The Coronavirus disease; COVID-19 vaccines will not end the pandemic if they stay in freezers. In many countries, such as France, COVID-19 vaccines hesitancy is high. It is crucial that governments make it as easy as possible for people who want to be vaccinated to do so, but also that they devise communication strategies to address the concerns of vaccine hesitant individuals. We introduce and test on 701 French participants a novel messaging strategy: A chatbot that answers people's questions about COVID-19 vaccines. We find that interacting with this chatbot for a few minutes significantly increases people's intentions to get vaccinated (ß = 0.12) and has a positive impact on their attitudes toward COVID-19 vaccination (ß = 0.23). Our results suggest that a properly scripted and regularly updated chatbot could offer a powerful resource to help fight hesitancy toward COVID-19 vaccines.

聊天机器人传递的信息对人们对 COVID-19 疫苗的态度和意图产生积极影响。

冠状病毒病；如果将 COVID-19 疫苗放在冰箱中，就无法结束这场大流行。在法国等许多国家，人们对 COVID-19 疫苗犹豫不决。至关重要的是，政府应让想要接种疫苗的人尽可能方便地接种疫苗，而且还应制定沟通策略来解决对疫苗犹豫不决的个人的担忧。我们引入了一种新颖的消息传递策略，并在 701 名法国参与者身上进行了测试：一个可以回答人们有关 COVID-19 疫苗问题的聊天机器人。我们发现，与该聊天机器人交互几分钟可显着提高人们接种疫苗的意愿 (ß = 0.12)，并对他们对 COVID-19 疫苗接种的态度产生积极影响 (ß = 0.23)。我们的结果表明，脚本正确且定期更新的聊天机器人可以提供强大的资源，帮助消除人们对 COVID-19 疫苗的犹豫不决。（PsycInfo 数据库记录 (c) 2023 APA，保留所有权利）。
