Interesting reading, thanks for the links. I am familiar with some of this. I do know that there was a study about MMR and autism, but despite the very conclusive findings that there is no link between MMR and autism this vaccine in particular still is avoided by many. For example I have a friend with an autistic son, he is adamant the vaccine caused the autism, despite the evidence saying otherwise. The HIV theory is an interesting one, I am wondering if there are any studies to demonstrate a link in this respect? I am not sure I believe all of it at this point without evidence to back it up, but I would like to do more research on the topics. Thanks for the links.
