Rotavirus is the most common cause of severe diarrhea among children worldwide. In 2017, Italy included rotavirus vaccination in its National Immunization Program. The use of social media monitoring, an efficient tool to understand vaccine hesitancy, has increased in recent years; however, only a few examples of such monitoring are available for Italy. Present study analyzed content on online sources, including social media, to identify factors contributing to Italian parents' decisions to vaccinate or not their children against rotavirus. Blogmeter Suite was used to search and analyze conversations related to rotavirus in Italian on online sources during 2020. These data were compared with data from 2019. There were 2250 mentions of "rotavirus" recorded; 1080 were related to the rotavirus vaccine. Terms and hashtags used were similar in both years. Facebook was the main source of influence, Instagram dominated the engagement (the sum of interactions related to a post), and Google Trends showed a 5-year upward trend in searches for rotavirus vaccine. Of 1270 sentiment opinions, 60.7% were negative. More parents were familiar with the disease and the vaccine in 2020 compared with 2019. Pediatricians were the most influential healthcare professionals (59.2% of mentions), followed by vaccination staff (33.4%). The most relevant factors for vaccine hesitancy were fear of adverse events, concerns about the vaccination schedule, and COVID-19. Present study represents the first web listening analysis of online discussions about rotavirus. The results can be used to inform targeted communication to counteract misinformation and raise awareness about rotavirus vaccination among parents.
轮状病毒是全球儿童严重腹泻的最常见原因。2017 年，意大利将轮状病毒疫苗接种纳入国家免疫计划。近年来，利用社交媒体监测这一了解疫苗犹豫的有效工具的使用有所增加；然而，意大利仅有少数此类监测的例子。本研究分析了在线来源（包括社交媒体）上的内容，以确定导致意大利父母决定为其子女接种或不接种轮状病毒疫苗的因素。使用 Blogmeter Suite 搜索和分析 2020 年意大利在线来源中与轮状病毒相关的对话。将这些数据与 2019 年的数据进行比较。共记录了 2250 次“轮状病毒”的提及；其中 1080 次与轮状病毒疫苗有关。这两年使用的术语和标签相似。Facebook 是主要的影响来源，Instagram 主导着互动（与帖子相关的互动总和），Google Trends 显示轮状病毒疫苗搜索量在过去 5 年呈上升趋势。在 1270 条意见中，有 60.7%是负面的。与 2019 年相比，2020 年更多的父母对这种疾病和疫苗有所了解。儿科医生是最有影响力的医疗保健专业人员（提及的 59.2%），其次是疫苗接种人员（33.4%）。疫苗犹豫的最相关因素是对不良事件的恐惧、对接种时间表的担忧以及 COVID-19。本研究代表了对轮状病毒在线讨论的首次网络听力分析。研究结果可用于提供有针对性的沟通，以对抗错误信息，并提高父母对轮状病毒疫苗接种的认识。
