The ECDC classifies B.1.620 as a Variant of Interest.
It has certain mutations that are found in other variants, which have gone on to become Variants of Concern.
Those mutations include E484K, P681H, and S477N, as well as several so- called "deletions" in the virus' spike protein.
The virus uses the spike protein to attach itself to human cells, infect us and spread.
What would make B.1.620 a Variant of Concern (VOC)? "B.1.620 might become a VOC if there's strong evidence to suggest, for instance, an increased transmission advantage, or a change in immune responses [to the virus]," says Dudas.
There is a good chance, then, that B.1.620 will become a VOC.
It is already showing signs of faster transmission — it moves faster, infecting more people, quicker — and that's linked to its ability to " escape" human immune responses. Which is in part because of the mutation known as E484K.
"We can be quite certain that B.1.620 is very likely to be able to evade a lot of neutralizing antibodies that [we have] built up against other strains of the virus that don't have the mutations that this strain has," says Dudas.
The E484K mutation is present in VOCs, such as B.1.351, the South African variant, and P1, the so-called Brazilian variant. It is found in variants detected in the UK, Nigeria, the Philippines, Colombia, Russia, and the US.
"But showing a transmission advantage is extremely difficult. It takes a lot of data and often that's data from countries, where the sequencing data and the medical data can be linked very well," says Dudas.
Getting sequencing data for B.1.620 out of Central Africa, on the other hand, has been difficult.
美国应该也不远了
据说比印度的更难对付。。
据说目前的辉瑞对付不了。
大家早点打booster
要多打早打补丁。。。要不太危险了。

没完没了了啊
是这个视频么？
就这个
大圆脸的视频很及时
估计是个杀老鼠的

同意他这个观点：
大部分国家没有测新型毒株的能力；除了已知的变异，还有未知的变异或许（特别是非洲、印
度境内的）更可怕
目前的辉瑞对付不了，那booster有什么用。

美国药厂的生意啊！连绵不绝，他们以后都不用开发其他新药了，只要不停生产升级疫苗就能养活自己了。难怪美国迟迟不对阿三国禁航呢！只能各种变种进来，药厂不禁有广大y敢on的自愿实验者，还有无限光明的卖疫苗未来。。。。
脸真圆
booster要到9月份才有的打，问题是疫苗的开放跟不上病毒的变异速度的

这变异速度，疫苗真的跟得上吗
