YouTube has become a large source of health information, and it has the capacity to influence users: for instance, regarding their vaccination habits. The aim of our study was to analyze the characteristics of the videos published on YouTube about the meningococcal B vaccine (4CMenB, Bexsero®). A search was made on YouTube using the keyword "Bexsero." The association between the authorship of videos (health professionals or others) and the rest of the variables (tone of the message and vaccination recommendations, among others) was evaluated using the Chi-square test. In total, 77 videos were analyzed; 74% supported the use of the vaccine, and the most frequently mentioned vaccination recommendations were in epidemic outbreaks (28.6%) and in children (18.2%). Depending on the type of authorship, significant differences were observed regarding the tone of the message and the frequency with which the videos discussed effectiveness, dosage, adverse effects, and vaccination recommendations. There is a difficulty in obtaining information on vaccination recommendations. Recommendations are very diverse since there is a great heterogeneity in the official recommendations for the use of this vaccine, depending on the country the information is from.
YouTube 已成为获取健康信息的重要来源，其具有影响用户的能力：例如，影响其疫苗接种习惯。我们研究的目的是分析关于脑膜炎球菌 B 疫苗（4CMenB，Bexsero®）的 YouTube 上发布的视频的特点。使用关键词“Bexsero”在 YouTube 上进行了搜索。使用卡方检验评估了视频作者（健康专业人员或其他人员）与其他变量（信息基调以及疫苗接种建议等）之间的关联。共分析了 77 个视频；74%的视频支持使用疫苗，最常提到的疫苗接种建议是在流行爆发时（28.6%）和儿童中（18.2%）。根据作者类型，信息基调以及讨论有效性、剂量、不良反应和疫苗接种建议的视频频率存在显著差异。获取疫苗接种建议的信息存在困难。由于来自不同国家的官方对该疫苗使用的建议存在很大差异，因此建议也非常多样化。
