How do I know if my H1N1 vaccine had mercury in it?

I’ve received different information on the H1N1 vaccine. Some shots have mercury and others don’t? I’ve read that the multi-dose version may contain mercury, but I’m not even sure how what the “multi-dose” version means – or even if that’s what I received?

All the multi-dose vials contain 25 mcg of mercury per dose. That’s a large amount of mercury. The single dose vials contain no mercury. The pre-filled syringes contain either no mercury or 1 mcg of mercury. If it is Novartis brand pre-filled syringe, it is 1 mcg. The other brands of pre-filled syringes contain no mercury.

Most likely, you got the vaccine from a multi-dose vial containing 25 mcg of mercury per dose, because the majority of the vaccines are from multi-dose vials.

The multi-dose vials contain 10 doses. The single dose vials contains one dose. So the multi-dose vials are bigger. Did you see the vial they used? Would you remember what size it was? You can go to a flu shot clinic, look at the vials, and ask whether they are multi dose or single dose. Then you can compare the size to the one that you got the vaccine from.

Did you get any paperwork regarding the vaccine when you got it? Can you call the place where you got it?
