#交差免疫:Cross-immunity

従来のコロナウイルス感染した記憶が働いて、新型コロナの重症化を防いでいる可能性があるらしい。
 
交差免疫」と呼ばれるものらしいが、免疫の働きはより研究を進めて、明らかにしてほしいです。

It seems that the memory of the conventional coronavirus infection may be working to prevent the new corona from becoming more severe.

It seems to be called "cross-immunity", but I would like you to further study and clarify the function of immunity.
