Swine Flu! Please answer!?

The vaccine for swine flu is the EXACT same vaccine as the seasonal flu vaccine. It's made EXACTLY the same way, so there's no need for extensive testing! They already know it's safe! They use it every year! The only difference is it has one flu in it instead of 3, which the seasonal vaccine has. And the only reason swine flu is not already included in the seasonal vaccine this year is because all of the seasonal ones were already made at the beginning of this year. Swine is just an addition to it. There's no crazy, untested ingredient in swine flu vaccine that isn't already in the seasonal flu vaccine, except the actual weakened virus itself which you'll be exposed to anyway if you don't get the vaccine (except it won't be weakened then).
