  • 枫下家园 / 医药保健 / 算道题, 估算一下1个million人口的城市会有多少break through 感染和死亡人数? +2

    基本数据和假设: 人口1M, 感染率 4.4% (加拿大数据), 死亡率 1.7% (加拿大数据), 完全疫苗接种率 70%, 疫苗有效性(CDC): 降低感染率 6倍, 降低死亡率 11 倍。

    局限性: 政府数据, fake media, 不考虑太多的复杂性, 比如感染率死亡率包括了整个pandemic的数据, 疫苗有效率没有年龄框框。疫苗的有效性随时间变化不做考虑 。 总之 又粗又raw, 只是个信封背后的估计, 不能要求太高。一贯粗心, 计算如有错误, 请指正。

    70%接种人群, 假如没接种, 感染人数应该是700000 x 4.4%= 30800, 死亡人数 30800x 1.7%= 524. 这些人接种了疫苗, break thru感染人数 30800/6=5133, break thru 死亡人数 524/11= 48

    所以从绝对人数上, 一个1M人口的城市 会看到 5133 个完全接种疫苗后感染的病例, 48个完全接种后死亡病例 (RIP General Powell), 足够反疫苗的说一阵儿。

    拯救了多少人? 524-48=476 人免于死亡。

    • 反疫苗者从来都是丢掉分母,有一说一,突出效果 +1
    • Your data is for CURRENT, +2
      future data is available if you look at Israel. Canada vaxx program is about 4 months behind Isreal. The first 2nd dose was dispersed in June, and by Dec we should see waves of vaxx infection if Isreal experience would be repeated here.
      • 没错, 我说了啊。有很多局限性。但是已经救了四百多人, 不好吗? +2

        IVM HCQ Azithromycin Zinc 有这个效果?
        • early treatment in US shows 85% reduction of hospitalization, +1

          means it saves more. And your data is for current. I hope I will be proving wrong but if I was right, by Dec we will see waves of vaxx infected, and whatever you "saved" now will be lost later. I sincerely hope vaxx works but I got to face the reality. Israel's data just not go vaxx's way.

          And this is not even counting vaxx injuries.

          Vaxx failed. sooner or later people will realize this. In fact, I bet the rejection of booster will be overwhelming. Time will tell. We won't need to wait long to see it.

          • I, too, sincerely hope IVM/HCQ or any drug could work. IMHO only vaccine is supported by high quality data.
            • yea we all hope the world may come out of this pandemic in good outcome. We differentiate on how. Time will tell. All we can do now is wait and pray. And it won't be long.
        • 跟其他养老院比较一下,光在这个养老院就救了多少老人?感谢网友的转贴,才知道IVM在多伦多一家养老院立下奇功。 -blueskygg(Grass); 10-16 {842} (#14046296@0) +1
    • 你这是只计算短期效应和正面效应,忽略了长期效应和负效应。长期效应目前还不明,但负效应已经有部分可信数据。 +2
      • i am not arguing whether the vaccine works or not.. (I guess I am actually,
        but you wont agree with me:) I am simply saying that the break thru number, which the antivaxxers use to oppose the use of vaccine, is totally expected and shouldn't surprise anyone, if you spent a few minutes to do this back of envelope calculation.
        • 我一直认为疫苗对某些群体(主要是高危人群)是利大于弊,短期保护作用根据已有数据,也是明显的。但是是不是每个人都应该注射(很可能极度加速病毒变种,副作用),甚至被强制注射(更严重的人权问题),才是主要问题。 +5
