Analyzing the Impacts of COVID-19 Vaccine Research Outputs: An Altmetric Approach

Abstract

This study aimed to investigate the attention given to scientific outputs about COVID-19 vaccines worldwide on social media. It utilized scientometrics and altmetrics indicators. A dataset with 12,364 works indexed in the WOS database from 2020 to 2022 was analyzed. Altmetric Scores (AS) and Altmetrics were extracted from Altmetric Explorer. Data analysis was performed using Access, Excel, and SPSS software. The retrieved articles garnered attention on 13 social media platforms. The highest amount of social attention, accounting for 97% of the total, was related to X (Twitter) and Mendeley. The highest AS (43,765) was for an open-access article entitled "Covid-19: Researcher blows the whistle on data integrity issues in Pfizer's vaccine trial: Video 1" in the BMJ cited in 14 social media. The most productive countries in COVID-19 vaccine research were the USA, England, and China, while Harvard University, the University of London, and the University of California emerged as the most active research institutes. The findings confirmed a significant, moderate, and positive correlation between the AS and most Altmetrics with the number of citations. Additionally, a positive, substantial, and moderate correlation was observed between citations, the AS of highly-cited papers, and the AS of hot documents. Considering the positive impact of social media on increasing the chance of receiving more citations for articles and improving the impact range of articles from academic users to social users, the activities of researchers in social media are effective in increasing the visibility of scientific works.
