This study attempted to draw the present and future perspective of the COVID-19 vaccine by identifying the most important scientists and their scientific contexts, trends of research topics, and relationships between different entities. Methods: To achieve this purpose, bibliometric and scientometric techniques were used to analyze 6288 scientific documents contributing to COVID-19 vaccines from the beginning of 2019 to 13 December 2021, indexed in the Web of Science. Results: The United States (US) had the greatest impact by publishing 2104 documents and receiving 32,958 citations. The US and the UK countries had the highest level of scientific collaborations with 192 collaborative studies. The University of Oxford and the Harvard Medical School were the most active institutions, and the University of Oxford and Emory University were the most influential institutions. Pollard AJ and Lambe T had the most publications and the highest citations and h-index. T Lambe, SC Gilbert, M Voysey, and AJ Pollard from the University of Oxford had the highest number of co-authorships. More than 19% of the research was conducted in the field of immunology. The Vaccines journal had the most publications, with 425 articles. The US Department of Health & Human Services granted the most research. In 2019, studies were focused on the topics of COVID-19 virus identification and ways to deal with it; in 2020, studies focused on the topics of COVID-19 and vaccines, whereas in 2021, they focused on the topics of COVID-19 vaccines and their effects, vaccines hesitancy, the role of healthcare workers in COVID-19, as well as discussions about these vaccines in the social media. Conclusions: Recognition of the most important actors (countries, institutes, researchers, and channels for the release of COVID-19 vaccine studies), research trends, and fields of study on the COVID-19 vaccine can be useful for researchers, countries, and policy makers in the field of science and health to make decisions and better understand these vaccines.

Background and Aim:The purpose of the present study is thematic analysis and scientific collaborations of research related to COVID-19 vaccine in Iran and the world based on scientific products indexed in Web of Science (WOS). Materials and Methods:The present study is a descriptive-analytical study with a scientometric approach and using the methods of content analysis and techniques of co-word analysis, hierarchical clustering, Strategic graph and social network analysis. The research population is scientific products related to COVID-19 vaccine in the world and in Iran. Data analysis was performed by HistCite, Bibexecl, Gephi and SPSS software; and the data mapping is done by VOS viewer. Results: Between 2019 and 2021, 6005 related studies were retrieved. Unites states is followed by India and China, and the United Kingdom has the most Links. Iran's rank is 10th with 196 studies. Hierarchical clustering in global research led to the formation of 3 clusters (vaccine development strategy, medical prevention and immunotherapy) and in Iranian research led to the formation of 4 clusters (immunotherapy, diagnosis and treatment cycle, medical prevention and immunology). From scientific collaborations at the country level in world and Iranian studies, 5 clusters were formed, at the level of institutions, 17 and 10 clusters, respectively, and at the level of researchers, 10 and 8 clusters, respectively. Conclusion: Analysis and comparison of world and Iranian studies leads to a better understanding of the prevailing currents, Gaps and discourse in order to increase the quantity and quality of studies, followed by controlling and the eradication of COVID-19 in the shortest possible time.

Background and Aim: This study aimed to investigate the role and application of medical and health archives in scientific research based on research topics indexed in WOS. Materials and Methods:This study was a descriptive study with a scientometrics approach and the method of co-word analysis and hierarchical clustering and Strategic graph. The research population was scientific products on medical and health archives. Data analysis was performed by HistCite, Bibexecl, UCINET, Excel and SPSS software.Results: In the last three decades, 323 related studies were retrieved. The research dissemination has been increasing with an average annual growth rate of 34.87%. The United States and Univ Pittsburgh were ranked first in terms of publishing and citation rates. Iran ranks 14th with 7 researches. The field of GENERAL INTERNAL MEDICINE has had the largest share of 41 research among 88 participating research areas. The mortality keyword has the most frequency. Co-word clustering in medical archival research led to the formation of 7 clusters. Findings from the calculation of the density and centrality scores showed that "Cluster 3: smart Medicine" has the highest centrality and "Cluster 6: Open Data" has the highest density score. Conclusion:Medical archives play an important role in discovering the causes of mortality and subsequently reducing mortality, preventing diseases and their risks and prevalence, improving diagnoses, treatments, and ultimately improving the health system.
