Breaking News: A new, two-dose Covid vaccine, made by the Europe-based pharmaceutical companies Sanofi and GSK, showed 100% efficacy against severe disease, and may be an effective booster for other shots, its makers said. https://t.co/dn37sIGYyT — The New York Times (@nytimes) February 23, 2022
The duo said data from a trial shows that two doses of the Sanofi-GSK vaccine have 100% efficacy against severe Covid-19 and hospitalizations and 58% efficacy against any symptomatic Covid-19 disease. They said the safety of the vaccine was favorable too. The firms are hoping to catch up with rivals after falling far behind in the race to develop Covid-19 shots. Their product was delayed by an early dosing error during trials, initially disappointing results in older people and other issues. It will be available as a two-dose vaccine and as a booster. It relies on a conventional protein-based approach, compared with the newer mRNA technology used by Pfizer/BioNTech and Moderna, which makes it easier to store and transport.

德国 法国 美国 瑞士的生物化学都不错啊
法国的数学甚至比美国都厉害
德国工程科学 比美国也厉害啊
不是mrna
我是被这次毒疫苗还强制,搞的对传统疫苗都有点儿失去trust 了。暂时观望一下,小白鼠们上吧。
吹牛来的,大概是一辈子没做过实验的人写的报道。
我觉得对大部分人来说更有价值的是他们的booster trial,抗体数据显示和mrna疫苗的第三针类似,中和滴度有几十倍的提高,可惜没看到对各个变种的中和水平的实验结果。在我们的免疫系统接触过几次细胞内抗原(mRNA疫苗,腺病毒疫苗,或者真实感染)以后,正确的免疫记忆已经形成,再打新的针只是用一点抗原去刺激记忆B细胞再分化一下,分泌一些抗体,这个时候booster用细胞内抗原还是细胞外抗原的影响并不是那么大。一个比较极端的例子是流感疫苗,免疫系统都已经不知道见过多少遍了,结果mRNA疫苗的效果和无佐剂的灭活疫苗差不多。如果已经打过两针mRNA疫苗,并且已经知道自己对mRNA疫苗反应很大(比如持续很久的头疼头晕心悸什么的),但是又有各种高危因素需要疫苗的保护,那么重组蛋白疫苗是个很好的选择。

因为case很少啊,安慰剂组第一针后10个severe case,第二针后4个,疫苗组没有重症。不要过分解读这种“保护能力100%”
现在疫苗就是靠吹,lol
法国人真的爱研究,认识的几个法国籍的工程师,业余爱好都是数学。
请教一事。丽珠生物疫苗用铝佐剂,细胞免疫会不会很差?
同意✅
好巧 我也是因为这次新冠疫苗现在开始一个一个研究给娃打的传统疫苗了 以前都从没怀疑反思过
效果好像比Novavax差一些。目前还没有订单?
