I remember chatting with my friend (before I knew Claire had autism) about my fears with the MMR. It hadn't been disproven at that point, and I was worried. She was going to university at the time to work with Autistic children and she totally helped me out in regards to my fears.
She talked to a bunch of her professors who worked closely with Autism departments, none of them felt that the MMR caused Autism. They felt it was an unfortunate coincidence as mainly the signs for Autism really start to show around 12 months, which is the same time the MMR is recommended for children.
She did say however that there's a VERY small percentage of kids who the vaccines WILL make it worse. But that was like a percentage of less than 1%, and she said it was rare.
So I suppose that's somewhat of a correlation between vaccines and some sort of "injury"... I won't get into how I feel about Jenny McCarthy.
I find that people nowadays don't find the diseases that scary, as they've never witnessed them. There's a part of me that is also sad that so many people died of these diseases, and so much time and money was spent to find cures for them for people just to take them for granted now.
It sucks too as I don't feel its one of those decisions that one can say "respect mine, and I'll respect yours". Not vaccinating your child exposes other kids who aren't old enough to get them or elderly people to them. So its not just you, iykwim? Its tough because there's a fundamental part of me that feels that as parents, we should respect each others decisions on what they do with their kids.
But it wouldn't potentially hurt my kid if another parent decided to co-sleep or sleep train, formula or breastfeed, pierce ears or not, or any other hot topic that happens along our way.
Its really tough.
