Our objective was to analyze the information in Spanish on YouTube about the influenza vaccine. In August 2020, a search was conducted on YouTube using the terms "Vacuna gripe", "Vacuna influenza", and "Vacuna gripa". Associations between the type of authorship, country of publication, and other variables (such as tone, hoaxes, and vaccination recommendations) were studied via univariate analysis. A total of 100 videos were evaluated; 57.0% were created in Mexico (24.0%), Argentina (17.0%), and Spain (16.0%), and 74.0% were produced by mass media or health professionals. Positive messages were detected in 65.0%. The main topics were the benefits of the vaccine (59.0%) and adverse effects (39.0%). Hoaxes were detected in 19 videos. User-generated content, compared to that of health professionals, showed a higher probability of hoaxes (odds ratio (OR) = 15.56), a lower positive tone (OR = 0.04), and less evidence of recommendations to vaccinate pregnant individuals (OR = 0.09) and people aged 60/65 or older. Videos published in Spain, in comparison with those from Hispanic America, presented significant differences in the positive tone of their messages (OR = 0.19) and in the evidence of the benefits of vaccination (OR = 0.32). A higher probability of hoaxes was detected in videos from Spain and the USA. Information in Spanish about the influenza vaccine on YouTube is usually not very complete. Spanish health professionals are urged to produce pro-vaccination videos that counteract hoaxes, and users in Hispanic America should be advised to consult videos produced in Hispanic American countries by health professionals to obtain reliable information.
我们的目的是分析西班牙语关于流感疫苗的 YouTube 信息。2020 年 8 月，在 YouTube 上使用“Vacuna gripe”、“Vacuna influenza”和“Vacuna gripa”进行搜索。通过单变量分析研究了作者类型、出版国家和其他变量（如语气、骗局和疫苗接种建议）之间的关联。共评估了 100 个视频；57.0%来自墨西哥（24.0%）、阿根廷（17.0%）和西班牙（16.0%），74.0%由大众媒体或卫生专业人员制作。发现 65.0%的视频为正面信息。主要主题是疫苗的益处（59.0%）和不良反应（39.0%）。发现 19 个视频存在骗局。与卫生专业人员相比，用户生成的内容更有可能存在骗局（优势比（OR）=15.56），语气更消极（OR=0.04），推荐孕妇（OR=0.09）和 60/65 岁及以上人群接种疫苗的证据更少。与来自西班牙的视频相比，来自西班牙裔美洲的视频在信息语气（OR=0.19）和疫苗接种益处的证据（OR=0.32）方面存在显著差异。在西班牙和美国的视频中发现存在骗局的可能性更高。YouTube 上西班牙语关于流感疫苗的信息通常不够完整。敦促西班牙卫生专业人员制作宣传疫苗接种的视频，以对抗骗局，建议西班牙裔美洲的用户咨询由卫生专业人员在西班牙裔美洲国家制作的视频，以获取可靠信息。
