Isn’t the thimerosal in the multi dose injectable vials dangerous?
A. Thimerosal has never been shown to be of any danger in the small doses seen with the flu vaccine. A 10 dose vial has 250 micrograms of thimerosal (25 micrograms per vaccine). By comparison a tuna fish sandwich has 28 micrograms of mercury. BOTTOM LINE: There is no evidence that thimerosal poses a risk.
