A number of affluent countries are moving to eliminate thiomersal (thimerosal), an ethylmercury preservative, from vaccines as a precautionary measure because of concerns about the potential adverse effects of mercury in infants. The WHO advocates continued use of thiomersal-containing vaccines in developing countries because of their effectiveness, safety, low cost, wide availability and logistical suitability in this setting.The guidelines for long-term mercury exposure should not be used for… 

When science is not enough – a risk/benefit profile of thiomersal-containing vaccines

Data is reviewed and summarised that overwhelmingly indicate continued use of thiomersal is safe in those countries where it is most needed, and that there is a real danger that this controversy may result in the loss to the world of thuomersal as a preservative, simply from popular pressure.

Thiomersal (also known as thimerosal, merthiolate) is an organomercurial derivative of ethylmercury that has been used very widely, and for a very long time, as a preservative in vaccines in their

Hair mercury in breast-fed infants exposed to thimerosal-preserved vaccines

It is speculated that dose and parenteral mode of thimerosal-EtHg exposure modulated the relative increase in hair-Hg of breast-fed infants at 6 months of age.

Toxicity of ethylmercury (and Thimerosal): a comparison with methylmercury

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 are reviewed.

Safety of thimerosal containing vaccines. Statement of the Consultive Committee of Immunizations on behalf of the Chilean Infectious Diseases Society

After a thorough review of published studies on pediatric use of thimerosal-containing vaccines, and of position papers from international expert groups, the Consultive Committee of Immunizations of the Chilean Society of Infectious Diseases concludes that there is no solid evidence of adverse events associated with the use ofThimerosal containing vaccines in infants and children.

Thiomersal in Vaccines

As a precautionary measure, efforts are under way to remove or replace thiomersal from vaccines and providers should anticipate the availability of more vaccine products that are thiomeric-free over the coming years.

Suggesting that thiomersal hypersensitivity wits not associated with an increased risk of vaccination reactions, however, individual cases of severe reactions to thiomeric demonstrate a need for vaccines with an alternative preservative.
