看到这个信息,能回答大家关于中国一个疫苗的疑问。 看来有一部分是给essential worker紧急批准使用的,同时三期在进行中 The private Chinese company Sinovac Biotech is testing an inactivated vaccine called CoronaVac. In June the company announced that Phase 1/2 trials on 743 volunteers found no severe adverse effects and produced an immune response. Sinovac then launched a Phase 3 trial in Brazil in July and another in Indonesia the following month. Reuters reported that the Chinese government gave the Sinovac vaccine an emergency approval for limited use in July. Meanwhile, Sinovac has been preparing to manufacture the vaccine, reaching an agreement to supply Indonesia with at least 40 million doses by March 2021. https://www.nytimes.com/interactive/2020/science/coronavirus-vaccine-tracker.html
“But I defend the CDC in their effort to try to be sure people are prepared,” Collins said in an interview with CNN.
然後NIH就出來打臉了: The director of the National Institutes for Health, Dr. Francis Collins, said it’s “unlikely” that a coronavirus vaccine will be ready by October.
The US Centers for Disease Control and Prevention has told public health officials around the United States to prepare to distribute a potential coronavirus vaccine as soon as late October. It’s also provided planning scenarios to help states prepare. “This is like the Boy Scout motto, ‘Be Prepared,’” Collins said. “Even if it''s very low likelihood, if everything happened to come together really beautifully and we had an answer by then and we knew we had a vaccine that was safe and effective, wouldn''t you want people to be ready to figure out how to do the distribution? That''s all that CDC is saying.” “Now keep in mind that the likelihood of that is pretty low,” Collins added. There are currently three vaccines in the US in phase 3 clinical trials.

阿斯利康的疫苗在英国的三期临床应该快出结果了啊,估计就是九月底十月初的事情。如果结果好的话美国给个EUA当然没问题。
美国自己的三期临床有可能会在结束之前,比如10月底,就看到统计上显著的有效性信号,这个时候给个EUA也是有可能的,但是显然争议会更大一点。
然后还有一个gray zone,就是很多国家现在这么高的感染率,几千人的二期临床甚至都有可能看到统计上显著的有效性证据。比如novavax在南非做的二期有2600多人,而判断疫苗是否有效只要志愿者中有150-200人被感染就足够了。这个时候不排除川普施压让FDA给EUA的可能性。
如果连一点有效性的证据都没有,拿着抗体数据就让疫苗上市了,万一出点什么问题比如产生了ADE,结果打了疫苗的人再接触病毒以后直接呼吸衰竭挂了,那所有经手的人都是要上历史耻辱柱的。就算川普有这个想法,我觉得FDA也不敢去背这个天大的锅。
让美国人承担这个风险的
Re 这么仓促批下来的疫苗,又是这个敏感的时间段。
还是先看看吧。
灭活疫苗很危险的,现在大多数公司都不开发灭活了
这是好消息啊, 美国加油!
理论上都要三期,特别是新冠这种可能有ADE的病毒,没有大规模三期临床谁也不知道打完疫苗再接触病毒的人会不会直接呼吸衰竭挂掉。只不过实际上不是所有国家都愿意老老实实等结果。
直接上了,现在好像降到200 多人刀,同学群做医生的有在推销
你说反了吧, 灭活的危险, 那活疫苗更安全?
难道新冠有活病毒疫苗?
你没搞懂什么叫灭活疫苗,这个是指把病毒杀死然后注射到人体来诱发免疫反应的疫苗
说他危险是因为如果杀死的不完全,就是把病毒直接注射到人体内;本来好好的没生病....
实际上应该是不存在什么活疫苗
减毒活疫苗也有的,流感喷鼻的疫苗就有过减毒活疫苗。新冠没看到做这个的。做灭活的我也只看到一个。
后遗症不会几天内出现
疫苗有没有效果,安全不安全,做完三期就应该比较清楚了。如果有任何安全隐患,制药公司绝对不会去投产,连新的试验都会很谨慎。
当然,我是说位于美国,欧洲的有信誉的大公司。如果有一粒严重不良反应,被证明是疫苗引起的,试验马上会终止的。如果他不这样做,那么trial proposal 根本不会批准。
太好了。好事情。
他们已经接种几个星期了 我很佩服他们的勇气 我们是essential worker 接触的人去的地方非常广 参与实验再合适不过 至于我们这些旁观者不参与也是祝福 而不是打嘴炮 你有选择不打的权利
那中国的疫苗呢 也没听说第三期 已经开始打了

翻到最下面还是有几个在做的,比如印度。。。
只要对川皇上台有利,他才不管呢,他会逼迫FDA就犯,就如他逼迫美联储CDCNIH,他自己七老八十没几年可活,那管别人的疫苗问题,他再次登基比美国人民的人命更重要。
感谢你的同事们。
这几年美国毁掉信用和权威的不仅仅是CDC.
前面的好像也是以招志愿者的方式,也就是属于试验阶段
中国的三期疫苗早就出新闻了,在别的国家做。等结果种

以前(70年代?)美国出了大流感以为西班牙流感重现,政府组织全国打疫苗,出了很多guillain barre 综合症的
然後NIH就出來打臉了:
The director of the National Institutes for Health, Dr. Francis Collins, said it’s “unlikely” that a coronavirus vaccine will be ready by October.
The US Centers for Disease Control and Prevention has told public health officials around the United States to prepare to distribute a potential coronavirus vaccine as soon as late October. It’s also provided planning scenarios to help states prepare.

我也跟我太太說,做好我們要贏樂透的準備。
祝福新疫苗顺利靠谱
我国内的朋友也在微信上搞笑这个疫苗。
不相信的不打就是了
中国的三期疫苗很多高危职业的几个月前就已经打了,是三期实验的一部分。
是哪个疫苗?
我同学北京某医院急诊科,一个多月前单位就号召打新冠疫苗,可没告诉是临床三期实验。微信群里有不少人说亲友出国工作的,必须打了疫苗才能出。注意打得时候可没告诉你这是三期实验。国内有几个疫苗都在国外做三期呢,没等数据出来,就给老百姓用了,这就是墙国!
张口就来。。。疫苗最大的风险是没有效果,而不是得病,更何况病毒本身的致死率在3%左右。
流感本来就可能引起格林巴利症,你这些例子并不能证明就是疫苗的作用。
这个历史的耻辱柱关系不大。这种大规模的施打就算Trump要硬推,生产公司自己都是会极力反对的。美国有多少家药厂因为官司倒闭了?这可不是开玩笑的。。。
他们打的是Pfizer 还有一个同事的brother在 astrazeneca也开始第三期了 说目前一切顺利 可以在clinicaltrials.gov登记参与实验 我同事去打时看到有不同年龄段参加的 有60+ 被选中的工作性质都是面对大众接触的人 去的地方多 容易感染的人
更新一下 他们打的是Pfizer 还有一个同事的brother在 astrazeneca也开始第三期了 说目前一切顺利 可以在clinicaltrials.gov登记参与实验 我同事去打时看到有不同年龄段参加的 有60+ 被选中的工作性质都是面对大众接触的人 或者是essential worker 所以很合适 这个时间点也是刚好而已
为了选举,拖延疫苗上市,要死多少人,你明白吗?🐖党为了选举,不惜牺牲人民,是有目共睹的。
我觉得打不上,我朋友报名三期modera家的志愿者也排到十一月啊。十月底哪能那么快
