Vaccine hesitancy (VH) is defined as a delayed in acceptance or refusal of vaccines despite availability of vaccination services. This multinational study examined user interaction with social media about COVID-19 vaccination. The study analyzed social media comments in 24 countries from five continents. In total, 5856 responses were analyzed; 83.5% of comments were from Facebook, while 16.5% were from Twitter. In Facebook, the overall vaccine acceptance was 40.3%; the lowest acceptance rates were evident in Jordan (8.5%), Oman (15.0%), Senegal (20.0%) and Morocco (20.7%) and the continental acceptance rate was the lowest in North America 22.6%. In Twitter, the overall acceptance rate was (41.5%); the lowest acceptance rate was found in Oman (14.3%), followed by USA (20.5%), and UK (23.3%) and the continental acceptance rate was the lowest in North America (20.5%), and Europe (29.7%). The differences in vaccine acceptance across countries and continents in Facebook and Twitter were statistically significant. Regarding the tone of the comments, in Facebook, countries that had the highest number of serious tone comments were Sweden (90.9%), USA (61.3%), and Thailand (58.8%). At continent level, serious comments were the highest in Asia (58.4%), followed by Africa (46.2%) and South America (46.2%). In Twitter, the highest serious tone was reported in Egypt (72.2%) while at continental level, the highest proportion of serious comments was observed in Asia (59.7%), followed by Europe (46.5%). The differences in tone across countries and continents in Facebook and Twitter and were statistically significant. There was a significant association between the tone and the position of comments. We concluded that the overall vaccine acceptance in social media was relatively low and varied across the studied countries and continents. Consequently, more in-depth studies are required to address causes of such VH and combat infodemics.
疫苗犹豫（VH）是指尽管可获得疫苗接种服务，但仍延迟接受或拒绝疫苗。这项多国家研究检查了用户在社交媒体上对 COVID-19 疫苗接种的互动情况。该研究分析了来自五个大洲的 24 个国家的社交媒体评论。总共分析了 5856 条回复；83.5%的评论来自 Facebook，而 16.5%来自 Twitter。在 Facebook 中，整体疫苗接受率为 40.3%；在约旦（8.5%）、阿曼（15.0%）、塞内加尔（20.0%）和摩洛哥（20.7%）的接受率最低，而在北美，接受率最低，为 22.6%。在 Twitter 中，总体接受率为（41.5%）；在阿曼（14.3%）发现最低的接受率，其次是美国（20.5%）、英国（23.3%），在北美（20.5%）和欧洲（29.7%）的接受率最低。在 Facebook 和 Twitter 中，各国和各大陆之间疫苗接受率的差异具有统计学意义。关于评论的语气，在 Facebook 中，具有最高数量的严肃语气评论的国家是瑞典（90.9%）、美国（61.3%）和泰国（58.8%）。在大陆一级，亚洲的严肃评论最高（58.4%），其次是非洲（46.2%）和南美洲（46.2%）。在 Twitter 中，埃及报告的最高严肃语气为 72.2%，而在大陆一级，亚洲观察到的最高比例严肃评论为 59.7%，其次是欧洲（46.5%）。在 Facebook 和 Twitter 中，各国和各大陆之间的语气差异具有统计学意义。语气和评论位置之间存在显著关联。我们得出的结论是，社交媒体中整体疫苗接受率相对较低，并且在研究国家和大陆之间存在差异。因此，需要进行更深入的研究来解决这种 VH 的原因，并应对信息疫情。
