开发有效的COVID-19疫苗被广泛认为是结束当前健康危机的最佳途径之一。虽然短期内分发疫苗的能力仍然不确定，但仅靠疫苗的供应不足以阻止疾病的传播。相反，政策制定者需要克服快速广泛采用的额外障碍。在一项具有全国代表性的大规模调查（N = 34，200）中，目前的工作将货币风险偏好确定为预期COVID-19疫苗接种的相关因素。一项补充实验（N = 1，003）利用这一洞察力创建了鼓励疫苗接种的有效信息。风险偏好的个体差异会缓和对提供疫苗效力基准（通过将其与流感疫苗进行比较）的信息的反应，而描述疫苗接种（特别是群体免疫）的亲社会益处的信息则会加速疫苗接种，而无论风险偏好如何。研究结果表明，政策制定者在针对疫苗相关传播时应考虑风险偏好。
Development of an effective COVID-19 vaccine is widely considered as one of the best paths to ending the current health crisis. While the ability to distribute a vaccine in the short-term remains uncertain, the availability of a vaccine alone will not be sufficient to stop disease spread. Instead, policy makers will need to overcome the additional hurdle of rapid widespread adoption. In a large-scale nationally representative survey (N = 34,200), the current work identifies monetary risk preferences as a correlate of take-up of an anticipated COVID-19 vaccine. A complementary experiment (N = 1,003) leverages this insight to create effective messaging encouraging vaccine take-up. Individual differences in risk preferences moderate responses to messaging that provides benchmarks for vaccine efficacy (by comparing it to the flu vaccine), while messaging that describes pro-social benefits of vaccination (specifically herd immunity) speeds vaccine take-up irrespective of risk preferences. Findings suggest that policy makers should consider risk preferences when targeting vaccine-related communications.
