Letter to the Editor: Mercury and Vaccines

A chemist from Wisconsin who specializes in mercury testing sent the following letter to the Milford Patch.

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.
  • http://www.epa.gov/epawaste/hazard/tsd/mercury/regs.htm
  • 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.

Wake up folks! It's all about the heavy metals! Europeans are much more aware of this than Americans. Research, and use your critical thinking skills...this is really serious!

I'm quite skeptical of this 'chemist' who 'specializes in mercury testing'. First: any chemist would understand the difference between an element (ie: mercury) and a compound (ie: thimerosal). They would also understand that the reactivities are not equivalent, nor are the toxicities. The true colors come out when the 'autism' correlation is suggested. Since thimerosal was removed from nearly all vaccines in 2001 - why is the 'incidence' of autism still rising if it's the thimerosal to blame? Second: anyone who specializes in environmental 'testing' would also understand the reasons why there are different thresholds for exposure. Route and frequency matter. Any source which is potentially a chronic (ie: daily or greater - such as water) has an extremely low allowance. There's the usual scare tactic - 25,000 ppb and 50,000 ppb. Inflate the numbers so they look larger and therefore more worrisome. A vaccine containing 0.01% thimerosal as a preservative contains 50 micrograms of thimerosal per 0.5 mL dose or approximately 25 micrograms of mercury per 0.5 mL dose 1 ppm = 1 microgram per milligram. So 25 micrograms per 0.5 mg = 50 ppm. Which is the same amount as 50,000 ppb, but it doesn't seem quite as 'scary' since it doesn't have all those zeros after it. No 'chemist' would write 50,000 ppb. We'd write 50 ppm.

Thanks Linda!
