First of all, it's  probably not engineerable, and second of all, I don't believe that for a moment.

首先，它可能无法工程化，其次，我暂时不相信这一点。

And if you attach viral proteins to it, like this, you'd have something that looks, to an immune system, like a virus— but would be completely harmless and very engineerable.

如果你将病毒蛋白附加到它上面，就像这样，你就会得到一种在免疫系统看来像病毒的东西——但它是完全无害的，而且非常可工程化。
