水際作戦の強化を


The variant, which descends from the B.1.1 lineage, has an “incredibly high” number of mutations, experts say, with fears that it is highly transmissible and effective at evading the body’s immune response.

B.1.1529 has 32 mutations located in its spike protein. These include E484A, K417N and N440K, which are associated with helping the virus to escape detection from antibodies.

Another mutation, N501Y, which is found in the spike protein, appears to increase the ability of the virus to gain entry to our cells, making it more transmissible.




“It will take a few weeks for us to understand what impact this variant has on any potential vaccines,” Van Kerkhove added.

Any new variant that is able to evade vaccines or spread faster than the now-dominant Delta variant might pose a significant threat as the world emerges from the pandemic.

mutations の回数が多いとかなんちゃら、の含意がわからなかったが、感染力がつよくで、抗体を回避しやすく、いままでのワクチンが効くかどうかは、まだ、不明なんだね。
