Vaccines💉疫苗原理

1. So all vaccines are trying to do the same thing. They're trying to give your immune system a heads-up to be prepared should you ever be exposed to the actual virus. 2. They are new technology. They're doing something really amazing, where they're giving your body a little piece of RNA, which is the genetic code that your body needs for your own cells to start making little tiny fragments of this new coronavirus. 3. So your body's not making the whole virus. You can't get the infections from the vaccine, but your body gets the code to make just the spike protein. And then bymaking that protein, your immune system sees it, takes note. It's like, “Okay, going to get ready should we ever get exposed to this.” 4. In the meantime, that RNA that got injected into you from the vaccine, it disappears quite quickly. It's very fragile. 所有的疫苗都在试图做同样的事情。它们试图给你的免疫系统提个醒，让其做好准备，以应对万一你接触到真正的病毒。 它们是全新技术。它们在做一些非常神奇的事，给你的人体一小段核糖核酸，这是人体需要的遗传密码，能让自身的细胞开始制造这种新的冠状病毒的小片段。 所以你的身体并非在制造整个病毒。你不会因为疫苗而感染，而人体得到的遗传密码用来只制造刺突蛋白。然后通过制造这种蛋白质，你的免疫系统看到了它，并记下来。这就像，“好的，去准备，以防万一我们暴露于此。” 与此同时，通过疫苗注射到你体内的核糖核酸很快就会消失，它非常脆弱。
