COVID-19的治愈、治疗和疫苗：Twitter上的国际兴趣差异
Cures, Treatments and Vaccines for Covid-19: International differences in interest on Twitter
摘要：
由于新型冠状病毒肺炎（COVID-19，即2019冠状病毒病）大流行是一个全球性的健康威胁，很少有人能完全逃脱，因此它为研究国际社会对一个共同问题的反应提供了一个独特的机会。这种反应可以部分地从Twitter的公开帖子中获得，从而可以调查随着时间的推移兴趣的变化。这项研究分析了2020年1月1日至2021年4月8日期间提到治愈、治疗或疫苗的英文推文，以寻求趋势和国际差异。结果有方法上的局限性，但显示出人类发展指数得分较低的国家在推特上更多地谈论治疗的趋势，尽管这对所有国家来说都是一个次要话题。直到2020年7月，疫苗的讨论与治疗一样多，当时由于俄罗斯的发展，疫苗引起了更多的兴趣。然而，2020年11月辉瑞-BioNTech初步3期试验结果产生了立即和持续的大幅增长，随后对疫苗的兴趣持续大致线性增长，直到至少2021年4月。在此背景下，各国与平均值的偏差是由各国有关治愈、治疗或疫苗的新闻引发的。尽管如此，尽管各国在国家监管批准和供应方面存在巨大的国际差异，但所有国家对疫苗的兴趣在一定程度上平行增加。调查结果还突出表明，关于替代医学补救措施的未经证实的说法在几个国家获得了支持，显然对公共健康构成了威胁。
英文摘要：
Since the Covid-19 pandemic is a global threat to health that few can fully escape, it has given a unique opportunity to study international reactions to a common problem. Such reactions can be partly obtained from public posts to Twitter, allowing investigations of changes in interest over time. This study analysed English-language Covid-19 tweets mentioning cures, treatments, or vaccines from 1 January 2020 to 8 April 2021, seeking trends and international differences. The results have methodological limitations but show a tendency for countries with a lower human development index score to tweet more about cures, although they were a minor topic for all countries. Vaccines were discussed about as much as treatments until July 2020, when they generated more interest because of developments in Russia. The November 2020 Pfizer-BioNTech preliminary Phase 3 trials results generated an immediate and sustained sharp increase, however, followed by a continuing roughly linear increase in interest for vaccines until at least April 2021. Against this background, national deviations from the average were triggered by country-specific news about cures, treatments or vaccines. Nevertheless, interest in vaccines in all countries increased in parallel to some extent, despite substantial international differences in national regulatory approval and availability. The results also highlight that unsubstantiated claims about alternative medicine remedies gained traction in several countries, apparently posing a threat to public health.
