Mercury concentrations and metabolism in infants receiving vaccines containing thiomersal: A descriptive study

Pichichero et al. The Lancet

Thiomersal is a preservative containing small amounts of ethylmercury that is used in routine vaccines for infants and children. The effect of vaccines containing thiomersal on concentrations of mercury in infants’ blood has not been extensively assessed, and the metabolism of ethylmercury in infants is unknown. The authors aimed to measure concentrations of mercury in blood, urine, and stools of infants who received such vaccines.
