In 1994 Japan was forced, due to the 1993 MMR (Mumps, Measles and Rubella) scare*, to drop the requirement to vaccinate against measles and rubella. Autism rates still rose.

One can thus more or less rule out the vaccine as being a cause off of this rise in autism rates. This isn’t all that relevant to the mercury case though – because the MMR vaccine has never had any mercury in it.

For mercury, we look at thimersal - which is present in trace amounts in some flu vaccines, after it was removed from all the others in 2001/2002 as a political decision. Thimersal contains ethylmercury, which only sticks around in the body for a few days and then gets kicked out. The bad stuff is methylmercury, which you get in sea-food.

So even if mercury was a factor in causing autism - if you wanted to avoid it you would be better just not eating fish.

As to that supposed impact, as of yet the proponderance of the data shows that there is likely no link between autism and mercury poisoning.

Mercury poisoning is a real thing – but it has totally different symptoms to autism. If the two were related you would expect them to have more in common.

For more on this check out Antiantivax, Respectful Insolence and Science Based medicine.

*The scare in Japan came about because their version of the MMR vaccine used the Urabe strain as its mumps component, which caused some cases of aseptic meningitis.

I know a little something about this since having a vaccine injured child. Several cases of acute mercury poisoning from thimerosal-containing products were found in the medical literature with total doses of thimerosal ranging from approxi…mately 3 mg/kg to several hundred mg/kg. These reports included the administration of immune globulin (gamma globulin) (Matheson et al. 1980) and hepatitis B immune globulin (Lowell et al. 1996), choramphenicol formulated with 1000 times the proper dose of thimerosal as a preservative (Axton 1972), thimerosal ear irrigation in a child with tympanostomy tubes (Rohyans et al. 1994), thimerosal treatment of omphaloceles in infants (Fagan et al. 1977), and a suicide attempt with thimerosal (Pfab et al. 1996). These studies reported local necrosis, acute hemolysis, disseminated intravascular coagulation, acute renal tubular necrosis, and central nervous system injury including obtundation, coma, and death. (IOM)

In its report of October 1, 2001, the IOM’s Immunization Safety Review Committee concluded that the evidence was inadequate to either accept or reject a causal relationship between thimerosal exposure from childhood vaccines and the neurodevelopmental disorders of autism, attention deficit hyperactivity disorder (ADHD), and speech or language delay. Additional studies were needed to establish or reject a causal relationship. The Committee did conclude that the hypothesis that exposure to thimerosal-containing vaccines could be associated with neurodevelopmental disorders was biologically plausible.

The Committee believed that the effort to remove thimerosal from vaccines was “a prudent measure in support of the public health goal to reduce mercury exposure of infants and children as much as possible.” Furthermore, in this regard, the Committee urged that “full consideration be given to removing thimerosal from any biological product to which infants, children, and pregnant women are exposed.”

A typical 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 the kind of mercury 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. Doctors are recommending many babies and children get two flu shots this season.

Honda/Rutter compared Japanese children who received the MMR vaccine with “unvaccinated” Japanese children and found no difference in regressive autism rates: MMR-Vaccine and Regression in Autism Spectrum Disorders: Tokio Uchiyama, Michiko Kurosawa, Yutaka Inaba J Autism Dev Disord (2007) 37:210–217.

However, the “unvaccinated” children were not. These were children who had received the single measles and rubella vaccines. So that study also goes to support the findings presented here that it is the vaccines and/or the combinations of vaccines which are causally associated with autistic conditions.

The “preponderance of the data shows that there is likely no link between autism and mercury poisoning.” Actually, autism advocate Julie Obradovic examined the fourteen studies that are used to prove safety.
http://www.ageofautism.com/200......html#more
In Julie’s words, “Each and every study was conducted and/or funded by someone who patents, manufacturers, promotes, endorses, profits from and/or defends in a court of law—vaccines.” The denial of any link between vaccines and autism comes with a lot of pharma ties at the Centers for Disease Control and Prevention. Hundreds of employees have waivers because of their financial ties to the vaccine makers. The last head of the CDC, Dr. Julie Gerberding, a long-time denier of any link, is now the head of the vaccine division at Merck Pharma.

