@4stroboy__ @Nutmeg031992 @CS_nft @spectatorindex No it isn't assuming that.
It is assuming that if vaccines did absolutely nothing (pure placebo), deaths/pop in the population would match deaths/pop in vaccinated (+/- statistical noise).
Reality: Deaths/pop in population > deaths/pop in vaccinated.
= Vaccines working
@4stroboy_uuu@Nutmag031992@CS_nft@CobstorIndex不，这不是假设。
假设如果疫苗完全不起作用（纯安慰剂），人群中的死亡/流行性感冒将与接种疫苗的死亡/流行性感冒相匹配（+/-统计噪声）。
现实：人口中的死亡/流行性感冒>；接种疫苗后的死亡/流行性感冒。
=疫苗有效
