Hell, I should have just told her to look up the CDC info and she could have saved all that money on a medical degree...
The question is why aluminum when things like calcium phosphate used as adjuvants work just as as well or better, are easier to implement into vacs and, most importantly, don't have a habit of collecting in the brain and causing toxicity simply b/c the body cannot rid itself of it. I'll let her know you don't see the problem, though, lol.
FTR, she has no choice in giving flu shots. I mean, she does, she can refuse to give them and they will fire her, but that's not much of an option. Every retail pharmacy she's worked for demanded this as part of her job description.
Yes, it really, really sucks. She hates that part of her job more than anything.
