I am concerned about the possibility that the new vaccines aimed at creating immunity against the SARS-CoV-2 spike protein (including the mRNA vaccines of Moderna and Pfizer) have the potential to cause microvascular injury to the brain, heart, liver, and kidneys in a way that does not currently appear to be assessed in safety trials of these potential drugs. Puntmann et al. (JAMA Cardiol. 2020;5:1265-1273) showed that the prospective study of 100 German patients who were recently recovered from COVID-19 revealed significant cardiac involvement on cardiac MRI scans in 78% of them, an average 2-1/2 months after their recovery from the acute illness. Two-thirds of these patients were never hospitalized, and there was ongoing myocardial inflammation in 60%. The abnormalities occurred independent of preexisting conditions, severity of the initial disease, and overall course of the acute illness. Magro et al. showed that there is complement-mediated damage even in grossly normal skin of coronavirus-infected individuals (Human Pathology 2020:106:106-116). They have also shown (Magro et al. Annals of Diagnostic Pathology 2021:50 in press ) that ACE-2 receptor expression is highest in the microvasculature of the brain and subcutaneous fat, and to a lesser degree in the liver, kidney, and heart. They have further demonstrated that the coronavirus replicates almost exclusively in the septal capillary endothelial cells of the lungs and the nasopharynx, and that viral lysis and immune destruction of those cells releases viral capsid proteins (or pseudovirions) that travel through the circulation and bind to ACE2 receptors in these other parts of the body leading to mannan-binding lectin complement pathway activation that not only damages the microvascular endothelium but also induces the production of many pro-inflammatory cytokines. Meinhardt et al. (Nature Neuroscience 2020, in press) show that the spike protein in brain endothelial cells is associated with formation of microthrombi (clots), and like Magro et al. do not find viral RNA in brain endothelium. In other words, viral proteins appear to cause tissue damage without actively replicating virus. Is it possible the spike protein itself causes the tissue damage associated with Covid-19? Nuovo et al (in press) have shown that in 13/13 brains from patients with fatal COVID-19, pseudovirions (spike, envelope, and membrane proteins) without viral RNA are present in the endothelia of cerebral microvessels. Furthermore, tail vein injection of the full length S1 spike subunit in mice led to neurologic signs (increased thirst, stressed behavior) not evident in those injected with the S2 subunit. The S1 subunit localizes to the endothelia of microvessels in the mouse brain, and is a potent neurotoxin. So the spike S1 subunit of SARS-CoV-2 alone is capable of being endocytosed by ACE2 positive endothelia in both human and mouse brain, with a concomitant pauci-cellular microencephalitis that may be the basis for the neurologic complications of COVID-19. The Pfizer/BioNTech vaccine (BNT162b2) is composed of an mRNA that produces a membrane-anchored full-length spike protein. The mouse studies suggest that an untruncated form of the S1 protein like this may cause a microvasculopathy in tissues that express much ACE2 receptor. A truncated form of S1 was much less damaging in mice. While there are pieces to this puzzle that have yet to be worked out, it appears that the viral spike protein that is the target of the major SARS-CoV-2 vaccines is also one of the key agents causing the damage to distant organs that may include the brain, heart, lung, and kidney. Before any of these vaccines are approved for widespread use in humans, it is important to assess in vaccinated subjects the effects of vaccination on the heart (perhaps using cardiac MRI, as Puntmann et al. did). Vaccinated patients could also be tested for distant tissue damage in deltoid area skin biopsies, as employed by Magro et al. As important as it is to quickly arrest the spread of the virus by immunizing the population, it would be vastly worse if hundreds of millions of people were to suffer long-lasting or even permanent damage to their brain or heart microvasculature as a result of failing to appreciate in the short-term an unintended effect of full-length spike protein-based vaccines on these other organs. Particular caution will be required with regard to the potential widespread vaccination of children before there are any real data on the safety or effectiveness of these vaccines in pediatric trials that are only now beginning.
