Objectives:

to analyze the bibliometry of the scientific evidence of the main 6 Covid-19 vaccines (Sputnik V, Moderna, Pfizer, Sinopharm, AstraZeneca, Janssen).

Methods:

data collection was carried out through the use of boolean searches on the Pubmed and Google Scholar search engines, in order to filter all published randomized clinical trials for each vaccine, following the recommendations of GRADE in relation to the level of evidence (category A), subsequently the database was processed for visualization of the analysis using: Excel, Scimago Graphica and Vosviewer.

Results:

47 randomized clinical trials (category A of scientific evidence, GRADE) of the 6 mentioned vaccines were taken into account, it is shown that the Pfizer vaccine has the greatest number of publications, as well as global citations, unlike the production of scientific evidence of the other vaccines, it is found that the country of origin of the authors with the most prevalence was the United States, United Kingdom and Netherlands, in relation to the journals where they had the most publications they were The Lancet and The New England Journal of Medicine.

Conclusions:

it is visible that the already mentioned vaccines have more scientific production compared to vaccines produced in other parts of the world, such as Pfizer, AstraZeneca, among the others analyzed in this document, as well as a wider global distribution, and a extensive network of support through citations to their scientific documents.
