监管机构最近紧急授权和推出COVID-19疫苗引起了全球关注。作为全球最受欢迎的视频分享平台，YouTube是传播重要公共卫生信息的有力媒介。了解这个广泛使用的平台上有关COVID-19疫苗接种的可用内容的性质具有重大的公共卫生利益。这项研究旨在评估YouTube视频中有关COVID-19疫苗接种信息的可靠性和质量。在这项横断面研究中，于2020年12月10日在英国版YouTube上搜索了“冠状病毒疫苗”和“COVID-19疫苗”这两个短语。每次搜索的200个观看次数最多的视频被提取并筛选相关性和英语。视频内容和特征被提取出来，并由2位作者根据网络健康基金会行为准则和DISCERN消费者健康信息质量标准进行独立评级。分析中包含了48个视频，总观看次数为30，100，561次。讨论的主题包括：疫苗科学（n=18，58%），疫苗试验（n=28，58%），副作用（n=23，48%），疗效（n=17，35%）和生产（n=8，17%）。10个（21%）视频鼓励继续采取公共卫生措施。只有2个（4.2%）视频提出了非事实性主张。47个（98%）视频的内容被评分为低（n=27，56%）或中等（n=20，42%）遵守网络健康基金会行为准则原则。每种通道类型的中位总体DISCERN评分范围为40.3（IQR 34.8-47.0）至64.3（IQR 58.5-66.3）。由医学和非医学专业人员制作的教育频道的DISCERN得分显著高于其他类别。由医疗专业人员制作的教育视频获得的DISCERN评分中位数最高（64.3，IQR 58.5-66.3），独立用户的评分中位数最低（18，IQR 18-20）。YouTube上关于COVID-19疫苗的信息的整体质量和可靠性仍然很差。教育渠道制作的视频，特别是医疗专业人员制作的视频，在质量和可靠性方面高于包括卫生相关组织在内的其他来源制作的视频。卫生相关组织与YouTube上知名的医疗和教育内容制作者之间的合作为传播有关COVID-19疫苗接种的高质量信息提供了机会。这种合作有可能成为一种可迅速实施的公共卫生干预措施，旨在吸引广泛的受众并提高公众对疫苗接种的认识和知识。
Recent emergency authorization and rollout of COVID-19 vaccines by regulatory bodies has generated global attention. As the most popular video-sharing platform globally, YouTube is a potent medium for the dissemination of key public health information. Understanding the nature of available content regarding COVID-19 vaccination on this widely used platform is of substantial public health interest. This study aimed to evaluate the reliability and quality of information on COVID-19 vaccination in YouTube videos. In this cross-sectional study, the phrases “coronavirus vaccine” and “COVID-19 vaccine” were searched on the UK version of YouTube on December 10, 2020. The 200 most viewed videos of each search were extracted and screened for relevance and English language. Video content and characteristics were extracted and independently rated against Health on the Net Foundation Code of Conduct and DISCERN quality criteria for consumer health information by 2 authors. Forty-eight videos, with a combined total view count of 30,100,561, were included in the analysis. Topics addressed comprised the following: vaccine science (n=18, 58%), vaccine trials (n=28, 58%), side effects (n=23, 48%), efficacy (n=17, 35%), and manufacturing (n=8, 17%). Ten (21%) videos encouraged continued public health measures. Only 2 (4.2%) videos made nonfactual claims. The content of 47 (98%) videos was scored to have low (n=27, 56%) or moderate (n=20, 42%) adherence to Health on the Net Foundation Code of Conduct principles. Median overall DISCERN score per channel type ranged from 40.3 (IQR 34.8-47.0) to 64.3 (IQR 58.5-66.3). Educational channels produced by both medical and nonmedical professionals achieved significantly higher DISCERN scores than those of other categories. The highest median DISCERN scores were achieved by educational videos produced by medical professionals (64.3, IQR 58.5-66.3) and the lowest median scores by independent users (18, IQR 18-20). The overall quality and reliability of information on COVID-19 vaccines on YouTube remains poor. Videos produced by educational channels, especially by medical professionals, were higher in quality and reliability than those produced by other sources, including health-related organizations. Collaboration between health-related organizations and established medical and educational YouTube content producers provides an opportunity for the dissemination of high-quality information on COVID-19 vaccination. Such collaboration holds potential as a rapidly implementable public health intervention aiming to engage a wide audience and increase public vaccination awareness and knowledge.
