Beliefs about HPV vaccination and awareness of vaccination status: Gender differences among Northern Italy adolescents

Acceptance, Knowledge, and Attitude of Parents Toward the Human Papillomavirus Vaccine in the Eastern Region of Saudi Arabia: A Cross-Sectional Study

Background Human papillomavirus (HPV) is a common sexually transmitted virus associated with conditions such as skin warts and cervical cancer. Although many individuals clear the infection, some face persistent risks. Cervical cancer, which is linked to certain types of HPV, is a major health concern both globally and in Saudi Arabia, with preventive measures including HPV vaccination. However, parental knowledge and attitudes toward vaccinating their children vary. Therefore, this research aims to assess parental acceptance and understanding of the HPV vaccine in the Eastern Region of Saudi Arabia. Methodology This cross-sectional study was conducted in the Eastern Region of Saudi Arabia using an online questionnaire during 2022-2023. The data were cleaned in Excel and analyzed using SPSS version 29 (IBM Corp., Armonk, NY, USA). The study assessed parents' knowledge and acceptance of HPV vaccination. Results A total of 380 participants were included in this study, the majority of whom were female, married, well-educated, and residents of Al-Ahsa, Saudi Arabia. Awareness about the HPV vaccine was modest, with only 46.6% of participants having heard of it. Most parents reported that their doctors did not mention the vaccine (62.9%), and 67.1% stated that their children had not received it. Factors influencing acceptance included support from the Ministry of Health and belief in the vaccine's effectiveness. Concerns about side effects and vaccine effectiveness were the main barriers to vaccination. Sociodemographic factors, including gender, age, education, employment, and number of children, significantly influenced both knowledge and acceptance. Notably, awareness of HPV was strongly associated with acceptance. Conclusions Our study revealed limited knowledge and vaccine acceptance among parents in the Eastern Region of Saudi Arabia. Sociodemographic factors, including gender, age, education, employment, and number of children, significantly influenced both knowledge and acceptance. Thus, sociodemographic factors played a significant role in shaping these attitudes, emphasizing the need for targeted awareness campaigns and improved communication between healthcare providers and parents to enhance vaccine uptake.

HPV Vaccination during the COVID-19 Pandemic in Italy: Opportunity Loss or Incremental Cost

Objectives: Italy was the first European country to introduce universal vaccination of adolescents, for both males and females, against Human Papilloma Virus (HPV) starting in 2017 with the NIP 2017–2019′s release. However, vaccine coverage rates (VCRs) among adolescents have shown a precarious take-off since the NIP’s release, and this situation worsened due to the impact of the COVID-19 pandemic in 2020. The aim of this work is to estimate the epidemiological and economic impact of drops in VCRs due to the pandemic on those generations that missed the vaccination appointment and to discuss alternative scenarios in light of the national data. Methods: Through an analysis of the official ministerial HPV vaccination reports, a model was developed to estimate the number of 12-year-old males and females who were not vaccinated against HPV during the period 2017–2021. Based on previously published models that estimate the incidence and the economic impact of HPV-related diseases in Italy, a new model was developed to estimate the impact of the aggregated HPV VCRs achieved in Italy between 2017 and 2021. Results: Overall, in 2021, 723,375 girls and 1,011,906 boys born between 2005 and 2009 were not vaccinated against HPV in Italy (42% and 52% of these cohorts, respectively). As compared with the 95% target provided by the Italian NIP, between 505,000 and 634,000 girls will not be protected against a large number of HPV-related diseases. For boys, the number of the unvaccinated population compared to the applicable target is over 615,000 in the ‘best case scenario’ and over 749,000 in the ‘worst case scenario’. Overall, between 1.1 and 1.3 million young adolescents born between 2005 and 2009 will not be protected against HPV-related diseases over their lifetime with expected lifetime costs of non-vaccination that will be over EUR 905 million. If the 95% optimal VCRs were achieved, the model estimates a cost reduction equal to EUR 529 million, the net of the costs incurred to implement the vaccination program. Conclusion: Suboptimal vaccination coverage represents a missed opportunity, not only because of the increased burden of HPV-related diseases, but also in terms of economic loss. Thus, reaching national HPV immunization goals is a public health priority.