我大概看了下,这位医生担心的是疫苗打到人体里产生的full length/untruncated spike protein有可能造成long-lasting or even permanent damage to people's brain or heart microvasculature. 这个没法预测,17楼的mm说得很在理。假定这位医生的顾虑成立,如果一个人怎么都有感染的风险,要么被病毒感染,有一堆spike protein,要么打疫苗,有一些spike protein,权衡利弊,打疫苗benefits outweigh the risks。如果一个人单身,无娃,可以一直宅家wfh,不用接触社会,那就不用打。

"it appears that the viral spike protein that is the target of the major SARS-CoV-2 vaccines is also one of the key agents causing the damage to distant organs that may include the brain, heart, lung, and kidney" 这是可能的,有血栓症状的可能只是反应特别厉害的,绝大部分人也许有但是至少短期不明显 如果你呆家而且严格戴口罩那可能比打了疫苗到处浪的更安全更负责

这个3-5年的测试时间线有没有一个diminishing value 比如第三年已经95%确定了 第五年也只是增长到96%什么的
在接下来几个月几亿人都会打疫苗 如果没有出现比较明显的副作用 是不是说应该还是有足够的数据支撑疫苗的安全性了?
太搞笑了,你自己的concern 你有任何数据支持了?别人的concern你倒是骂得理直气壮。双标到这么赤果果也是无语。
我有朋友陪婆婆去看牙 自己顺便洗牙 回来全家都中招了 他们很谨慎很谨慎 孩子都没去上学 啥运动也没参加 小心谨慎了一年多 看牙把全家都感染了 当然也都康复了现在 但是那两周的心理折磨也够受的
自己没琢磨就跟风打了 起码不具备指责别人不打的资质
我这一年来wfh, 每周都去超市买菜,戴手套戴口罩,回家好好洗手。懒得做饭的时候就外卖,包装扔掉,饭菜用微波炉转一下。周末开车出去爬山看海。原来经常一起约饭打牌的几家朋友现在网上攒牌局。我不觉得这样就会感染。很多人觉得不打疫苗就是感染,只有两个选择,我不觉得是这样

不管如何 搞清楚原理是没错的
seems to be key
做过免疫研究的人回答你: 没法打消你的concern。 因为这个疫苗研发的时间线,根本不可能保证它有跟我们常用的其他疫苗一样充分的临床测试/跟踪观察时间(通常至少3-5年) 现在新冠疫苗的状态相当于你去买车,问dealer这车的安全测试结果如何,dealer说”哦我们安全测试正做着,结果还没出来,但是已经有很多人开上了目前为止大部分还没事。”
至于有人举出自己药厂医院的同事都打了之类之类,我只能说每个人收集整合信息的方式不一样,判断方式也不一样。 自己独立思考判断吧。
yeah
像lz quote的那位医生这样大胆畅言且心细的医生再多一点就好了
但就如我们日常所见 大多数人也就是一工作而已
生死有命
打疫苗是为自己,不用看得多伟大,也别指望别人打了会保护自己,得想明白这个
+1
看了好多医生说outdoor transmission几乎不存在,有没有医院的人说说,走在路上会不会被传染
如果去年都没被感染 保持那个作息习惯感觉不危险
我去年年初就被小孩从学校带回病毒感染了 但奇怪的是我同事们都没被我传到 所以其实做好防护应该还行
我不是大牛,但是是疫苗派,简单回复一下这个医生的concern: 1)感染引起的严重患者会有cytokine storm,这个会导致免疫系统攻击自身组织。这能解释一些器官组织没有病毒RNA但是有损伤的现象。所以源头是新冠感染后不受控的过度免疫反应。而新冠疫苗造成的免疫反应,相对新冠感染还是很可控的。大部分人打疫苗后的反应是2天之内消失或者缓解。 2)那个老鼠实验是注射刺突蛋白到尾部血管,自然刺突蛋白会随着血液流向全身。哪儿ACE2受体多就容易在哪儿富集。但是富集并不代表有毒性。观察到的老鼠的行为学变化比如口渴,有胁迫反应要不然太主观,要不然是很难跟神经系统的变化联系上。另外我也没看文章不知道多少蛋白量注射给老鼠。离开剂量谈反应都是耍流氓。 3) mRNA疫苗打进的是肌肉组织,理论上是在local肌肉组织合成刺突蛋白后,刺突蛋白被递承给免疫细胞刺激免疫反应,而mRNA快速降解。这个过程应该刺突蛋白扩散到脑部的可能性不高,就算有,数量也不多。
这个医生最大的担心来源是把新冠病毒感染产生的免疫反应和mRNA疫苗产生的刺突蛋白产生的免疫反应划等号。目前没有证据支持这种担心。
可以找找看有没有同样genetic background的人 打了结果如何
对未来很绝望啊😭
作为一个外行,我感觉如果感染了病毒的话,spike protein应该比疫苗只多不少吧?
