Ethyl Mercury Versus Methyl Mercury
One of the proposed links between Mercury and Autism is Thimerosal, a compound that has been used in vaccinations. A new study [PDF of abstract] from the University of Washington, Seattle, USA has examine the different effects of ethyl mercury, used in Thimerosal, and methyl mercury, commonly used in industrial processes. Most of the toxicology data on mercury is based on accidental exposure to Methyl Mercury in the work place.
The study inject new born monkeys with either ethyl mercury (in the form of thimerosal) or methyl mercury in doses equivalent to that found in vaccinations for human babies. Mercury levels were then monitored and it was found that the ethyl mercury cleared from the body a lot quicker than the methyl mercury. Critically brain concentrations of total mercury were significantly lower by about three-fold for the thimerosal exposed infants when compared to the methyl mercury infants. This is important because mercury causes brain damage only through long-term exposure (a fact that gave us the phrase ‘as mad as a hatter‘). Thus if the body is cleaning itself quickly of the ethyl mercury, it doesn’t have the chance to build up and cause damage.

Comments on: Ethyl Mercury Versus Methyl Mercury
what is the difference between methyl mercury VS ethyl mercury?

Other than they are different chemical compositions of mercury I don’t know what the differences are. For further information I suggest the Mercury entry on Wikipedia: http://en.wikipedia.org/wiki/Mercury_%28element%29

A flu shot has 25micrograms of ethyl mercury. The EPA recommends limiting mercury to 0.1 micrgrams per kilogram of weight per day. The FDA (oddly enough) thinks 0.4 micrograms per kilogram of weight per day is “safe”. If the brain concentration for ethyl mercury is 1/3 that of methyl mercury, by my math that is still too high for infants and toddlers. As an example, 20 lbs = 9.1 kilograms. Using the less stringent FDA guidelines, 0.4 x 9.1 = 3.63 micrograms of mercury per day. This is more than SIX TIMES the “safe” level (by FDA guidelines) in a standard flu shot for a 20 lb toddler! By EPA guidelines it’s more than 24 TIMES the “safe” level. No thank you, vaccine maunfacturers.

Valerie Holstein, you are confusing “micrograms” and “micrograms per day”, which are two very very different things. By your own math you come up with a safe level of 3.63 micrograms of mercury per day for a sample toddler, and you site a level of 25 micrograms of ethyl mercury in a flu shot.
By the FDA guidelines you cite (and assuming no other exposure sources) it would be safe to give that toddler ONE SHOT PER WEEK, for life. By the more stringent EPA guidelines you cite it would be acceptable to give that toddler a flu shot every month, for life.
So no. A single shot or even one shot every couple of months is a non-issue, even by the the more stringent limits.
Studies have been done, and there is no link between vaccinations and the illnesses blamed on them. Children who do not get these vaccines get the same illnesses at the same rate. I’m all for mercury-free vaccines, but don’t scapegoat valuable lifesaving vaccines just because we are at a loss for the TRUE cause of autism or others. I’d give myself or my child a few dozen mercury-loaded vaccines… far safer and genuinely beneficial compared to all the diseases that vaccines prevnet.

