Thimerosal Content in Some US Licensed Vaccines Szczepionki, które nie zawierają związku o nazwie THIMEROSAL (etylortęć) są w tabeli zakreślone na żółto. Można spróbować je zamówić przez aptekę.
From the Vaccine Safety Institute (http://www.vaccinesafety.edu/thi-table.htm) 1. A concentration of 1:10,000 is equivalent to a 0.01% concentration. Thimerosal is approximately 50% Hg by weight. A 1:10,000 concentration contains 25 micrograms of Hg per 0.5 mL.
2. A previously marketed lyophilized preparation contained .05% thimerosal. 3. COMVAX is not approved for use under 6 weeks of age because of decreased response to the Hib component. 4. ProHIBit is recommended by the Academy only for children 12 months of age and older. *. The new Engerix-B product contains only trace amounts of thimerosal (<1 mcg)

Thimerosal Despite the fact that thimerosal preservative has been effective in lowering the risk that vaccines could be contaminated by bacteria leading to serious infection, the United States Public Health Service agencies, including NIH, FDA, HRSA, and CDC, working collaboratively with the American Academy of Pediatrics and the American Academy of Family Physicians, took action in mid-1999 to begin removing thimerosal preservative from the vaccine supply. While the risk of harm from this source was only theoretical, the decision was made as a precautionary measure. The elimination of thimerosal preservative from vaccines was judged a feasible means of reducing an infant’s total exposure to mercury in a world where other environmental sources of exposure may be more difficult or impossible to eliminate. As a result of this action, all manufacturers of routinely recommended licensed pediatric vaccines are now producing for the U.S. market only vaccines that are thimerosal-free or contain trace amounts of thimerosal. The vaccines are supplied in single-dose vials which eliminates the need for a preservative.
