最近关于戴口罩和接种疫苗以减缓2019年冠状病毒疾病传播的争议突显了个人权利和决策有可能在社区一级创造广泛的结果。很少有工作表明缓解大流行努力的集体溢出效应。作者通过可视化假想社区中未接种疫苗的人在戴口罩和接种疫苗的不同组合中感染的比例做出了贡献。在所有假设中都出现了一个共同的模式：低于口罩和疫苗接种率的某个联合门槛，几乎所有未接种疫苗的人最终都会感染，超过这个门槛，会出现急剧下降，导致社区层面的广泛保护。不同设置的不同之处在于超过阈值后下降的时间和形状。作者的结论是，掩蔽和接种疫苗是明智的，符合人群的最佳利益。
Recent controversies about wearing masks and getting vaccinated to slow the spread of coronavirus disease 2019 highlight the potential for individual rights and decision making to create widespread community-level outcomes. There is little work demonstrating the collective spillover effects of pandemic mitigation efforts. The authors contribute by visualizing the proportion of unvaccinated people who would become infected at different combinations of mask wearing and vaccination in a hypothetical community. A common pattern emerges across all assumptions: below some joint threshold of mask and vaccination rates, almost all unvaccinated people will eventually become infected, and beyond that threshold there is a steep drop leading to widespread community-level protection. What differs across settings is the timing and shape of the drop-off after crossing the threshold. The authors conclude that masking and vaccination are sensible and in the best interest of the population.
