The virus is not killed so It's a live virus, which is actually going to infect your intestinal system and reproduce.

病毒没有被杀死,那么它就是活性病毒,也就意味着它将会,侵入你的肠道系统并且会繁殖

So, they don't start killing all the cells in your respiratory system; they only kill the cells that are harboring the virus.

所以它们不会杀死所有呼吸系统内的细胞,只杀死那些被病毒感染的细胞

To slow the spread of the virus and relieve the strain on the country's health system, the government has set up a national pandemic flu service, where people who suspect they're infected can get a diagnosis and prescription for antiviral drugs over the phone or Internet.

In fact, a real powerful virus would skip the respiratory system altogether, even better than a cold virus.

事实上，真正强有力的病毒,会跳过呼吸系统，比感冒病毒好的多。

You could imagine that you've got virus that's propagating inside your cells, making more and more virus, your immune system really responds well to that.

你可以想象,病毒在你的体细胞内繁殖,数量越来越多,你的免疫系统对此反应非常之强烈

A problem with adenoviruses is that your immune system recognizes them, and if your immune system recognizes the virus then it can attack the virus and eliminate it from the body.

关于腺病毒有个问题,免疫系统会识别腺病毒,如果免疫系统识别了这些病毒,就会进而攻击并从体内清除病毒

耶鲁公开课 - 生物医学工程探索课程节选

Because this is not a virus at all, but it's a virus subunit, your body doesn't respond to it as strongly, your immune system doesn't respond to it as strongly.

因为这根本不是病毒,而是一个病毒亚基,机体对其反应不是那么强烈,免疫系统不会产生强烈的应答

How is your immune system going to recognize that this virus is there causing bad results if it's living inside of a cell and doing all its business inside a cell where antibodies can't get to it?

你的免疫系统怎样才能识别,作恶多端的病毒呢,如果它隐藏在细胞中进行繁殖,而抗体又无法进入细胞,那该怎么办

耶鲁公开课 - 生物医学工程探索课程节选

If the immune system recognizes only small pieces of the virus and mounts an immune response to that, how about if I just take these pieces of a virus like some structural subunit, some piece of protein and use that as a vaccine?

如果免疫系统识别出病毒的一小段,就可以诱发起免疫应答,那么如果我仅用一小部分病毒,比如一些结构性亚基 一些蛋白质的片段,来作为疫苗的话,会如何呢

Or you get a cold, the cold virus takes hold, the viruses start replicating inside of you and it takes some time for immune system to gear up to eliminate it, so we're used to thinking about responses that take some time.

或者你得了感冒,感冒病毒扎根在你的身体中,病毒开始在你体内复制,免疫系统需要一定时间做好准备去消灭它,所以我们曾认为免疫反应需要一定时间