Dear Anonymous:
You say “I’d give myself or my child a few dozen mercury-loaded vaccines…far safer and genuinely beneficial compared to all the diseases that vaccines prevent.”
Let’s take a look at what vaccines are CURRENTLY on the CDC Schedule and see if they all are indeed worse than injecting your child straight into an autistic prison, shall we??
3 Doses of HepB - a sexually transmitted disease. Is your child having sexual intercourse or using IV drugs?? Mine’s not!
3 Doses of Rotavirus - Rotavirus=Bad diarhea…um thanks, but we’ll deal with the diarhea…especially in light of the original recalls on the first round of this vaccine which caused intestinal blockages and killed several children.
4 Doses of DTaP - made with twice the pertusses toxin as when I was a child to really overload the developing immune system. Read the warnings on the vaccine insert - can cause encephalitis and death. A necessary vaccine, but poorly executed! These need to be split into single vaccines and given 1 month apart.
4 Doses of Hib - to help prevent meningitis
4 Doses of pneumococcal - to prevent ear infections. Only covers 8 of some 80+ strains of the pneumococcal bacteria. My son had this and 1 year later needed ear tubes b/c of 12 ear infections. Great vaccine!
4 Doses of IPV
Yearly doses of Influenza - 2 per year - Seriously???? When they get the vaccine wrong almost every year and it’s loaded with 25 mcg of thimerosal in each dose????
2 Doses of MMR
2 Doses of Varicella - Chicken pox??? Since when is that something for which we need a vaccine in childhood?? It STRENGTHENS the immune system!! The vaccine leads to greater chance of shingles later in life and only lasts for 10 years.
2 Doses of HepA
So, that’s a total of 38 shots between birth and 5. By my count, only a maximum of 16 are even questionably necessary (DTap, Hib, IPV, MMR, HepA). Do NOT be confused. The CDC Schedule is designed to keep the vaccine industry in business, parents at work and campaign dollars flowing into the right places. And you better thank whatever god you worship that your child has a good ability to excrete the toxic soup of chemicals in the vaccines they received and didn’t slip away before your eyes like mine did. You have no idea what it is like. I would take a bout of rotovirus or chiken pox or influenza ANYDAY over watching my son deal with autism EVERYDAY!
Educated Autism Mom

Actually, I can prove vaccines aren’t neurotoxins. I give these as examples.
University of Rochester did a new study on infants testing the levels of ethyl-mercury in their systems after given thermisal vaccine. Study shows that ethyl-mercury is expelled from the body quicker then originally thought. In fact, it is expelled from the body ten times faster then methyl-mercury, which is found in fish. The entire reason mercury is toxic is because it stays in the body and bio-accumulates in the brain, and sense the entire basis for”thermisol is evil” is that mercury is neurotoxin and mercury is mercury is mercury, this debunks the myth.
University of Washington, Seattle did their own study, which confirms the above.
A series of papers published in the most recent issue of New England Journal of Medicine suggests that exposure to ethyl-mercury has no effect on the neuropsychological functioning in children
The second part of this myth is “My kid got his shot, and then turned autistic” which also isn’t true. Actually what happened is autistic regression, a key point in the diagnosis is this syndrome. Many times, a child will seem normal until they’re 1 or 2 years old, and then suddenly and quickly deteriorated into autistic behavior. Considering that vaccines are given at this age, and this happens in non-vaccinated children just as often, it’s safe to call this a coincidence.
Mercury is only dangerous thought longer term exposure, ethyl-mercury is out of the system in four, there’s no way it has time to cause these kinds of problems.
I’d rather see this myth go down the toilet then watch a poor family have to bury their child because they fell for the anti-vaccine propaganda.
Educated mom, diagnosed on the spectrum.

I would assume that just because it clears [[ethyl-mercury, that is]] the system faster doesn’t mean it doesn’t have time to cause damage to the brain.
Each of the 6 BILLION people in this world react to things differently. What might clear out of your 2 year old might not clear out in mine.
No thank you.
Posted by: Anonymous October 21st, 2008 at 9:35 pm
Well, even if you don’t believe that fact ((despite the fact that is how mercury effects the body.)) then just look at the diagnosis of autism next to the introduction of thermisol into vaccines, and after it was removed. You’ll see the rate of diagnosis was already going up before it was given to the public, and continues even now years later.
Oh, and yet another study has been published disproving this myth. It’s being knocked down from all sides. Even the scientist who came up with this wacko conspiracy has been stripped of his title for preforming illegal procedures of minors.
Posted by: goche21 November 28th, 2008 at 8:18 am
Please dont be fooled by the “educated autism mom”. Do your own research on reliable websites such as the CDC and FDA sites and you will learn what the “educated autism mom” is saying is not accurate and she is not educated.
Posted by: ugottabkinddnme January 8th, 2009 at 10:01 pm
If they do unbiased research they will come to the same conclusions.
For example, the rate of diagnosis of autism was on the rise before thermisol was added to vaccines, and continues to rise even now that it’s been removed almost completely. The man who first introduced the MMR vaccine link almost went to jail for fabricating test results, and preforming illegal procedures on children. The information is there, vaccines are safe.

