledge of HPV in seven states and of the vaccine in 13 states.
- In 45 states and the District of Columbia, over 60% of those aware of HPV did not know it could cause oral cancer, underscoring uneven public understanding of the virus’s broader risks.
- Study authors and public-health experts warn that targeted education, provider engagement and catch-up immunization efforts are needed to translate decades of vaccine efficacy into equitable cancer prevention.
