Blood clots as prevalent with Pfizer and Moderna vaccine as with AstraZeneca's: study Published: April 15, 2021 at 6:05 a.m. ET By Steve Goldstein marketwatch.com
A study by Oxford University found the number of people who receive blood clots after getting vaccinated with a coronavirus vaccine are about the same for those who get Pfizer and Moderna vaccines as they are for the AstraZeneca vaccine that was produced with the university's help. According to the study, 4 in 1 million people experience cerebral venous thrombosis after getting the Pfizer or Moderna vaccine, versus 5 in 1 million people for the AstraZeneca vaccine. The risk of getting CVT is much higher for those who get COVID-19 -- 39 in a million patients -- than it is for those for get vaccinated. AstraZeneca's vaccine use has been halted or limited in many countries on blood clot concerns.

注意最后一段话:新冠本身引起血栓和新冠疫苗引起血栓的机制是否一致尚不清楚。

英国的研究明显是在为自己的疫苗鸣不平,辉瑞和莫德纳同样引起血栓但美国却单方面强调阿斯利康的风险。
辉瑞和莫德纳疑似引发血栓的副作用病例有多少?有人知道吗?
根据这个措辞,有可能存在一些引发不严重的血栓的病例
这涉及到概率问题:得新冠的概率
对不同国度地区人种,得新冠的概率不同;
AZ或 JnJ的血栓。
AZ和 JnJ的血栓同时伴随血小板骤降,非常罕见,不能用平时治血栓的肝素,否则有生命危险

一切都在预料之中。

发现疫苗后血栓不要用肝素,要查 PF4和血小板, 如果阳性用其他药物治血栓
是这么说的 (看下面小字)。
Thrombosis在一般人群也有,但是伴随 thrombocytopenia才是为什么暂停 Janssen的原因。这个slide deck 后面也解释了
