This exploratory study investigated the web accessibility of 54 official COVID-19 vaccine registration websites in the US and their concordance with the WCAG 2.0 and 2.1 guidelines. We employed AChecker, WAVE, and SortSite web accessibility evaluation tools to conduct automated analyses of these websites. The results showed suboptimal compliance with WCAG 2.0 and 2.1 guidelines, as determined using the AChecker, WAVE, and SortSite tools. These shortcomings in compliance may pose difficulties to users with disabilities as they access information on the websites. Based on our findings, we offered recommendations for states and other authorities to improve the accessibility of their websites to ensure that users with disabilities can independently schedule vaccination appointments.
这项探索性研究调查了美国54个官方新冠疫苗注册网站的网络可访问性，以及它们与《网络内容无障碍指南》2.0版和2.1版的一致性。我们使用AChecker、WAVE和SortSite网络可访问性评估工具对这些网站进行自动分析。结果显示，使用AChecker、WAVE和SortSite工具评估发现，这些网站对《网络内容无障碍指南》2.0版和2.1版的遵守情况欠佳。这些合规方面的不足可能会给残疾用户访问网站信息带来困难。基于我们的研究结果，我们为各州和其他当局提供了建议，以提高其网站的可访问性，确保残疾用户能够独立安排疫苗接种预约。
