Hi Sue,
I can't tell you what to believe in I can only put out information that may or may not give you a different perspective.
Personally I went into alternative medicine because I experienced the negatives of the talking heads.
Anyway, here is another article that goes a bit deeper and it also addresses the polio vaccines.
I guess with your mom and have often questioned this with my own gramma would she have gotten her dementia if she had not gotten the flu shots. Prior to getting them she was as sharp as a tack.
I have several mothers that I see in my practice that have children with autism and it is their firm belief that it was caused by the MMR vaccine.
I don't think the original makers of such vaccines and medicines were out hurt anyone only to help. Remember the article on the gerson treatment I had posted last summer or so. He was a regular MD that found a cure for cancer just by diet and he was killed off because he wanted to spread the good news. But the greedy SOBs that have absolutely no concern other than to make a buck and gain control and power over the masses had to quiet this man so it did not get out to the world the way Max Gerson had intended to.
It is not just in medicine it is everywhere. Flapjack posts on all of this stuff but most people don't want to believe it.
Love and Joy
Karen
