One of my friends just made me facepalm with a comment of hers on facebook. She's a pharmacy tech and apparently anti flu vaccine. She just made the comment: "I guess I've just never understood why we inject ourselves with something we don't want to get."
So I very nicely explained to her how vaccines work, which I'm rather astounded she seems to be ignorant of being a pharmacy tech and all. If she already knows how they work and she still doesn't get it, I'm going to have to seriously doubt her intelligence.
