Hi Ryan,
Not sure if vaccines cause autism or not, but these numbers sure concern me:
- 0.5 parts per billion (ppb) mercury = Kills human neuroblastoma cells (Parran et al., Toxicol Sci 2005; 86: 132-140).
- 2 ppb mercury = U.S. EPA limit for drinking water (http://www.epa. gov/safewater/ contaminants/ index.html# mcls).
- 20 ppb mercury = Neurite membrane structure destroyed (Leong et al., Neuroreport 2001; 12: 733-37). Think Alzheimer's!
- 200 ppb mercury = level in liquid the EPA classifies as hazardous waste based on toxicity characteristics.

- 700 ppb mercury = level of mercury in large predator fish.
- 25,000 ppb mercury = Concentration of mercury in multi-dose, Hepatitis B vaccine vials, administered at birth from 1991-2001 in the U.S. but no other country. Is this why our rate of autism is 10 times higher than Iceland and Finland?
- 50,000 ppb mercury = Concentration of mercury in multi-dose DTaP and Haemophilus B vaccine vials, administered 8 times in the 1990’s to children at 2, 4, 6, 12 and 18 months of age and currently “preservative” level mercury in multi-dose flu, H1N1, meningococcal and tetanus vaccines. This can be confirmed by simply analyzing the multi-dose vials.
