Background: Vaccination programs are effective only when a significant percentage of people are vaccinated. However, vaccine acceptance varies among communities around the world. Social media usage is arguably one of the factors affecting public attitudes towards vaccines. Objective: This study aims to identify if the social media usages factors can be used to predict attitudes and behavior towards the COVID-19 vaccines among the people in the Arab world. Methods: An online survey was conducted in the Arab countries and 217 Arab people participated in this study. Logistic regression was applied to identify what demographics and social media usage factors predict public attitudes and behavior towards the COVID-19 vaccines. Results: Of the 217 participants, 56.22% of them were willing to accept the vaccine and 41.47% of them were hesitant. This study shows that none of the social media usages factors were significant enough to predict the actual vaccine acceptance behavior. Whereas the analysis showed few of the social media usage factors can predict public attitudes towards the COVID-19 vaccines. For example, frequent social media users were 2.85 times more likely to agree that the risk of COVID-19 is being exaggerated (OR=2.85, 95% CI=0.86-9.45, p=0.046) than infrequent social media users. Whereas participants having more trust in vaccine information shared by their contacts are less likely to agree that decision-makers have verified that vaccines are safe (OR=0.528, 95% CI= 0.276-1.012, p=0.05). Conclusion: The use of social media and information shared on it may affect public attitudes towards COVID-19 vaccines. Therefore, disseminating correct and validated information about COVID-19 and other vaccines on social media is important for increasing public trust and countering the impact of incorrect and misinformation.

对疫苗接种的态度变得更加两极分化;在网上看到疫苗虚假信息和边缘阴谋论是很常见的。Ojea Quintana et al.（2021）对Twitter疫苗话语进行了观察性研究：作者分析了大约六个月的Twitter话语-2019年12月至2020年6月期间的130万条原始推文和1800万条转发，范围从新冠肺炎大流行之前到之后。这项工作扩展了Ojea Quintana et al.（2021）的数据科学的两个主要贡献。首先，基于作者最初的网络聚类和定性分析技术，我们能够清楚地划分和可视化话语中使用的语言模式，由反疫苗接种运动者（反疫苗接种运动者和疫苗否认者）与其他集群（统称，其他人）。其次，利用Antivaxxers的推文的特点，我们开发了文本分类器来确定给定用户使用反疫苗接种语言的可能性，最终有助于建立一个早期预警机制，以改善我们的认知环境的健康状况，并支持（而不是阻碍）公共卫生举措。
