NumbersMike Wagnitz, Chemist at the Wisconsin State Lab of Hygiene (WSLH) Toxicology Section, Madison, WI and NAA Advisory Board Member wrote THIS LETTER, published in Pediatrics, the magazine of the AAP:

Parents get angry when they see the following numbers listed on the internet. These numbers have been out there for everyone to read for years. They are mathamatical facts backed by references. The way to quell parental fears would be for someone like Dr. Parikh to address these numbers. Using propaganda is not going to work and only makes the situation worse.

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 

20 ppb mercury = Neurite membrane structure destroyed (Leong et al., Neuroreport 2001; 12: 733-37).

200 ppb mercury = level in liquid the EPA classifies as hazardous waste. 

25,000 ppb mercury = Concentration of mercury in the Hepatitis B vaccine, administered at birth in the U.S., from 1990-2001.

50,000 ppb Mercury = Concentration of mercury in multi-dose DTaP and Haemophilus B vaccine vials, administered 4 times each in the 1990's to children at 2, 4, 6, 12 and 18 months of age. Current "preservative" level mercury in multi-dose flu (94% of supply), meningococcal and tetanus (7 and older) vaccines. This can be confirmed by simply analyzing the multi- dose vials.

Holy cow. If I knew they (Pediatrics) were going to actually publish something I sent them I would have spent more than 5 minutes working on this. My letter in the American Journal of Public Health is much better.

Mercury, Vaccines, And Autism: One Controversy, Much Propaganda

In the article, "Mercury, Vaccines, and Autism: One Controversy, Three Histories" the author, while trying to sound impartial, misrepresents several facts in order to support his conclusions. He starts by citing the many findings of the Institute of Medicine (IOM) without mentioning that the IOM was commissioned by the CDC to issue a report on "Vaccines and Autism." The CDC approves, mandates, promotes, and distributes vaccines. He does not mention that every member of the IOM committee had ties to the vaccine program (1). There were no independent toxicologists on this committee. One would think this would be important when considering the safety of mercury in vaccines.

The author cites the inventors of thimerosal and writes, "extensive in vitro testing shows that thimerosal was 40 to 50 times as effective as phenol against Staphylococcus aureus." He then claims "concerns over neurotoxicity in infants receiving thimerosal from vaccines were never raised by medical or government authorities before the late 1990s." This is false. In 1982, an independent panel was convened by the FDA (2). The panel called for the removal of mercury, including thimerosal, from all over-the-counter products. It declared thimerosal as being both unsafe and ineffective. It was singled out as being "no better than water in protecting mice from fatal streptococcal infection." It was shown to be 35.5 times more toxic to embryonic chicken heart tissue than the aforementioned Staphylococcus aureus.

He goes on to declare that the "comparatively miniscule exposures [of thimerosal] involved in vaccines were well within all published guidelines for mercury exposure." Unfortunately, he never took the time to analyze a vaccine vial for mercury concentration. The Hepatitis B vaccine, administered at birth for over ten years, contained 25,000 parts per billion (ppb) of mercury in the multi-dose vaccine vial. The multi-dose DTP and Haemophilus B vaccine vials, administered 4 times each in the 1990s to children at 2, 4, 6, 12 and 18 months of age, contained 50,000 ppb mercury. According to the EPA, any liquid that contains more than 200 ppb mercury is to be classified as hazardous waste based on toxicity (3). It's hard to believe that a level of mercury 250 times higher than hazardous waste levels would be referred to as "miniscule." The fact is, on any given day of receiving even a single thimerosal containing vaccine in the 1990s, all published guidelines for mercury exposure were exceeded.

Several pages of the paper examine the toxicity of methylmercury and its past use as a fungicide. We are led to believe that this form of mercury is much different than ethylmercury, the type found in vaccines. This is in spite of the fact that ethylmercury was used for the same purpose. In fact, Ethylmercurric Chloride, the material used as a fungicide (which was banned long ago) is what is used to make thimerosal. This can be easily confirmed by looking in a Merck Index. We now know that this type of mercury deposits twice as much inorganic mercury in the brains of primates as compared to equal doses of methylmercury (4). Inorganic mercury, following the de-methylation of organic mercury, has been identified as the primary neurotoxic agent in primate studies (5).

The author mentions the book, "Evidence of Harm: Mercury in Vaccines and the Autism Epidemic" by David Kirby. It contains 436 scientific references. The author did not disclose if he read the book. This may have helped his argument since this book was read by many parents of autistic children.

We are then told about the impact of trial lawyers concerning this situation. The author does not disclose how much money has been awarded to trial lawyers who represent autistic children. It's my understanding that this number is zero.

Mr. Wagnitz is a chemist with the Wisconsin State Laboratory of
Hygiene, which is located at the University. He is NOT a member of the
faculty. There is a toxicology program run by the Department of
Pharmacy, and a Department of Food Microbiology and Toxicology.
However, there is no "Toxicology Department" at UW Madison.

you seriously don't think they will publish this??? the AAP may be so confused about the mercury that they may think his research is a good thing for mercury and autism

JB Handley

It is simply unbelievable that the AAP defends mercury in vaccines with numbers like this.

I find comfort in knowing that it is only a matter of time until the walls start crumbling (oh yeah, they already are!!)

At least we will all know where AAP stood!

Great job Mike!!!

Sue M

Excellent letter. For the sake of clarification... The title of the post reads "Mike Wagnitz in Pediatrics Magazine" but then goes on to say that he wrote this letter to the Pediatrics magazine. Question: Was the letter actually published? I just don't want to jump to conclusions :)

Craig Willoughby

Yep. But the CDC, the FDA, the IOM, the APA, and the various other alphabet soup organizations out there are so certain that its safe to inject in our children. Who are they kidding? Sadly, quite a few people here in America (or, as our illustreous Monkey-in-Office (Bush) says, "Mareka).

I wonder if Gerberding-aling-a ding dong (AKA-The Gerbil) has read this report.....