三样都有,周四打完m第二针。反应比我lg大,他全身酸痛了一天半,基本没发烧。我打完当天晚上发烧到102,今天中午才退得差不多了。
说得太好了,尤其最后一段。感觉很多做题家一路过来除了会做题,科学思维根本没形成
波士顿附近大家打疫苗的热情是很高,最近不管网上还是见面,中国人社区或以外,最热门的话题就是交流哪里/怎么能刷到疫苗。好多家里有(满16岁)高中生的,都第一时间带着娃去打了。
"it appears that the viral spike protein that is the target of the major SARS-CoV-2 vaccines is also one of the key agents causing the damage to distant organs that may include the brain, heart, lung, and kidney"
这是可能的,有血栓症状的可能只是反应特别厉害的,绝大部分人也许有但是至少短期不明显 如果你呆家而且严格戴口罩那可能比打了疫苗到处浪的更安全更负责
我一排上就打了,现在才打了一针,还是小心宅着。我们明确今年年底前wfh,以后公司也倾向于engineering的职位能wfh的就多wfh,我也不打算疫情结束前旅游或者外食,我还是去打了,我算比较胆小的。我老公去年底那轮爆发前做了个小门诊手术,之前的检查连手术,做了两次视频外加三次office visit,紧张了好几天,我是去年所有的年检全都skip了,一年半没洗牙了。认真说,即使不去公司不旅游,也不可能一直这样躲着的,总有些事情必须跟人接触还得摘口罩。
我糖尿病,曾经得过荨麻疹,我老公高血压,我们打完两针了。疫苗选的p家的。打了第一针后,我打针处红肿痒痛了三四天,消了,打针后一周又开始红肿痒痛了三四天。我老公第一针后没反应。打了第二针后,我当天晚上开始发冷头晕没精神食欲降低。cdc上提到的典型副作用我全有。昨天在家躺了一天,中间勤起来走动一下和喝水。今天已经感觉完全恢复正常,除了手臂抬起来时有些酸。我老公是打第二针后的早上手臂酸,没其他副作用。
Same here, just got my 1st dose today. cannot be a recluse so have to take the one with potentially less risk.
完全同意你的观点。我也是这么觉得。总不能保证完全不生病。总是要和社会接触的。
是啊我family doctor自己生病cancel我的appointment我怀疑她得新馆了。 我打算去医院就带N95。打了疫苗也不能保证不被传染。还是带好口罩手套。
别的不说,你引得这篇什么都没说。你读过就知道他引用了一篇文章说感染病毒的人会有cardio 有关的问题。注意文章说的是感染病毒后的人群。下段作者说的他怀疑是spike 蛋白引起这些问题,但没能举出任何已发表文章来support这个观点。所以总结起来就是有人说感染病毒会有心血管问题,所以我怀疑疫苗会引起这些问题。你觉得这个逻辑靠谱就行,反正他这要是篇paper的话,肯定被editor骂死。
科普的太好了。早知道你给科普了我就不费劲了。
确实是。我们小镇做题家只看到周围这些做研究发paper一辈子的各种PhD和MD打了就兴奋的不行,哪有你们过去这一年全文阅读各种paper临床数据后给我们科普来的靠谱啊。
别提这些博士医生了,没看之前有MM说我们这种相信这些博士医生的人是小镇做题家么。她大概没意识到这些疫苗临床数据都是这些小镇做题家研究出来的。希望她以后千万什么药和疫苗都别用,别让我们这些小镇做题家害了她。

所以你觉得作者担心的对大脑,心脏,肝脏和肾的损伤这些已经be assessed in safety trials of these potential drugs了并且有了明确的结果了是吗?
