the manufacturer isn't guilty of any sort of negligence here. it's understood that there is some risk. the guardians accept the risk when they make the vaccination choice. suing the vaccine company for this would be like suing the peanut butter manufacturer for setting off an unknown allergy. it's a freak accident. in legal terms, an "act of god". hey, nobody ever said god wasn't an asshole...

personally? i think the flu vaccine is a little overkill. they're useful for older people and very young people, but healthy people between five and 60 don't really need it - we can produce our own antibodies. i agree that the idea of vaccinating everybody yearly is being driven more by the economics underlying it than by public health concerns. more serious vaccinations? well, yeah, the risk is worth the benefits and we should all keep up....
