意大利国立健康/卫生研究院(ISS)最近出了一份报告，详情见网页：

https://www.epicentro.iss.it/en/coronavirus/sars-cov-2-analysis-of-deaths

有英文版的 pdf 文件：

Report in English “Characteristics of COVID-19 patients dying in Italy Report based on available data on 5th October, 2021” (pdf 166 kb).

报告中有一个表

Table 3. Clinical characteristics observed in SARS-COV-2 positive deceased patients ‘unvaccinated-no dose’, ‘vaccinated with early contagion’ and with ‘full vaccination course’

很有意思。表格比较了三组Covid-19患者的平均死亡年龄。

group 1. Unvaccinated：

78.3

group 2. Vaccinated with early contagion (Diagnosis <= 14 days from the 1st dose or unique dose):

83.9

group 3. Full vaccination course (Diagnosis > 14 days from the 2nd dose or unique dose):

85.5

还给出了标准差和p检验值。

报告说，数据只是用来描述用，而不是为了得出什么结论。
