目的本研究旨在揭示COVID-19疫苗在日本推特圈的接受情况。本研究探讨了如何在Twitter上的疫苗推广项目相关的主题发生了变化，以及如何在疫苗推广项目期间可能传播的主题发生了变化。本研究使用Twitter API收集了2021年3月至10月期间所有包含“疫苗”一词的推文，并进行了以下分析：分析频繁词汇，并通过余弦相似度和Tobit模型识别可能传播的主题。第二，与疫苗接种相关的词汇在4月至5月期间经常被提及和传播，并在整个期间具有扩散力。这些研究结果的背景是，渴望疫苗的情绪超过了对疫苗的犹豫在此期间。独创性/valueThis研究发现，疫苗犹豫情绪的上升时间和疫苗供应的开始时间不一致。这也是原本表现出强烈疫苗犹豫情绪的日本在COVID-19疫苗推广项目中没有面临疫苗犹豫的原因之一。
PurposeThis study aims to reveal how the COVID-19 vaccine was accepted in the Japanese Twitter-sphere. This study explores how the topics related to the vaccine promotion project changed on Twitter and how the topics that were likely to spread changed during the vaccine promotion project.Design/methodology/approachThe computational social science methodology was adopted. This study collected all tweets containing the word “vaccine” using the Twitter API from March to October 2021 and conducted the following analysis: analyzing frequent words and identifying topics likely to spread through the cosine similarity and Tobit model.FindingsFirst, vaccine hesitancy–related words were frequently mentioned during the vaccine introduction and dissemination periods and had diffusing power only during the former period. Second, vaccine administration–related words were frequently mentioned and diffused through April to May and had diffusing power throughout the period. The background to these findings is that the sentiment of longing for vaccines outweighed that of hesitancy toward vaccines during this period.Originality/valueThis study finds that the timing of the rise in vaccine hesitation sentiment and the timing of the start of vaccine supply were misaligned. This is one of the reasons that Japan, which originally exhibited strong vaccine hesitancy, did not face vaccine hesitancy in the COVID-19 vaccine promotion project.
