We used a global mathematical model simulating different scenarios to study the effects of increased COVID-19 vaccine equity during 2021. Our results indicate that vaccine nationalism leads to increased infections and mortality worldwide, and by favoring the emergence of new viral variants, in the long term it may adversely affect all countries.

量化全球疫苗覆盖率不公平对 COVID-19 大流行的影响

我们使用模拟不同情景的全球数学模型来研究 2021 年增加 COVID-19 疫苗公平性的影响。我们的结果表明，疫苗民族主义导致全球感染和死亡率增加，并通过有利于新病毒变种的出现，从长远来看任期它可能对所有国家产生不利影响。
