BACKGROUND
Vaccine hesitancy is a phenomenon that can interfere with the expansion of vaccination coverage and is positioned as one of the top 10 global health threats. Previous studies have explored factors that affect vaccine hesitancy, how it behaves in different locations, and the profile of individuals in which it is most present. However, few studies have analyzed the volatility of vaccine hesitancy.
OBJECTIVE
Identify the volatility of vaccine hesitancy manifested in social media.
METHODS
Twitter's academic application programming interface was used to retrieve all tweets in Brazilian Portuguese mentioning the COVID-19 vaccine in 3 months (October 2020, June 2021, and October 2021), retrieving 1,048,576 tweets. A sentiment analysis was performed using the Orange software with the lexicon Multilingual sentiment in Portuguese.
RESULTS
The feelings associated with vaccine hesitancy were volatile within 1 month, as well as throughout the vaccination process, being positioned as a resilient phenomenon. The themes that nurture vaccine hesitancy change dynamically and swiftly and are often associated with other topics that are also affecting society.
CONCLUSION
People that manifest the vaccine hesitancy present arguments that vary in a short period of time, what demand that government strategies to mitigate vaccine hesitancy effects be agile and counteract the expressed fear, by presenting scientific arguments.
背景
疫苗犹豫是一种可能干扰疫苗接种覆盖率扩大的现象，被列为全球十大健康威胁之一。先前的研究已经探讨了影响疫苗犹豫的因素、其在不同地点的表现方式以及最容易出现疫苗犹豫的个体特征。然而，很少有研究分析过疫苗犹豫的波动性。
目的
在社交媒体上识别出疫苗犹豫的波动性。
方法
使用 Twitter 的学术应用程序编程接口检索了在 3 个月内（2020 年 10 月、2021 年 6 月和 2021 年 10 月）提到 COVID-19 疫苗的所有巴西葡萄牙语推文，共检索到 1048576 条推文。使用 Orange 软件和 Multilingual sentiment 葡萄牙语词典进行情感分析。
结果
在 1 个月内以及整个疫苗接种过程中，与疫苗犹豫相关的情绪都是波动的，这表明疫苗犹豫是一种具有弹性的现象。助长疫苗犹豫的主题在不断变化和迅速发展，并且常常与其他也在影响社会的主题相关联。
结论
表现出疫苗犹豫的人会在短时间内提出不同的观点，这就要求政府采取灵活的策略来减轻疫苗犹豫的影响，通过提出科学论据来对抗表达出的恐惧。
