其次,计算方式 作者的看法是依据目前公开的疫苗部分数据摘要 wojournalpublicationsand around 400 pages of summary data are available in the form ofmultiplereportspresentedbyandtotheFDAprior to the agency’s emergency authorization of each company’s mRNA vaccine. 在辉瑞疫苗的数据中,疫苗组和对照组分别出现了8和162例新冠患者,因此当时辉瑞提出自己的疫苗有效性很高。 然而,这背后出现了一个很大的bug,那就是,高达3410例有新冠症状的人被排除在外了。 其中,1594例出现在了疫苗组,1816例出现在了对照组。 3410 total cases of suspected, but unconfirmed covid-19 in the overall study population, 1594 occurred in the vaccine group vs. 1816 in the placebo group.” 这些患者的症状符合新冠,当时PCR并没有确诊,也就是我们经常说的疑似病例(“suspected covid-19”),然而,这些病例被辉瑞直接排除了。 这就有意思了,因为根据目前pcr检测中常见的问题,疑似病例最终确诊的比例并不低,这意味着辉瑞极有可能把大量的真实感染者给排除在结果之外了。 如果这些疑似患者全部被确诊后纳入到辉瑞的总数据中。 那么,最粗略的估计,疫苗有效率只有19% A rough estimate of vaccine efficacy against developing covid-19 symptoms, with or without a positive PCR test result, would be a liba risk reduction of 19% 即便排除掉注射后7天内的确诊患者,疫苗的有效率也只有29%。 Even after removing cases occurring within 7 days of vaccination (409 on Pfizer’s vaccine vs. 287 on placebo), which should include the majority of symptoms due to short-term vaccine reactogenicity, vaccine efficacy remains low: 29% 作者附上了计算办法: Calculations in this article are as follows: 19% = 1 – (8+1594)/(162+1816); 29% = 1 – (8 + 1594 – 409)/(162 + 1816 – 287). I ignored denominators as they are similar between groups.
