The case of thimerosal in vaccines

One of the paradoxes of the success of vaccination in the 20th century is that people are more aware of the risks of vaccines than they are of the benefits. Many individuals have never encountered someone who was negatively impacted by polio, measles, rubella, or any of the host of childhood illnesses for which we now have vaccinations. One of the most frequently-expressed concerns about vaccines pertains to thimerosal, a mercury-containing compound that used to be a minor component of some common vaccines. At high levels, thimerosal can be toxic, hence the concern. In a survey of the vaccinations to which children are commonly exposed, it was determined that "an infant 6 months old who received all recommended vaccine doses on schedule could be exposed to up to 187.5 _g of mercury" (Freed et al. 2002: 1154).In terms of hazardous conditions likely to be caused by high doses, the most commonly-reported side effects were allergic reactions such as skin sensitization or, at very high doses (more than 1000 times higher than would be found in the vaccines), thimerosal was found to cause "neurologic and renal toxicity" (Freed et al. 2002: 1155).

In setting standards for minimum exposure, the FDA's Center for Biologics

Evaluation and Research (CBER) based its guidelines for exposure to thimerosal ethyl mercury on existing methyl mercury guidelines. "Based on these calculations, the CBER determined that potential exposure to mercury from the recommended childhood vaccines in the first 6 months of life could exceed the EPA methyl mercury guideline, but not the ATSDR, FDA, or WHO guidelines. However, the CBER was unable to determine with certainty whether exposure to thimerosal in vaccines was harmful" (Freed et al.….....
