So a vaccine is designed in order to engage that biology, in order to provide antigens that will stimulate specifically your immune system.

所以疫苗的作用就是参与这个生理活动,提供抗原 来刺激你的免疫系统

Now, if I was a person that was designing a vaccine and I noticed that this was the response that it got, that antibodies were produced, they reached some intermediate level, they started to fall, I would say, "Well I haven't stimulated the immune system enough, let me re-boost, let me give another dose of antigen."

现在,如果我正在研究一种疫苗,我注意到机体会对这种疫苗产生应答,也就是会产生抗体,当抗体浓度达到中等水平后,就开始下降,就可以说,疫苗对免疫系统刺激还不足,我需要提高抗原浓度,让我再把剂量再加大一倍

The antibody that they stimulate is antibody that's specific to this antigen that was presented earlier.

这些由辅助性T细胞,刺激增殖产生的抗体是,对应之前出现的抗原而产生的
