Abstract

The misinformation circulating on social media regarding the coronavirus pandemic has been a obstacule in the fight against the disease, directly impacting the advancement of immunization in various parts of the world. This study sought to evaluate possible influences between vaccination rates in Brazil and social media interactions related to posts from questinable sources. Using econometric models, we measured the impact of questionable information about vaccines, considering geographic, political and social issues. The results show a negative impact on vaccination rates, with different variations depending on the political orientation of the posts considered, as well as a geographic inequality in terms of vulnerability to misinformation.

巴西冠状病毒疫苗接种错误信息分析
社交媒体上流传的关于冠状病毒大流行的错误信息是抗击该疾病的障碍,直接影响了世界各地免疫工作的进展。本研究旨在评估巴西疫苗接种率与与可疑来源的帖子相关的社交媒体互动之间可能产生的影响。考虑到地理、政治和社会问题,我们使用计量经济模型测量了有关疫苗的可疑信息的影响。结果显示,疫苗接种率受到负面影响,根据所考虑的职位的政治倾向而有不同的变化,而且在易受错误信息影响方面存在地域不平等。
