既然你提到智利https://www.straitstimes.com/world/chilean-study-shows-variations-in-success-of-covid-19-vaccines “Sinovac's Covid-19 vaccine was 58.5 per cent effective in preventing symptomatic illness among millions of Chileans who received it between February and July, the Chilean health authorities said on Tuesday (Aug 3), while Pfizer's Covid-19 shot was 87.7 per cent effective and AstraZeneca's was 68.7 per cent effective.” 他们是各种疫苗都用的。而且现实使用样本很大。也几乎是同时所以没有对各种变异的差别。看看数据，自己可以下结论。 并没有说中国疫苗不靠谱，但是也没有必要和中国奥运金牌联系在一起。 这逻辑，难道中国奥运金牌第一了，国产婴儿奶粉也会一下子销量第一了？
