The other thing that I want to do today is try to tie this discussion on vaccines a little bit more closely with what we talked about last week, in terms of what happens inside your body when you receive a vaccine or when you're exposed to an antigen, and how the immune system actually responds to that.

还有就是,我希望可以,把今天关于疫苗的讨论,与我们上周讲过的内容,结合得更紧密一些,当接种疫苗,或者是接触抗原时,人体将会发生怎样的变化,以及免疫系统对疫苗产生何种应答
