研究发现,研究对象中1%感染的是南非发现的变种病毒,其中,接种了两剂辉瑞疫苗后仍确诊的患者,感染该变种病毒的机率是未接种疫苗者的近八倍,感染率分别为5.4%和0.7%。

The percentage doesn't make sense. Do the math.

我反正看不懂。你的结论是什么?
The South African variant, B.1.351, was found to make up about 1% of all the COVID-19 cases across all the people studied, according to the study by Tel Aviv University and Israel’s largest healthcare provider, Clalit.
But among patients who had received two doses of the vaccine, the variant’s prevalence rate was eight times higher than those unvaccinated - 5.4% versus 0.7%.

800 * 1% = 8

800 * 1% = 8

我的理解是原文没有给出两组各自的总感染率,而是说在打针组病例中变种占5.4%, 而没打组变种占0. ...
The study, released on Saturday, compared almost 400 people who had tested positive for COVID-19, 14 days or more after they received one or two doses of the vaccine, against the same number of unvaccinated patients with the disease.

翻车点可能不同,是在于辉瑞疫苗可能暗含某种指定病毒的特殊通道,刚好被南非变异周走通了 ...

也许是因为疫苗对未变异株更加有效,从而使突变株获得了相对的竞争优势。未必是疫苗“帮助”了突变株。 ...

800人感染,1%是南非变种,就是8个人。其中大概3个属于打过疫苗的55人组;5个人属于没打疫苗的745人组。。 ...

这个55人组和745人组是怎么算出来的?
独角兽 发表于 2021-4-11 22:39
根据这不靠谱的文章猜出来的。1~7,2~6,3~5。分别除以各自百分比。加起来是800的就差不多猜对了。 ...

这是凑数的算法,但文章里确实说到400人是接种过疫苗的啊。所以这些数字碰不起来,叫人抓狂。莫不是被文 ...

我刚刚没点开原文看,或者那个链接是实验本身文章还是一个不怎么靠谱的解读。因为总数800人,1%是8个人南 ...

接受疫苗后的患者中,因为疫苗对其他变种抵抗性更高,于是就显得感染南非变种的几率比一般人群高。但实际两 ...
