Do vaccines cause autism? That is the question on many parents minds these days. If you have a new child, especially if it’s a boy, and are going to vaccinate them, that is the big cloud that’s probably hanging over you.

I’ve got a whole book on this if you’re interested in reading more about it, but I’m going to summarize what I believe for you here.
