During the Covid-19 pandemic, risk communication has often been ineffective, and from this perspective “fake news” has found fertile ground, both as a cause and a consequence of it. The aim of this study is to measure how much “fake news” and corresponding verified news have circulated in Italy in the period between 31 December 2019 and 30 April 2020, and to estimate the quality of informal and formal communication. We used the BuzzSumo application to gather the most shared links on the Internet related to the pandemic in Italy, using keywords chosen according to the most frequent “fake news” during that period. For each research we noted the numbers of “fake news” articles and science-based news articles, as well as the number of engagements. We reviewed 2102 articles. Links that contained fake news were shared 2,352,585 times, accounting for 23.1% of the total shares of all the articles reviewed. Our study throws light on the “fake news” phenomenon in the SARS-CoV-2 pandemic. A quantitative assessment is fundamental in order to understand the impact of false information and to define political and technical interventions in health communication. Starting from this evaluation, health literacy should be improved by means of specific interventions in order to improve informal and formal communication.

Objectives: The Human papillomavirus (HPV) vaccine is a cornerstone of cancer prevention, yet uptake remains suboptimal in many countries. This study analyzed the factors influencing HPV vaccine acceptance among adults, including a focused analysis of parental behaviors. Methods: Data were collected through a web-based survey using a questionnaire. We performed univariable analysis and three logistic regression analyses to investigate the determinants in the overall sample and among parents. Results: A total of 1821 participants were surveyed. HPV vaccination uptake was low, with only 6.9% of the total sample and 7.6% of young adults (18–35 yo) vaccinated. Among parents, 47.9% had vaccinated children aged 12–17, and 21.1% those aged 18 and over. Higher health literacy was associated with positive attitudes (OR 2.03, 95% CI 1.48–2.79), while receiving information from pediatricians or gynecologists was linked to children’s vaccination status (OR 7.30, 95% CI 2.29–23.31) and parents’ intentions for future HPV vaccination (OR 5.86, 95% CI 1.85–18.50). Adequate knowledge emerged as a strong predictor of positive attitudes (OR 6.50, 95% CI 4.91–8.61) and parents’ intentions (OR 4.89, 95% CI 2.21–10.84). Vaccination status was a key factor influencing parental decisions and overall vaccine acceptance. Conclusions: These findings highlight the critical role of health professionals and the need for targeted communication to address persistent knowledge gaps and promote HPV vaccine confidence within general population.
