Objective: The rapid dissemination of scientific information on Twitter (X) during the COVID-19 pandemic has played an important role in shaping public opinion and health decision-making. This study aims to investigate the level of scientific evidence of COVID-19 preprints shared on Twitter (X) in Brazil between 2020 and June 2023 and the impact of these shares on the public debate about the New Coronavirus pandemic in Brazil.
Method: The study mapped COVID-19 preprints from 2020 to June 2023, identifying the level of scientific evidence for each one, as well as the content of their shares on Twitter (X). Literature review, documentary research, scientific evidence analysis, content analysis and altmetric analysis procedures were used.
Results: The lower the level of scientific evidence of the preprints, the more they were shared. Messages categorized as "anti-vaccine movement" were the most recurrent and a significant proportion of users described themselves as "conservative".
Conclusions: This study found a tendency to disseminate fake and/or distorted news based on the then-eminent scientific production on the New Coronavirus pandemic. The high level of misinformation present in these shares highlighted the need for scientific information to be interpreted based on scientific evidence, as opposed to discourses contrary to science.