Parents need to educate themselves about the risks from an ever-increasing vaccination schedule. Pretending that ethyl-mercury is safe and only methyl-mercury is harmful flies in the face of scientific research. The truth is, the mercury used in vaccines doesn’t get “kicked out” after a few days, it’s gone from the blood and can quickly pass the blood-brain barrier and enter the brain. There it is found to accumulate at a higher rate than methyl-mercury. Check out the work of Dr. Thomas Burbacher at the U. of WA. He’s done extensive research on this question.

Okay, here’s the thing:

In 1994 it stopped being mandatory to vaccinate your kids for MMR in Japan.

Japan, every now and then (as happened in 2007) suffers a measles epidemic, which pretty clearly indicates that not everybody is vaccinating.

So you would expect, if there is a link to the vaccine, for the rate of autism diagnosis to go down. It hasn’t.

Now the FDA mentions cases of thimersal poisoning, and it is consistent with the symptoms of mercury poisoning:

http://www.fda.gov/biologicsbl.....28.htm#tox

But not with autism. They specifically point out that recommending thimersal be removed from vaccines was due to the precautionary principle, and that subsequent study has shown no difference in autism rates between kids with differing dosages of thimersal.

It also mentions a 2004 study that updates the 2001 one:

In 2004, the IOM’s Immunization Safety Review Committee issued its final report, examining the hypothesis that vaccines, specifically the MMR vaccines and thimerosal containing vaccines, are causally associated with autism. In this report, the committee incorporated new epidemiological evidence from the U.S., Denmark, Sweden, and the United Kingdom, and studies of biologic mechanisms related to vaccines and autism since its report in 2001. The committee concluded that this body of evidence favors rejection of a causal relationship between thimerosal-containing vaccines and autism, and that hypotheses generated to date concerning a biological mechanism for such causality are theoretical only.

“Each and every study was conducted and/or funded by someone who patents, manufacturers, promotes, endorses, profits from and/or defends in a court of law—vaccines.”

In other words, people who actually work with vaccines produce studies on vaccines. Who else would it be?

Bruce, the methylmercury in fish is tightly bound to the protein in tissue. For comparison to the ethlmercury in vaccines, it would have to be extracted out and then injected. Also, fish is consumed by mature adults who on average weigh 20 times more than infants exposed to ethylmercury. You need to adjust for this and blood volume differences. Also, unlike ingestion, intramuscular injection provides rapid access to the bloodstream. The reason ethymercury cannot be found in the blood is because it is much more unstable than methylmercury. This mercury is still in the body just not in the blood anymore as ethylmercury. As Ms. Dachel noted, ethylmercury leaves behind twice as much divalent mercury (Hg++) in the brain of baby primates as compared to equal doses of methylmercury.

Bruce, your article has so many errors that if you were in college-the prof. would mark it an F.
How about independent scientists doing studies -in other words-people that have nothing to loose if the study shows a connection between vaccines and autism. I cannot speak of Japan as much as the US, but I can tell you that thimerosal was not out of childhood vaccines in 2002. It was a slow process that took many more years. Also in the US, it was put back with copious amounts in 2004 into the flu shots -recommended now for everyone over six months of age and it’s recommended for pregnant women.
Who told you the symptoms of mercury poisoning are different from symptoms of autism? You are also completely wrong here. They have many similarities Ms Dachel and the others have presented important information so I won’t get into what they wrote. Just to note that the rise in the autism numbers(on all the charts)go hand in hand with the rise in the number of vaccines given to babies and children. Do you have a better theory than vaccines? If so, I’d like to hear it

Epidemiological studies are not proof – neither is the IOM’s review of epidemiological studies proof.

We need some biological studies; we should test the current vaccination schedule on primates before human kids.

