Jen McCarthy blinded them all with her bewbs. I haven't seen any substantial evidence that vaccines are a serious health risk. I also haven't seen any substantial evidence that vaccinations are as wonderful as claimed. Too many factors at play. It is a fact that flu vaccines may as well be snake oil. I suspect some vaccines are quite useful and some less useful and some worse than useless (like flu vaccines), but because of the nature of the topic all we get are these stupid shouting matches.
