用网络舆情监测增强疫苗安全监控，发现公众疑虑并针对性应对。
VaxPulse: Monitoring of Online Public Concerns to Enhance Post-licensure Vaccine Surveillance
- 构建多步骤框架VaxPulse，融合疫苗不良反应与在线情绪分析。
- 识别出女性群体中显著的疫苗犹豫现象，支持精准干预策略。
- 涵盖非英语语种，助力跨语言社群的疫苗认知差异研究。
近期疫苗相关虚假信息泛滥，加剧了公众担忧，凸显主动管理谣言的必要性。本文介绍如何通过引入网络舆论分析、话题讨论及疫苗犹豫信号等新信息源，提升维多利亚州疫苗安全服务（SAEFVIC）的报告监测系统。基于VaxPulse多步骤框架，将免疫后不良事件（AEFI）与情感分析结合，强调在上下文中理解公众关切的重要性。同时指出需关注非英语语言，以分层分析不同族裔语言群体的担忧，为提升疫苗接种率和打击虚假信息提供关键洞察。该框架应用于真实案例与女性疫苗犹豫专题研究，成功从在线媒体中提取公众意见，展现其有效性与可扩展性。
原文摘要 · Abstract (English)
The recent vaccine-related infodemic has amplified public concerns, highlighting the need for proactive misinformation management. We describe how we enhanced the reporting surveillance system of Victoria's vaccine safety service, SAEFVIC, through the incorporation of new information sources for public sentiment analysis, topics of discussion, and hesitancies about vaccinations online. Using VaxPulse, a multi-step framework, we integrate adverse events following immunisation (AEFI) with sentiment analysis, demonstrating the importance of contextualising public concerns. Additionally, we emphasise the need to address non-English languages to stratify concerns across ethno-lingual communities, providing valuable insights for vaccine uptake strategies and combating mis/disinformation. The framework is applied to real-world examples and a case study on women's vaccine hesitancy, showcasing its benefits and adaptability by identifying public opinion from online media.
