HPV vaccination coverage and willingness to be vaccinated among 18-30 year-old students in Italy

Objectives: In Italy, free HPV vaccination has been offered to 12 years-old girls since 2007, while for males only since 2015. The aims of our study were: to measure HPV vaccination coverage among young women; to assess willingness to receive HPV vaccination among unvaccinated males and females; to evaluate the association of coverage and attitudes with knowledge regarding HPV and with sexual behavior. Methods: A cross-sectional survey was conducted in an Italian region among 18-30 year-old students attending medical and healthcare professions schools. Participants completed a self-administered questionnaire exploring knowledge, attitudes and behaviors related to HPV infections, sexually transmitted diseases and their prevention. Information on vaccination status was also verified for each student through the immunization records provided by the participants during the occupational medical visit. Results: 517 students were enrolled, with a 97% response rate. Of female participants, 40.5% had received at least one dose of HPV vaccine, while among unvaccinated participants, 60.5% stated their willingness to be vaccinated. A negative attitude towards HPV vaccination was associated with an older age, whereas a correct knowledge that both sexes are at risk of HPV infection, and the knowledge that vaccine protects against cervical cancer were confirmed to be associated to a willingness to receive HPV vaccination. Conclusions: Our results showed low HPV vaccination coverage among young women and high reported willingness to receive vaccination among both sexes. More active education on the link between HPV and all related cancers could be beneficial to help prevent significant burden of the HPV-related diseases. (C) 2019 Published by Elsevier Ltd.
