目标：提高对导致医护人员 (HCP) 不愿接种季节性流感疫苗的机制的了解。我们评估了几个驱动因素的作用：疫苗接种知识、疫苗接种建议以及互联网（所谓的电子健康）在创造疫苗接种知识中的作用。所考虑的关键机制是感知的自身风险（关于疾病和疫苗）。方法：法兰克福大学医院的 310 名医学生回答了一份匿名调查问卷，评估风险认知、接种疫苗的意愿、知识、个人健康决策信息源的偏好以及他们在谷歌搜索中用于季节性流感疫苗接种的搜索词。结果：疫苗接种意愿的关键驱动因素是感知的自身风险（感染流感和遭受疫苗不良事件）。接种疫苗的建议是一个重要但较弱的预测因素。作为间接驱动因素，我们确定了一个人有关疫苗接种的知识。 32%的知识问题回答错误或不知道。 64%的学生是电子医疗用户；因此，通过互联网搜索额外的信息是可能的。对学生提供的搜索词进行谷歌分析后发现，30% 是商业电子健康网站，11% 是反疫苗网站，10% 是公共卫生网站。与没有风险作为搜索词的搜索相比，明确搜索疫苗接种风险导致的公共卫生网站数量较少。对前三个网站的内容分析显示，关于疫苗添加剂的剂量是否危险、疫苗是否引发慢性疾病以及疫苗是否促进过敏等问题，正确信息分别占58%、53%和34%。这些问题尤其与自身风险相关，这强烈预测了意图。 85% 的网站提供了有关疫苗接种建议的正确信息。结论：专注于早期医学教育的关键驱动因素（感染流感的自身风险、疫苗安全性、疫苗接种建议）有望成为提高 HCP 疫苗接种率的成功组合。 (C) 2011 Elsevier Ltd. 保留所有权利。
Objective: was to improve understanding of mechanisms contributing to healthcare personnel's (HCP) reluctance to get vaccinated against seasonal influenza. We assessed the role of several drivers: vaccination knowledge, vaccination recommendations and the role of the Internet (so-called e-health) in creating vaccination knowledge. The key mechanism under consideration was the perceived own risk (regarding disease and the vaccine).Method: 310 medical students at the Frankfurt University Hospital answered an anonymous questionnaire assessing risk perceptions, intentions to get vaccinated, knowledge, preferences regarding information sources for personal health decisions and search-terms that they would use in a Google-search directed at seasonal influenza vaccination.Results: The key driver of vaccination intentions was the perceived own risk (of contracting influenza and of suffering from vaccine adverse events). The recommendation to get vaccinated was a significant, yet weaker predictor. As an indirect driver we identified one's knowledge concerning vaccination. 32% of the knowledge questions were answered incorrectly or as don't know. 64% of the students were e-health users; therefore, additional information search via the Internet was likely. An analysis of the websites obtained by googling the search-terms provided by the students revealed 30% commercial e-health websites, 11% anti-vaccination websites and 10% public health websites. Explicit searches for vaccination risks led to fewer public health websites than searches without risk as a search term. Content analysis of the first three websites obtained revealed correct information regarding the questions of whether the doses of vaccine additives were dangerous, whether chronic diseases are triggered by vaccines and whether vaccines promote allergies in 58%, 53% and 34% of the websites, respectively. These questions were especially related to own risk, which strongly predicted intentions. Correct information on vaccination recommendations were provided on 85% of the websites.Conclusion: Concentrating on the key drivers in early medical education (own risk of contracting influenza, vaccine safety, vaccination recommendation) promises to be a successful combination to increase vaccination uptake in HCP.
