Background: Zoonotic diseases are common diseases between humans and animals that are caused by a pathogen. The cause of the Covid-۱۹ pandemic is a virus from the Coronaviridae family that can cause respiratory disease in humans (۱). The end of this pandemic was announced in ۲۰۲۳. From the beginning to the end of the coronavirus pandemic, research was conducted in some countries and the results were published. These investigations continue to this day. One of the trending topics in the field of Covid-۱۹ is the topic based on disease prevention such as vaccines. Nucleic acid-based, inactivated, virus-like particles, and live attenuated virus vaccines were candidates for Covid-۱۹ Covid-۱۹, a respiratory disease, first emerged in late ۲۰۱۹ as the causative agent of the coronavirus. The end of this pandemic was announced in ۲۰۲۳, and during this period, various vaccines with different strategies were made. The effectiveness and other immunological characteristics of these vaccines have been tested. The publication of documents related to the Covid-۱۹ vaccines has continued until after the pandemic has ended.Objectives: This study was conducted to investigate the research process and published documents related to the manufacturing technology and effectiveness of Covid-۱۹ vaccines.Methods: The documents published in the Scopus database in early ۲۰۲۴ were collected using restrictions in ۴ subject areas and the English language. The bibliographic analysis was done using Bibliometrix-package in Rstudio and VOSviewer.Results: A total of ۲۸۱۰ documents were reviewed. Most of the documents are articles and reviews, ۲۳۲۰ and ۳۹۴ respectively. Peptides and capillary electrophoresis are trending topics in ۲۰۲۴. Additionally, elasomeran, covilo, and tozinameran are more recent than other keywords based on time.Conclusions: This study examines the documents published in one of the most reliable databases of Covid-۱۹ vaccines from a bibliometric perspective. The obtained results help other researchers and scientists in future research, opportunities, and challenges.
