Your immune system keeps you healthy by labeling different illnesses and making a specific remedy against them. You will never get the exact same virus twice, because once you've gotten sick once, your immune system learns what that virus looks like, and makes a specific block against it ever getting into your body again. You might think that can't be true, because you get the same cold every winter. In actuality, every time you get a cold, it is a slightly different mutation of the same virus. If it were exactly the same, you couldn't catch it twice, because your body already knows how to fight it.
A vaccination works by giving you a tiny piece of a dead virus. Its enough like the disease that your immune system works to come up with a defense against it. So you've developed an immunity to that particular sickness without having to get sick from it. There is some controversy about vaccinations though, because opening your body up to a piece of a dead disease is supposed to be safe, but people have adverse reactions to vaccinations sometimes.
So you don't really get the disease of polio for example, but you can't catch polio because your immune system knows what polio looks like and knows how to fight it off. It recognises it right away and knows how to get rid of it.
