Abstract

Background

With an ever growing and expanding body of literature on the newly developed vaccines against the COVID-19, there is an urgent need for a comprehensive analysis of the current state of research on vaccine effectiveness (VE). This study conducted a comprehensive bibliometric analysis to critically examine the productivity and impact of retrieved publications on COVID-19 VE and to predict the future directions of research in the field.

Methods

The global literature on COVID-19 VE from 2021 to 2024 was extracted from the VIEW-hub website. Using bibliometric analysis tools, specifically Microsoft Excel, the R package "bibliometrix, biblioshiny" and VOSviewer, we analyzed publications for trends in productivity, citations, and global collaboration. Key metrics assessed include publication and citation trends, influential authors, collaborative networks, and thematic evolution, offering a comprehensive view of the research landscape on COVID-19 VE.

Results

A total of 490 publications were authored by 5031 authors from 934 institutions and 78 countries and published in 119 journals. Most retrieved publications were original articles (99.6 %). The United States was the most productive country with 205 publications (41.8 %). Global research collaborations were mainly within developed countries. Analysis of the thematic evolution of the field illustrated changing research focus over three distinct time clusters. Throughout 2021, studies were focused on outlining infection prevention and control measures, as well as examining the efficacy of novel mRNA vaccines. In 2022, the linchpin of research was shifted towards dissecting the epidemiological correlates of the pandemic in light of the widespread use of vaccines. The final cluster showed special emphasis on the new variants of COVID-19 and the long-term outcomes of vaccines.

Conclusion

Our study identified geopolitical disparities and weak engagement from developing countries in the ongoing efforts regarding COVID-19 VE. This study can inform researchers, policymakers, and funding agencies as they assess ongoing research and future directions in COVID-19 VE.

绘制 COVID-19 疫苗有效性研究的趋势和热点：全球研究文献计量综合分析

背景随着有关新开发的COVID-19疫苗的文献数量不断增加和扩大，迫切需要对疫苗有效性（VE）的研究现状进行全面分析。本研究进行了全面的文献计量学分析，以批判性地检查检索到的有关 COVID-19 VE 的出版物的生产力和影响，并预测该领域未来的研究方向。方法从 VIEW-hub 网站提取 2021 年至 2024 年有关 COVID-19 VE 的全球文献。我们使用文献计量分析工具，特别是 Microsoft Excel、R 软件包 "bibliometrix, biblioshiny "和 VOSviewer，分析了出版物在生产率、引文和全球合作方面的趋势。评估的关键指标包括发表和引用趋势、有影响力的作者、合作网络和主题演变，从而全面了解 COVID-19 VE 的研究情况。结果来自 78 个国家 934 个机构的 5031 位作者共撰写了 490 篇出版物，发表在 119 种期刊上。检索到的大多数出版物都是原创文章（99.6%）。美国是发表论文最多的国家，共发表了 205 篇论文（占 41.8%）。全球研究合作主要集中在发达国家内部。对该领域主题演变的分析表明，研究重点在三个不同的时间段发生了变化。在整个 2021 年，研究重点是概述感染预防和控制措施，以及研究新型 mRNA 疫苗的功效。2022 年，鉴于疫苗的广泛使用，研究重点转向剖析大流行病的流行病学相关因素。最后一组研究特别强调了 COVID-19 的新变种和疫苗的长期效果。这项研究可为研究人员、政策制定者和资助机构提供信息，帮助他们评估 COVID-19 VE 的当前研究和未来发展方向。

期刊介绍： The Journal of Infection and Public Health, first official journal of the Saudi Arabian Ministry of National Guard Health Affairs, King Saud Bin Abdulaziz University for Health Sciences and the Saudi Association for Public Health, aims to be the foremost scientific, peer-reviewed journal encompassing infection prevention and control, microbiology, infectious diseases, public health and the application of healthcare epidemiology to the evaluation of health outcomes. The point of view of the journal is that infection and public health are closely intertwined and that advances in one area will have positive consequences on the other. The journal will be useful to all health professionals who are partners in the management of patients with communicable diseases, keeping them up to date. The journal is proud to have an international and diverse editorial board that will assist and facilitate the publication of articles that reflect a global view on infection control and public health, as well as emphasizing our focus on supporting the needs of public health practitioners. It is our aim to improve healthcare by reducing risk of infection and related adverse outcomes by critical review, selection, and dissemination of new and relevant information in the field of infection control, public health and infectious diseases in all healthcare settings and the community.
