Swine flu vaccine and humen see?

How come government offering swine flu vaccine with out testing it first?? Why would they do that? They don't even know how to give support to people with it, they don't know how to cure it, how come will people survive if every vaccine own a little bit of disease in it. I can't understand that. What if this wouldn't work, how do they backing us? Can't they just take a blood example and test it beside vaccine?!
No, they can't test it on blood, because blood alone doesn't have an immune system, and it's the immune system's response to a vaccine that causes imperviousness. It needs to be connected to a person's immune system to test its effectiveness, which funds trials in people.
