COVID-19疫情爆发至今已一年。好消息是，几家制造商开发的疫苗正在全球范围内积极分销。然而，随着越来越多的疫苗可供公众使用，与疫苗相关的各种担忧成为可能阻碍公众接种疫苗的主要障碍。考虑到这些问题的复杂性及其潜在危害，这项研究旨在清楚地了解不同人群在谈论COVID-19疫苗时的潜在担忧-特别是那些在Reddit上活跃的人群。这一目标是通过应用LDA和LIWC来表征相关的话语，通过定量和定性的比较相结合产生的见解。调查结果包括：（1）疫情期间，阴谋论占主导的Reddit评论比例超过其他任何主题;（2）每个子站都有自己的用户群，一个子站发布的信息可能无法达到其他子站发布的信息;（3）由于用户的关注点在不同时间和子站都有不同，因此必须根据具体需求调整沟通策略。本研究的结果表明，在设计有效的沟通和免疫规划的过程中，挑战和机遇。
It has been one year since the outbreak of the COVID-19 pandemic. The good news is that vaccines developed by several manufacturers are being actively distributed worldwide. However, as more and more vaccines become available to the public, various concerns related to vaccines become the primary barriers that may hinder the public from getting vaccinated. Considering the complexities of these concerns and their potential hazards, this study is aimed at offering a clear understanding about different population groups' underlying concerns when they talk about COVID-19 vaccines—particularly those active on Reddit. The goal is achieved by applying LDA and LIWC to characterize the pertaining discourse with insights generated through a combination of quantitative and qualitative comparisons. Findings include the following: (1) during the pandemic, the proportion of Reddit comments predominated by conspiracy theories outweighed that of any other topics; (2) each subreddit has its own user bases, so information posted in one subreddit may not reach that from other subreddits; and (3) since users' concerns vary across time and subreddits, communication strategies must be adjusted according to specific needs. The results of this study manifest challenges as well as opportunities in the process of designing effective communication and immunization programs.
