Impact, Trends, and Visibility of Scientific Publications on Neurological Effects of COVID-19 Vaccine: A Scientometric Analysis

Introduction:Neurological complications associated with the COVID-19 vaccine can include different neurological diseases. Although these cases are rare, it is crucial for healthcare professionals to recognize them for timely diagnosis and treatment. The aim of this study was to analyze the impact, trend, and visibility of scientific publications on the neurological effects of the COVID-19 vaccine during 2020-2023 in Scopus.Methods:A bibliometric, descriptive, and retrospective study was conducted. Through Scopus (SciVal), variables were measured objectively. Data were sought from December 2018 to August 2023. All papers on neurological effects associated with the COVID-19 vaccine were published between January 2020 and August 2023 in the Scopus database. On August 18, 2023, 65 articles were identified, of which 59 met the inclusion criteria. They were downloaded and exported in.csv format and subsequently analyzed in Microsoft Excel (R) 2019 using tables.Results:The United States was the country with the highest number of authors (six) publishing on the subject in Scopus, followed by India with two authors. In addition, it was observed that the United States was the country with the highest production, with 30 publications and 411 countable citations. However, India, being the second in scientific production, was the country with the highest impact. Of the most productive institutions, six were from the United States, with Harvard University being the institution with the highest scientific production. With respect to the journals, six obtained two publications on the subject under study, where "Journal of Neurology" and "Journal of Clinical Medicine" stand out with 100 and 80 publications, respectively.Conclusions:The bibliometric analysis reveals that the USA leads in publications on adverse neurological effects of COVID-19 vaccine. India stands out for its impact, especially through institutions such as Ahmedabad Civil Hospital and B. J. Medical College. It is suggested to expand the research to other databases.
