我们产生的多数抗体是与病毒表面蛋白血凝素的球状头部结合的。

Most of the antibodies we produce bind to the globular heads of a surface protein on the virus called haemagglutinin.

然而，结合效率在不同毒株间存在差异，而且这种差异部分决定于血凝素蛋白中的受体结合位点。

However, binding efficiency varies between flu strains, and that variation is partly determined by the receptor-binding site (RBS) within the hemagglutinin protein.

报道还指出，EB治疗是通过与流感病毒血凝素结合，抑制病毒复制，从而阻止了流感病毒与细胞的黏附。

Eb treatment inhibited viral replication by binding to influenza virus hemagglutinin, thereby preventing attachment of influenza virus to cells, the report indicates.
