I believe the Vaccine industry is a multi BILLION dollar industry. I believe...no I know there is a vaccine victim compensation fund because, some kids get really hurt and die from vaccine's. Did you know that for many many years the number one cause of polio was the polio vaccine? I could go on and on, but I won't bore you.
As for Autism, I do believe it's multi pronged problem. It's both genetics and some outside trigger which is why it is so hard to figure out. Think of troubleshooting your car, if it's just one issue causing the problem....no biggie. If there are multiple issues happening, that makes it a lot harder.
And for the record I do think vaccine's are necessary and for the most part good. People need to educate themselves, and not fall for all the hype, in either direction.....
