What folks would those be? Since it's my job to know everything about the flu, I do read about adverse vaccine reactions. Do you have the links to the CDC or to PubMed, the medical research article database, where a large number of adverse reactions are documented? Or do you "know" about this plethora of adverse reactions because you saw some anti-vax screed about them? Unless the adverse events are documented by medical professionals, they are nothing more than hear-say.
It's times like these where I miss Bill Maher's 'Get Over Yourself' awards that he used to hand out on 'Politically Incorrect'. If a 'medical professional' didn't document it...never happened. OMG...ROTFLMAO!
