From 1996 to 2000 there was a big rise in ASD.something like 1 in 88.,During that time was when Dr.Wakefield's Theory about the MMR vaccine tainted with mercury.Since that..,theres been a sharp Decrease in the people dignosised with ASD,Why? Well the goverment had to dispute the claims & discredit the doctor because were talking about ALOT of class action law suits if it was true.When you hear a Pharmacuital companys ad on tv,listen to the the side effect's Disclamer of the drug.Im not talking just 4 hr erections but some advertised Drugs have MORE Side effects than GOOD effects and these are FDA APPROVED!
