@berman_allen @ai6yrham May 2021 didn't have verification. It might have worked better (at least for a while) if it did.
But this is fighting the last war. A vaccine exemption to a transmission-reducing mitigation when vaccine doesn't stop transmission = dumb.
2021年5月的贝尔曼纳艾伦@艾哈伊姆没有得到证实。如果真是这样的话，它可能会运行得更好（至少在一段时间内）。
但这是在打最后一场战争。当疫苗不能阻止传播时，疫苗对减少传播缓解的豁免=哑巴。