我自己全家除了孩子都打了,因为要出门上班,家里还有老人,孩子要出门上学。但是,如果我可以全家在家上班孩子在家上学,平时也不和别人聚会那完全不需要打。
这病毒变异的趋势并不像以前的全球大流行,没有减缓,反而像不停在找突破。减少感染也就减少变异概率。
宅家太久了,不利于心理健康。
副作用有,所以对青少年要谨慎,起码等到明年再看成年人的数据统计。现在的变异种株的致病旅致死率在上升,所以成年人排到就打。
这些看看就好,他自己没有实验数据支持,也没有别人的研究支持。
这么多专业研究你不看,非要相信一个八杆子打不着的儿医,让我科普都无从做起。这么简单说吧,他说的这话基本就跟吃米多了会砷中毒一样。你说他说的不对吧,你也没做过实验证明对不?但你会因为这个不吃米么?所以说民科的力量就在于它可以不负责任乱说,说完也不负责,但研究人员不可以,没有实验数据在手不能出结论。所以民科一张嘴,科学累断腿。可惜宣传民科的都觉得自己真理在手,所向披靡。
那你这种专业人员给我们科普一下专业研究吧?就像前面举例子汽车的安全测试一样,这个安全测试做完了吗?有明确的结果了吗?短期和长期的副作用有哪些?带有什么样的基因的人会出现什么类型的副作用?那些出现例假问题,面瘫问题,肿块问题的等等是由于什么原因引起的?尤其是长期的副作用,有明确的结果说明一定没有了吗?
短期安全测试当然做完了,phase 1,2,3 data都有,包括有效性安全性不然Fda 怎么批准的 长期确实还没有数据,研发出来才一年
fda并没有正式批准啊,只是批准了紧急使用
夸张。
只是紧急使用
安全性和副作用79楼MM直接回答了。至于你说的面瘫例假什么的没研究过,除非有证据表明这些情况在打过疫苗的人群里明显上升,但我怀疑你只是道听途说,没有数据支持。基因问题需要更多时间,因为基因太多,不可能每个都研究。一般只能研究疑似相关基因。而基因问题由于在信号通路里的作用非常复杂,一般要很多年才能确定机理。简单来说就是基本不可能等到什么机理都研究透了再打疫苗。也没有疫苗是什么机理都研究完了才开打的。这么说你明白了么?
不不不,这个病毒不知道到什么时候。你不能保证三五年不出门,不和人接触能受的了
79楼那人貌似连fda是不是正式批准都没搞清楚,还有她回答了什么安全性和副作用?
你的回答我也看明白了: ----安全测试?没做完 ----明确的结果?没有 ----短期和长期的副作用?不清楚 ----基因问题?没研究透 。。。。。。。。
你列这些问题,没有哪个国家的疫苗可以给你满意的答案,现实就是这样。 你是想说服自己不打,还是说服别人不打?
你真的读了79楼MM的回答了么?还是你不明白FDA approve的标准?短期安全性做完了,没做完不可能批。没有做完长期安全性,因为时间不够。副作用你指的是面瘫这种么?跟你说过了,除非有证据显示正相关才会做啊,不然打一万个人有一个碰巧面瘫了,就是打疫苗的问题了?学过统计概率没?还是你觉得不打疫苗的人一定不会面瘫? 跟你说过了,基因问题就是要很多年,如果有基因问题显示正相关的话。这么多年癌症不能完全治愈是一样的道理。again,没有规定要求把基因都研究完了才能打疫苗,因为理论上不可能。你打过所有的疫苗都不能保证这一点。
那请问你明白fda正式批准和批准紧急使用权的区别吗?长期安全性一系列问题不知道不明白的情况下你为什么觉得别人有concern就不行?
哇,这么多反问,明显有情绪啊,我又没跟你说过话
我只是说我自己目前的concern, 我为什么要去说服别人?现在是一个自称是内行的专家在给我科普,我在洗耳恭听
啊我以为我回的是那个果子I D,误伤MM不好意思。
那个医生说的就是建议再积累足够多的数据证明他的这些担忧问题都不是问题之后才好安全普及疫苗,你可以像楼上一位那样用科学论据反驳他说的这些问题不是问题,但你没完没了的说那个医生是民科却又没有任何科学的论据,号称你懂生物学,可是科普你也不做就开口喷,有意义嘛? 楼上说的小镇做题家还真就是你这样的
这个MM说的靠谱。不过当时非典是早就已知大量激素会造成股骨头坏死的还是决定使用,并不是事先没有assess安全性。
