Although deaths after COVID-19 vaccination have been reported to the Vaccine Adverse Events Reporting System, few studies have been conducted to evaluate mortality not associated with COVID-19 among vaccinated and unvaccinated groups.
What is added by this report?
During December 2020–July 2021, COVID-19 vaccine recipients had lower rates of non–COVID-19 mortality than did unvaccinated persons after adjusting for age, sex, race and ethnicity, and study site.
What are the implications for public health practice?
There is no increased risk for mortality among COVID-19 vaccine recipients. This finding reinforces the safety profile of currently approved COVID-19 vaccines in the United States. All persons aged ≥12 years should receive a COVID-19 vaccine.
CDC和几家医疗系统合作进行的一项大规模的研究报告，在去年10月29日发表。这项研究统计了2020年12月14日到2021年7月31日的时间段，包含了注射疫苗的640万人和没有注射疫苗的460万人，统计的是在这个时间段里，死亡30天之内没有新冠确诊的案例，也就是非新冠死亡的案例。
因而这个不是疫苗有效性的研究，它与Delta，Omicron之类的变异更是没有关系。这是有关疫苗安全性的研究。

统计结果，在这个表格里：
举个例子，我解释一下画圈的数字的表达的信息：
在45-64的年龄段，
在打过一针Pfizer疫苗的人里，有0.16人年在30天之内出现非新冠死亡；
在打过两针Pfizer疫苗的人里，有0.13人年在30天之内出现非新冠死亡；
在打过一针Moderna疫苗的人里，有0.16人年在30天之内出现非新冠死亡；
在打过两针Moderna疫苗的人里，有0.17人年在30天之内出现非新冠死亡；
在没有打过疫苗的对照组里，有0.51人年在30天之内出现非新冠死亡。
（补充：上面的数字是每100人年的死亡数字）
为什么数据是这样，每个人都有不同的解释。
我这里只有数据，数据是客观的。至于如何解读这个数据，就很难避免掺杂个人的立场和观点了。
不信的还是不信。
我只给数据，不管解释原因。
扔个炸弹就跑。
这个统计数据有关疫苗的安全性。
只是能让大家知道疫苗后30天内死亡的概率比其他因素死亡的概率还低。
这个担心很大程度上是由于对事情的机理不太清楚。
据观察，反疫苗的大多除了情绪化讥讽谩骂，貌似也提不出更多实质理性东东，那种愤怒怨恨不仅限于针对疫苗，而是对科学和医学形成的负面/抵触/不信任/曾被“伤害”过，借疫苗来发泄私愤而已，跟“医闹”差不多：）。摆证据说理，主要对中间犹豫摇摆人群或许有用。
