Thimerosal is a widely used vaccine preservative that is present in the majority of flu shots and other vaccines. Thimerosal is 49% mercury by volume, an extremely toxic chemical element that wreaks havoc on the nervous system, neurological function, and overall biological function . Each dose of flu vaccine contains around 25 micrograms of thimerosal, over 250 times the Environmental Protection Agency’s safety limit of exposure.
Mercury, a neurotoxin, is especially damaging to undeveloped brains. Considering that 25 micrograms of mercury is considered unsafe by the EPA for any human under 550 pounds, the devastating health effects of mercury on a developing fetus are truly concerning.
Though thimerasol is not entirely mercury, the mercury content is still extremely high, making it very toxic to the human body. Despite highly exceeding the EPA safety standards for mercury content by over 250 times, flu shots are still recommended for children over 6 months and pregnant women.
