I would agree that doctors don't have all the answers and can sometimes cause more harm than good. I also think we over immunize.
Some vaccines I understand (polio being one of them) but even if everyone immunized it would not get rid of it, it would just come back with a mutation that we wouldn't be ready for.
If memory serves me, the vaccination debate started because of Jenny McCarthy claiming vaccines cause autism. I recently saw an article saying the study that claimed that had falsified their data so it wasn't even accurate. I wish I remembered the link.
