As humans we're great at seeing things in black and white, not so great at nuance and shades of grey. It's easier to come to blanket conclusions than have to think each thing through. Sometimes that's valid, sometimes it's not. At this point in my life I am more in agreement with el gato malo that vaccines need to be evaluated one by one. I have no doubt you think that because I don't fully agree with you, I'm uninformed. There are vaccines I haven't and wouldn't take, and others that I would. To each his own.
