COVID-19 疫苗会引起血栓吗?

在多项研究中,Moderna 或 Pfizer-BioNTech mRNA 疫苗并未显示会增加血栓风险。然而,两种 COVID-19 疫苗与一种极为罕见的综合征有关,这种综合征被称为疫苗诱发的血栓性血小板减少症(VITT)。它于 2021 年 3 月被发现与阿斯利康 COVID-19 疫苗有关,后来又与强生 COVID-19 疫苗有关。在极少数情况下(百万分之 2 到 20)身体产生的抗体作为疫苗的副作用会导致血小板不受控制地激活。这会导致血小板计数低和血块形成。

这种罕见抗体的出现是一个随机事件,与一个人的病史或任何特定条件没有已知关联。“无法预测谁可能会产生触发 VITT 的罕见抗体,”Abou-Ismail 说。“虽然与其他人群相比,它在年轻女性中更为常见,但即使在该群体中也极为罕见。”

Do COVID-19 vaccines cause blood clots?

The Moderna or Pfizer-BioNTech mRNA vaccines have not been shown to increase the risk of blood clots in multiple studies. However, two COVID-19 vaccines are associated with an extremely rare syndrome known as vaccine-induced thrombotic thrombocytopenia (VITT). It was discovered in March 2021 in connection to the AstraZeneca COVID-19 vaccine and then later with the Johnson & Johnson COVID-19 vaccine. In rare cases—2 to 20 per million—antibodies that the body produces as a side effect of the vaccine lead to uncontrolled activation of platelets. This causes both low platelet counts and blood clots to form.

The occurrence of this rare antibody is a random event without a known association with a person’s medical history or any particular conditions. “There’s no way to predict who’s likely to develop the rare antibody that triggers VITT,” Abou-Ismail says. “While it is a little more common in younger women compared to other populations, it remains exceedingly rare even in that group.”

  • 枫下家园 / 医药保健 / 犹他大学医院官网发表文章说几个研究都没有展现mRNA疫苗会增加血栓危险,但是疫情早期发现covid和“住院”病人之间有联系。相信科学的可以去看看。
    Blood clotting is a well-recognized complication of SARS-CoV-2 infection. U of U Health hematologist, Yazan Abou-Ismail, MD, answers questions about the association of blood clots with COVID-19 and certain vaccines.
    • 你怎么读书滴?开头就说血栓是已经证实的疫苗副作用。 +4
      • 你怎么读书的。开头写的血栓和covid的关系
        • 开头标题明明是:BLOOD CLOTTING, COVID-19 AND VACCINES三角恋嘛。 +2
          • 仔细读:The Moderna or Pfizer-BioNTech mRNA vaccines have not been shown to increase the risk of blood clots in multiple studies.
            • 对呀,没有increae the risk, 但是还是有原始的risk,只是没有提高而已嘛。感染50%血栓风险,打疫苗50%血栓风险,这叫风险没提高,但是打了疫苗又感染了病毒,那岂不是风险加倍?好吓人哦。 +4
              • 都告诉你没提高了,还琢磨加倍啥啊。回炉学校好好练练 +1
              • 可不可以这样理解?have not been shown,可能有危险,也可能没危险,总之没有显示出来。就象你很有钱,但没有show出来,咱也不能因此说你穷啊。
        • 赶紧看了一眼,我一逻辑哈,感觉德国尸检大师切开血管看见的,新冠导致血栓,如果血管堆积多的就堵死了,年轻的新冠帮助堆积所以以后看得见的各种血栓病会比新冠之前多,同理疫苗也有小小血栓作用但是比新冠引起的小(因为疫苗是要造成类似新冠的反应) +1
          课代表发文要给个中心思想比较好😊
          • 我觉得原文说得已经挺清楚的了:The Moderna or Pfizer-BioNTech mRNA vaccines have not been shown to increase the risk of blood clots in multiple studies. mRNA疫苗不会增加血栓风险。

    • ....individuals are at a significantly higher risk of developing a blood clot from COVID-19 infection than following COVID-19 vaccination.
      • 那打了疫苗又得了新冠,那岂不是double higher risk? 因为疫苗不防infection呀?哈哈 +2
        • 这个就属于尴尬而不失礼貌的笑。 +1
          • 你看,引用的结论,居然自相矛盾,这就是你们奉若神明的“权威”。 +2
            • 你开心就好啊。 +1
              • 你看,一到严谨的逻辑分析,你们就环顾左右而言它了。完全经不起推敲嘛。 +2
                • 有什么可以推敲的,白纸黑字写得那么清楚你都能胡搅蛮缠,还有讨论的必要吗? +2

                  individuals are at a significantly higher risk of developing a blood clot from COVID-19 infection than following COVID-19 vaccination.
                  • 打了疫苗又感染了结果呢?这个现象很普遍呀? +2
                    • 你们通过新闻里描述的病情远程诊断就可以。 +1
                      • 你引用的这句话,仅仅适用于打了疫苗,可以防感染,才有意义。因为不感染,就可以极大降低血栓风险。可现在不是这样,官方都说:疫苗不防传染。那么血栓风险加倍。 +5
                        • 【风险加倍】,是说打了疫苗比不打疫苗得血栓的风险加倍吗?楼顶文章里有数字,你可以用这些数字给我个推导过程吗?
                          • 你引用的那句话就是这个结论嘛,不用推导,事实也证明如此,加拿大接种疫苗后新冠重症住院人数比例,高于疫苗接种比例,加拿大官方数据显示,住院重症病人绝大多数是接种疫苗的。 +1
                            • 【与接种疫苗相比,个体因感染新冠而形成血栓的风险要高得多】。这句话可以推出【打了疫苗,血栓风险加倍】这样的结论?那我可能确实是老糊涂了。
                              • 这句话的意思是:接种疫苗会有血栓风险,但是比感染新冠后形成血栓风险要低。我请问你:接种疫苗后,又感染了新冠而发病,难道不是这两种风险叠加吗? +1
      • 门外汉我一直这样感觉,得新冠时一定要吃肠溶阿司匹林,打疫苗时也要吃
    • 没有发现危险,又不是发现没有危险。略过。
