1. Because people with lots of money and power don't want the study done. They have something to lose (money)
2. Because the US Gov't is convinced that any change to the US vaccination schedule will be a major catastrophe
3. Because fault would be found and the lawsuits would be enormous
Do vaccines cause autism? Yes, sometimes. (Hannah Poling) Are vaccines the only thing that cause autism? No. How do I know this? Because my unvaccinated son is autistic. Do I regret not vaxing him? Heck no! He would be much more severely affected (or not here at all) had I vaxed him with the typical US schedule. What really gets under my skin is that the vaccine debate is always reduced to Autism causing or not Autism causing. The schedule is insane and money driven regardless of Autism. There are many problems with the safety testing and conflicts of interest and on and on - Autism or no.
Amen. Exactly on target. Autism is just one of dozens of reasons I do not regret my decision to avoid all vaccines. Just the ability to read and reason carefully is enough.
I read several dozen articles, weighing the pros and cons, the risks etc, all evidence and all thought process pointed directly at not vaxing. I still read. Nothing has changed.
