As the coronavirus disease 2019 (COVID-19) vaccine is introduced, it is critical to recognize that public opinion on vaccines is largely influenced by health communications, with YouTube being a major source of information and misinformation. This analysis graded the accuracy, quality, and reliability of the most viewed YouTube videos depicting COVID-19 and vaccinations over a 6-mo period.
We collected hyperlinks for the 150 most viewed YouTube videos discussing COVID-19 from January through June 2020. Closed captioning data were searched for the term "vaccine," yielding 32 videos. This sample was evaluated for quality, accuracy, and reliability using a rubric that incorporated existing instruments: Global Quality Scale (GQS), JAMA Benchmark Criteria, and DISCERN.
These 32 videos had 139,764,188 views at the time of data collection. The majority of videos received low scores, with network news sources receiving the lowest scores overall.
The overall quality of COVID-19 YouTube videos related to vaccines may be low and raises a precautionary alert for the public consuming these videos and for health-care providers working to provide the best information to their patients. Existing scoring tools may not capture the complexities of social media. New tools could allow for a better understanding of the modern landscape of health communications.
随着2019冠状病毒病（COVID-19）疫苗的推出，认识到公众对疫苗的看法在很大程度上受健康传播的影响至关重要，其中YouTube是信息和错误信息的主要来源。本分析对6个月期间观看次数最多的描绘COVID-19和疫苗接种的YouTube视频的准确性、质量和可靠性进行了分级。
我们收集了2020年1月至6月期间YouTube上150个观看次数最多的讨论COVID-19的视频的超链接。在隐藏式字幕数据中搜索“疫苗”一词，得到32个视频。使用包含现有工具的评分标准（全球质量量表（GQS）、《美国医学会杂志》基准标准和辨别力）对该样本的质量、准确性和可靠性进行评估。
在数据收集时，这32个视频的观看次数达到139,764,188次。大多数视频得分较低，其中网络新闻来源的总体得分最低。
与疫苗相关的COVID-19 YouTube视频的整体质量可能较低，这对观看这些视频的公众以及努力为患者提供最佳信息的医疗保健提供者发出了预防性警报。现有的评分工具可能无法捕捉社交媒体的复杂性。新的工具可以使人们更好地了解健康传播的现代格局。
