SWINE FLU Do they have a flu shot to prevent it yet?

I live in England and it swept through England like a disease, but yet I didn't get it. Only like 8 people from my country died of it but those 8 people already had health problems. If you have a very very weak immune system then there's a higher chance you'll die of it. If your a healthy person your body will fight it off just like any other flu virus. They do flu shots but they mainly give it to the vulnerable people such as pensioners, babies and children.
