Due to COVID-19, people's lives have changed greatly. In accordance with former experience, an efficacious vaccine is the most effective way to curb the pandemic; thus, many researchers have published related publications in the short term. Hence, this study aims at using bibliometric analysis and visualization to document research trends regarding COVID-19 vaccines, and offer some directions and suggestions for future research. Initially, all eligible publications were downloaded from Web of Science on 1 January 2022. Subsequently, some publications published before December 2019 were removed since COVID-19 did not occur before that date. Finally, Microsoft Excel is used for bibliometric analysis to analyze publication date, author, affiliation, country, publication title, publisher, research area, document type, and language, and visualized software (VOSviewer) is used to visualize author, affiliation, country, and keywords. After analyzing a total of 17,392 publications, the results show that the overall research trend was upward. Moreover, the prominent authors, institutions, and countries inclined towards regional cooperation instead of international cooperation. Furthermore, the most popular research areas were immunology and medicine (general and internal). Ultimately, COVID-19, vaccine, and SARS-CoV-2 were the top 3 keywords. In conclusion, this study shows the approximate research trend for COVID-19 vaccine during the completely first two years of the pandemic. The research focuses moved from safety, effectiveness, and immunology at the early stage to the optimal allocation strategies for COVID-19 vaccine, and eventually to public attitudes and acceptance towards COVID-19 vaccination.
由于新冠疫情，人们的生活发生了巨大变化。根据以往经验，有效的疫苗是遏制疫情最有效的方法；因此，许多研究人员在短期内发表了相关出版物。因此，本研究旨在利用文献计量分析和可视化方法记录新冠疫苗的研究趋势，并为未来研究提供一些方向和建议。最初，所有符合条件的出版物于2022年1月1日从Web of Science下载。随后，一些2019年12月之前发表的出版物被剔除，因为新冠疫情在此日期之前尚未发生。最后，使用Microsoft Excel进行文献计量分析，以分析出版日期、作者、机构、国家、出版物标题、出版商、研究领域、文献类型和语言，并使用可视化软件（VOSviewer）对作者、机构、国家和关键词进行可视化。在分析了总共17392篇出版物后，结果表明总体研究趋势呈上升趋势。此外，杰出的作者、机构和国家倾向于区域合作而非国际合作。此外最受欢迎的研究领域是免疫学和医学（普通医学和内科学）。最终，新冠、疫苗和严重急性呼吸综合征冠状病毒2是排名前三的关键词。总之，本研究展示了疫情头两年新冠疫苗的大致研究趋势。研究重点从早期的安全性、有效性和免疫学，转向新冠疫苗的优化分配策略，最终转向公众对新冠疫苗接种的态度和接受度。
