Characteristics of Human Papillomavirus (HPV) Infections and HPV Vaccine Attitudes Among Slovenian Women After the Introduction of HPV Vaccination

Rövid összefoglaló (regiszter, angolul)

Cervical cancer (CC), primarily caused by persistent infection with high-risk human papillomavirus (HPV) types, remains a significant public health issue. Despite the availability of prophylactic HPV vaccines and improved screening methods, vaccination coverage and uptake remain suboptimal in many countries, including Slovenia. In 2020, the WHO launched a global strategy to eliminate CC, emphasizing 90% HPV vaccination coverage among girls, 70% screening of women at key ages, and 90% treatment of identified cases by 2030. The EVEN FASTER concept proposes that targeting a specific age group of women-those bridging unvaccinated and vaccinated cohorts-with simultaneous HPV screening and vaccination may significantly reduce HPV transmission. Swedish data support this, showing a 62-64% reduction in high-risk HPV infections following combined interventions in women aged 23-30. In Slovenia, HPV vaccination has been available since 2006 for girls, and since 2021 for boys, with average uptake around 50%. However, no comparable model has been implemented or studied locally. This proposed clinical study will assess HPV vaccine acceptability among women in Slovenia, identify barriers to uptake, define an optimal target age group for intervention, and evaluate the effectiveness of offering concurrent screening and vaccination to accelerate CC prevention in this region. Women will be invited to participate during their preventive gynecological examination within Slovenia's national cervical cancer screening program (ZORA). Inclusion criteria include regular cervical smears (CS) every 3 years following a previously normal result, first or second CS after entering the ZORA program, follow-up CS after abnormal cytology, non-neoplastic findings, or cervical procedures, and CS due to clinical indications. Exclusion criteria include pregnancy, menstruation, cervical or vaginal inflammation, other medical conditions preventing CS collection, prior hysterectomy, prior CS taken for this study, or known hypersensitivity to HPV vaccine components. Eligible women will be invited by the attending gynecologist and nurse. After the exam, participants will complete an anonymous questionnaire covering demographics, screening history, vaccination status, and vaccine attitudes. Assistance will be provided if needed. Women aged ≤35 who are unvaccinated will receive counseling on HPV vaccination, including benefits and risks. Those consenting will receive free vaccination with the nonavalent Gardasil®9 vaccine, following a three-dose schedule (0, 1-2, 6 months). Around 500 women aged ≤35 are expected in this sub-group, with fewer than half anticipated to accept vaccination. Data will be anonymized and analyzed using SPSS (p < 0.05).
