Mab developers are picking antibodies that take aim at what scientists call " highly conserved" regions of the virus.

Mab 研发者正在挑选能针对病毒“高度保守”区域的抗体。

Many conserved regions are in the neck, and it's tough to get the immune system to react to the neck.

许多保守区域位于颈部，很难让免疫系统对颈部做出反应。

Going one step beyond that, there may be conserved regions that we could take advantage of across different-but-related virus species— like SARS-CoV-2, MERS, and a few coronaviruses which cause some common colds.

更进一步，可能存在一些保守区域，我们可以在不同但相关的病毒物种中利用这些区域，例如 SARS-CoV-2、MERS 和一些引起一些普通感冒的冠状病毒。

There are key parts of hemagglutinin that haven't changed much over time and are probably critical to infect human cells; these " conserved regions" could be promising targets for universal vaccines.

血凝素的一些关键部分随时间变化不大，可能对感染人体细胞至关重要；这些“保护区”可能成为通用疫苗的有前途的目标。
