Explain why and how the immune system uses vaccination for protection.
Question asked by: eerihe

Asked on: 09 Oct 2009

Vaccination is to some extent a little counter intuitive and goes back to Edward Jenner and the first vaccination against the smallpox.

The idea is to give an injection of the thing that makes you ill, but crucially in a tiny quantity such that it won't actually cause infection but so that your body can see it and develop antibodies so that you are prepared should the actual vector itself attack you through infection.
