Manufacturing Technology and Effectiveness of Corona Vaccines: A Bibliometric Review

The etiology of "Covid-19," a respiratory illness, was first identified in late 2019 as the causative agent of the novel coronavirus. The conclusion of the pandemic was declared in 2023, and during this interval, a range of vaccines employing diverse strategies were developed. The effectiveness and other immunological characteristics of these vaccines have been thoroughly evaluated. The publication of documents related to the vaccines has persisted even after the conclusion of the pandemic. This study was conducted to investigate the research process and published documents related to the manufacturing technology and effectiveness of the vaccines. The documents published in the Scopus database in early 2024 were collected using restrictions in four subject areas and the English language. The bibliographic analysis was conducted using the Bibliometrix package in Rstudio and VOSviewer. A total of 2,810 documents were reviewed. The majority of these documents were articles and reviews, with 2,320 and 394 documents falling into these categories, respectively. Peptides and capillary electrophoresis emerged as prominent subjects in 2024. Furthermore, elasomeran, covilo, and tozinameran emerged as more recent than other keywords based on their temporal distribution. This study examines the documents published in one of the most reliable databases of vaccines against the novel strain of severe acute respiratory syndrome (SARS-CoV-2) from a bibliometric perspective. The findings of this study are expected to provide valuable insights and direction for future research initiatives, opportunities, and challenges in this field.
