How does the public want a COVID-19 vaccine to be allocated? We conducted a conjoint experiment asking 15,536 adults in 13 countries to evaluate 248,576 profiles of potential vaccine recipients who varied randomly on five attributes. Our sample includes diverse countries from all continents. The results suggest that in addition to giving priority to health workers and to those at high risk, the public favors giving priority to a broad range of key workers and to those with lower income. These preferences are similar across respondents of different education levels, incomes, and political ideologies, as well as across most surveyed countries. The public favored COVID-19 vaccines being allocated solely via government programs but were highly polarized in some developed countries on whether taking a vaccine should be mandatory. There is a consensus among the public on many aspects of COVID-19 vaccination, which needs to be taken into account when developing and communicating rollout strategies.

公众希望如何分配 COVID-19 疫苗？我们进行了一项联合实验，要求 13 个国家/地区的 15,536 名成年人评估 248,576 份在五个属性上随机变化的潜在疫苗接种者的概况。我们的样本包括来自各大洲的不同国家。结果表明，除了优先考虑卫生工作者和高危人群外，公众还倾向于优先考虑范围广泛的关键工作者和低收入人群。这些偏好在不同教育水平、收入和政治意识形态的受访者以及大多数接受调查的国家中是相似的。公众支持仅通过政府计划分配的 COVID-19 疫苗，但在某些发达国家是否应强制接种疫苗的问题上存在高度两极分化。
