Now, just--what this diagram also shows you is that that response is specific to that particular antigen.

看,就像这幅图表展示的一样,免疫应答是针对特定的抗原

One of the things that happens is that certain cells within your body process the vaccine or the antigen and we talked about that.

在人体内,发生的反应之一是,特定的细胞对疫苗或者抗原做出反应,之前我们讨论过这个

Make a lot of the virus, it has all of its antigenic epitopes on it, but we'll just kill it so that it can't replicate.

先增殖出大量的病毒,病毒表面有特定的抗原决定簇,然后杀死病毒使其无法复制

When you get exposed to that particular antigen they say, 'I'm on, it's my time'.

等到你暴露在特定的抗原中,它们说,该我了,到我大显身手的时候了

One of the things that I didn't mention before is that when you get this primary response and then the secondary response, if you looked at the antibodies that are generated during the primary response, again we're only looking at antibodies that bind to the particular antigen or vaccine that we have used for the priming.

还有一点我之前没有提及,当你获得初次免疫,以及再次免疫之后,如果你仔细观察抗体,观察那些在初次免疫中生成的抗体,这次我们同样只是观察抗体,那些与我们在初次免疫中所用到的,特定抗原或疫苗相结合的抗体

In this case here, you're generating host cells, cytotoxic T-cells, that can kill only very specific cells, cells that are expressing this foreign antigen.

而在这个例子中,人产生宿主细胞,即细胞毒性T细胞,它只会消灭特定的细胞,也就是携带特定异己抗原的细胞
