H1N1 Flu Vaccine & Mercury
Does the 2009 H1N1 flu vaccine contain mercury?
These days just the word "mercury" is enough to induce a panic attack in otherwise calm parents. And the fact is, multi-dose vials of the 2009 H1N1 (swine flu) vaccine contain thimerosal, a mercury-based preservative that has been used for decades in the United States. Another fact? There is no evidence that thimerosal is harmful to pregnant women or fetuses.
However, vaccine companies are making preservative-free seasonal flu vaccines and H1N1 vaccines in single dose syringes for pregnant women and young children. Talk to your doctor if you're interested in more information about the preservative-free seasonal and H1N1 swine flu vaccines.
