Memory cells are long lasting cells that remember this exposure and can respond very quickly on second exposure.

记忆细胞可以长时间记忆与抗原的接触,并在再次免疫中迅速做出应答

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

It's not just that your whole immune system gets revved up and it's going to respond more rapidly to any antigen it's exposed to.

并不是整个免疫系统都得以加强,免疫应答会对,以前接触过的抗原做出的应答更加迅速

The response to the second exposure in antigen is different in a couple of ways.

第二次接触相同抗原,免疫系统的应答,在以下几个方面是不同的

That shouldn't be too surprising given what we talked about last week, that your immune system, the adaptive immune system in particular, responds to individual antigens differently.

你们不必惊讶,上周我们讲过免疫系统,特别是适应性免疫系统,对不同抗原的应答是具有特异性的

The other part of the adaptive immune system is the cell mediated immune system and this is an immune where that doesn't involve antibodies but involves cells that are activated in response to a foreign antigen and that utilize cellular means to get rid of it.

获得性免疫系统还包括,细胞免疫,这一免疫反应不包含抗体,但包含可以被激活来应答,并清除外源抗原的免疫细胞

If we did the experiment where on this booster we included not only the initial antigen but some unrelated antigen, the response to the unrelated antigen called B here, looks like a primary response.

如果实验中我们使用的后续疫苗,不仅包括原抗原,还包括一些无关抗原,这里将对无关抗原的应答称为B,该应答就如同初次免疫一样