A reminder: the Japanese MMR was completely different than the MMR that has been used in the USA since 1971.

Ms. Dachel, you seem to be big on the thimerosal bit. Why? It is gone (and newsflash: the flu vaccine is available without thimerosal, and actually very few kids get it). It is like you are stuck in a a time warp. Especially when you bring up Bernadine Healy who left the NIH almost twenty years ago, and whose more recent career choice were questioned (Red Cross, and a tobacco lobby). Then some news reports by credulous reporters. That does not create much confidence in your data or evidence.

Perhaps you can tell us why Sallie Bernard could not find DTaP vaccine with thimerosal in 2001. Here is her request:

Hi all:

A group of university-based researchers needs several vials of the older DTaP vaccine formulations which contained thimerosal for a legitimate research study. If anyone knows an MD who might have some of these vaccines or knows where to get them, please email me privately.

Thank you.

Look

Thimorsal was first mandated out in 1999, it took until 2002 for it to be removed from most vaccines, with flu shots being the only exception.

It wasn’t added back in in 2004, it was never completely taken out of flu shots.

With flu shots it is used in their production and then removed, leaving trace amounts behind. There is less thimersal in a flu shot today, then there was in 1999.

Aside from this there are non-thimorsal alternatives available for the flu shot, a fact which has had no impact on autism rates.

Thimersal was not invented in the 1990′s, it was first introduced in 1930. Why the sudden jump in autism rates we have seen in the last twenty years? The explanation could be more of it getting used, except usage has clearly gone down with no impact on the rate of autism diagnosis.

In 1999 when thimersal was mandated out of most vaccines by the exact same people who are proclaimed to have a conflict of interest on this issue, it was due the precautionary principle. That is an adrmistrative, not scientific decision, and a good one at the time.

“Better safe than sorry” might end up with things getting withdrawn that shouldn’t be, but it also restricts the victim count for things that should be withdrawn.

That said more research since then has been done on a epidemilogical basis, and found no link.

The profit motive is out now because alternative vaccines are on the market.

Read Ben Goldacre’s Bad Science.

Drug companies do that with all medicines before they go on to human testing. It is a quite strenous process to get a medicine approved.

November 12, 2010 at 6:21 pm

paul5of6, please present a valid study plan that guarantees that the subjects in the placebo group do not become harmed by actually getting measles, mumps, pertussis, tetanus, Hib and other diseases (including passing rubella to a pregnant woman). Those are all diseases that are returning, and in an area of reduced herd immunity will be passed to some of the placebo group.

Please familiarize yourself with the rules governing medical testing on children (they are available online). They were put into place after studies like you are proposing were done on disabled children in institutions like Willowbrook, and children in developing countries.

This study, Efficacy of Measles Vaccine, was done in Nigeria. Check out Table 1. So what happened to the placebo group? Did all of them survive?

Vaccinated vs Unvaccinated – please keep the medical profession away from this argument and similarly consign the pharmaceutical industry to outer space then take at random any number of autistic kids and count how many were never vaccinated. Take those out of the equation – there will be none I believe then count again the autistic kids who were vaccinated and check off their vaccines – I am confident there will be none who simply received MMR. Then repeat the exercise until the truth leaps off the page autism is found only in kids who have had the DPT and variously other vaccines. Ther common factor is mercury and autism is the World’s first shelf life disaster.

Why do you continue with this lie? The DTP vaccine has not been used for over ten years, having been replaced by the DTaP. You have been told countless times there are completely unvaccinated autistic persons, including Kim Stagliano’s youngest daughter.

About the measles vaccine and vax versus unvax, read the 1963 paper I linked above. Look at Table 1. Tell us what happened to the group that did not get the measles vaccine. Did they all survive?

What? The first well documented case was Hugh Blair of Borgue in a 1747 court case, and its not like the historic record is absent of evidence of autism going back further than that.

Edward Jenner first used cowpox as a smallpox vaccine in 1796.

Did the pioneers of vaccination also invent time travel, and just not tell any of the rest of us?
