In their presentation, the authors hypothesize that thiomersal, a mercury-containing preservative may be the cause of the association.

The findings from these studies do not challenge the safety of existing thiomersal-containing vaccines in infants.

Thiomersal has been used since the 1930s in the manufacture of some vaccines and other medicinal products.

These studies give further support to the safety in infants of thiomersal-containing vaccines in the amounts used in existing vaccines.

The Committee continues to review relevant scientific studies concerning the safety of thiomersal as they become available.

Q: What would be the health impact of restricting thiomersal-containing vaccines ?

As with vaccines that contain thiomersal, safe limits have been defined for organic mercury compounds in these products.

There is no evidence of toxicity in infants, children or adults, including pregnant women, exposed to thiomersal in vaccines.

Is there research ongoing to evaluate the relative effectiveness of alternative preservatives to thiomersal ?
