as far as i've read the vaccine for h1n1 is a little over twice as effective against h1n1 as the regular flu vaccine is against regular flu. i haven't read much on the new mutation to the h1n1 but i think the current swine flu vaccine is still effective against it. also i haven't read much about the new strain being any more deadly or anything either.
