I don’t think I have made any conclusions... only observations also, from BBC https://www.bbc.com/news/health-55388846 about the uk mutation Where has it come from? The variant is unusually highly mutated. The most likely explanation is the variant has emerged in a patient with a weakened immune system that was unable to beat the virus. Instead their body became a breeding ground for the virus to mutate.
Will the vaccines work against the new variant? Almost certainly yes, or at least for now. All three leading vaccines develop an immune response against the existing spike, which is why the question comes up. Vaccines train the immune system to attack several different parts of the virus, so even though part of the spike has mutated, the vaccines should still work. "But if we let it add more mutations, then you start worrying," said Prof Gupta. "This virus is potentially on a pathway for vaccine escape, it has taken the first couple of steps towards that." Vaccine escape happens when the virus changes so it dodges the full effect of the vaccine and continues to infect people. This may be the most concerning element of what is happening with the virus. This variant is just the latest to show the virus is continuing to adapt as it infects more and more of us. A presentation by Prof David Robertson, from the University of Glasgow on Friday, concluded: "
The virus will probably be able to generate vaccine escape mutants

有这个可能,但为什么欧美这么处理啊,是不是国内更清楚漏了什么
好早的时候就有美国人传美国军方参与了
疫苗已经很多了,有些根本不必要。 有人为了赚钱也是丧心病狂了。
话说某巨富巨量投资的疫苗是谋划者吗?
被siwang? 这么恐怖

要是真的咋办啊?
我也想知道啊
人类难道要都进化成避世的?
金三胖那里貌似问题不大?
新加坡好像也没有各种乌龙
Mm你是相关专业的嘛
本科的时候念完所有premed需要的课程的
之后对evolution有一点浅浅的认知;mRNA的protection和degradation是研究了有一段时间的
个人觉得 新冠真的是研究bioinformatics的人的天堂
哈哈,你们都好牛
不光是这个P4主任,还有好几个相关领域的人突然死亡
美帝完全就是故意造病毒的,还派了军人投毒,没想到搬起石头砸了自己的脚
活捉五毛一只,回去问你们领导,现在早不说投毒论了好么?
你如果在美国的大学,去问问生物系抓蝙蝠养蝙蝠的,问问他们谁提供的经费去抓蝙蝠,就知道美国自己也脱不了干系。这个事儿美国自己也不想深究(某种程度上)
美帝倒是不至于投毒,应该是研究的时候不小心泄露了。
哈哈,这个有道理
骂中国是因为选举。上次骂墨西哥人WIN了,这次改中国人而已。
