JS Online: Most flu shots contain mercury, but few know it
About 80% of all flu shots distributed in the United States contain a mercury-based preservative called thimerosal. Thimerosal consists of 49.6% ethyl mercury, an anti-bacterial, anti-fungal that allows manufacturers to sell the vaccine in large, multi-dose containers without fear of contamination.
A typical 0.5 milliliter flu shot contains 25 micrograms - or 50,000 parts per billion - of mercury.
The EPA classifies a liquid with 200 parts per billion of mercury as hazardous waste. The limit for drinking water is 2 parts per billion.
Using the standards set for methyl mercury consumption - the kind that's in fish - an average 130-pound person getting the flu shot would exceed the daily limit by more than four times. A 22-pound baby would get more than 25 times the amount of mercury considered safe. And doctors are recommending that many babies and children get two flu shots this season.
