...I've heard this a lot. I also think it's foolish to jut blindly accept everything I'm told. So, the next time you hear that bad things happening as the result of a vaccine is just a myth, throw this in their face: CSL Biotherapies indentifies likely reason for Fluvax problems - Pharmaceutical and Biotechnology News - Pharma Letter Virus traces in Fluvax cause of children's convulsions Febrile Adverse Events CSL confirms Fluvax manufacturing tied to convulsions in children - FiercePharma AND...if you think that this kind of thing doesn't happen in the U.S., then why would the CDC set up a whole system to monitor adverse reactions??
