Thimerosal and Vaccines | Vaccine Safety | CDC
2024年7月31日 · Thimerosal contains ethylmercury, which is cleared from the human body more quickly than methylmercury, and is therefore less likely to cause any harm. Thimerosal is added to vials of vaccine that contain more than one dose (multi-dose vials) to prevent growth of germs, like bacteria and fungi.
Toxicity of ethylmercury (and Thimerosal): a comparison with ...
We have reviewed in vitro and in vivo studies that compare the toxicological parameters among etHg and other forms of mercury (predominantly meHg) to assess their relative toxicities and potential to cause cumulative insults.
Thimerosal is a mercury-containing compound that prevents the growth of dangerous bacteria and fungus. It is used as a preservative for flu vaccines in multi-dose vials, to keep...
Vaccine Ingredients: Thimerosal - Children's Hospital of Philadelphia
Some people have worried that thimerosal, an ethylmercury-containing preservative in some multi-dose preparations of influenza vaccine, could cause mercury poisoning either in children or affect the unborn children of pregnant women who receive this vaccine.

Much in the thimerosal debate hinges on the alleged similarity, or dissimilarity, of ethylmercury to methylmercury.
Thiomersal vaccines - World Health Organization (WHO)
2012年7月27日 · The findings confirmed the view that methyl mercury is not suitable for risk assessment of thiomersal. Brain concentrations of total mercury were threefold lower with thiomersal, compared with methyl mercury, and the average ratio of brain–blood concentrations of mercury was slightly higher for thiomersal-exposed infant monkeys.
Thimerosal in Vaccines Questions and Answers | FDA
When thimerosal is used as preservative in vaccines, it is present in concentrations up to 0.01% (50 micrograms thimerosal per 0.5 mL dose or 25 micrograms mercury per 0.5 mL dose).
