Awareness of Virus–Cancer Links and Willingness to Vaccinate Against a Cancer-Associated Virus by HPV Vaccination Status Among Polish Students: A Cross-Sectional Study

Background/Objectives: Prevention of virus-related cancers is a multifaceted process shaped by vaccination and public awareness. This study assessed awareness of virus–cancer relationships and willingness to vaccinate against a cancer-associated virus among medical and non-medical students. We also evaluated whether human papillomavirus (HPV)-vaccinated students demonstrate greater awareness of the HPV-cancer link compared to unvaccinated students, and examined willingness to vaccinate against a certain cancer-associated virus according to HPV vaccination status. Methods: This cross-sectional survey was conducted in Poland (October 2023–June 2024) and included 1013 first- and second-year university students recruited via convenience sampling. Participation was voluntary and anonymous. Results: Awareness of virus–cancer relationships was low, ranging from 19% for Epstein–Barr virus-related cancers to 43.8% for HPV-related cervical cancer. Women were more likely than men to recognize the HPV–cervical cancer link (OR = 2.08, p < 0.001), supporting gender differences and the need for gender-neutral HPV education with targeted strategies for men. Medical students demonstrated higher awareness than non-medical students. HPV vaccination coverage was low (14.5%), with higher uptake among medical students (21.2% vs. 8.2%). Notably, 41.3% of non-medical students and 7.5% of medical students had never heard of HPV vaccination. Willingness to vaccinate against a cancer-associated virus varied according to perceived infection risk. Conclusions: These findings highlight the need for targeted educational interventions to improve awareness of HPV–cancer links and risk perception, as well as to ensure ongoing education of both HPV-vaccinated and unvaccinated individuals to support informed health decisions and vaccine acceptance.