You know what? Do what you gotta do - if you don’t think the manufacturers of vaccines - in their multi-billion dollar industry - have a vested interest in continuing to INSIST that parents are wrong and that their unnecessary, overbearing, and forced requirements of vaccines do no harm, knock yourself out!
But when YOUR child transforms from a healthy, babbling, active baby into a zombie-like stranger in his own head, I bet you’ll want to know who was responsible for this outrage. And won’t you feel just the tiniest bit guilty for “vaccinating” against perfectly normal childhood illnesses, like chicken pox, and changing the whole course of your own, and your baby’s life? I have many “”vaccinating” friends whose children GOT the very diseases the were supposed to have prevented.
I’m with the “educated mom” - no, thank you. My children, husband, siblings, and I have all made it through chicken pox, flus, colds, and various other illnesses. If anyone in my family became autistic, I’d rest assured that I did nothing to cause it. And you?
Posted by: mauimama January 28th, 2009 at 10:32 pm
If you took the time to understand the science behind vaccines and how they work you’d know that vaccines do not cause autism, and that they prevent very dangerous diseases. I can rest assured that I am protecting my family, and other families, from diseases that have killed.
When we start seeing these diseases in developed countries, how will you feel? Sure you think you saved your children from autism, but will you end up putting them or another child in the grave? Some of these diseases kill one in twenty children! That is not a case of the sniffles, that is a serious infection.
How many kids have to die before you start looking into all of the research apposing this horrible myth? Why is death less serious then a rumor that vaccines somehow cause autism?

Most of Ethyl Mercury leaves the body after a few days but is there a way to measure what has been absorbed by the Brain and kidneys? As far as I know there is no blood test in existance that will detect Mercury levels already absorbed in the Brain and Kidneys. Elevated Creatinine levels in the Blood will point to Kidney impairment which could have been caused by Heavy metal poisoning

I believe anyone who wants to argue how fast ethyl mercury leaves the body needs to back up and start providing the facts as to whether it has ever been PROVEN safe to begin with. Even on the FDA website it clearly states how little Thimerosal was tested before being used in child vaccinations in the 1930’s. Autism was realized within a few years AFTERWARD. Also you need to do your homework on the fact that ethyl mercury is used in medicine because of its antimicrobial properties, science is only now beginning to understand how our bodies coexist with 1,000’s of bacteria in the mouth and throughout the intestines, many being found to be beneficial to both the digestive (i.e. probiotics) and immune system which are dependent on these for not only health but our survival. So in the 1930’s science nor medicine knew enough about the human body to declare any substance safe to inject into it(in many ways they still don’t). Speaking of bacteria, how about the ones that can be in the human body that, just like in salt and fresh water, convert inorganic mercury into a more toxic form of methylmercury? Lastly in 2005 the American Red Cross collected the blood from 10 newborns umbilical cords acroos the U.S. and when the Environmental Working Group had it tested they found that each one averaged over 200 chemical (many being toxic)and the heavy metal mercury was present at the time of birth, so now how safe do you think that 25 mg is to those babies or should I more properly say TOXIC to them? Its a shame the pharmaceutical companies have people like anonymous so brainwashed or perhaps anonymous is one of those rats that the pharma companies hire to sit on their pathetic asses and do nothing but watch sites like this to spread their poisonous viewpoints on?

Elemental mercury damages the body through bioaccumulation, which means it has to stay in the body long enough for enough of the substance to be absorbed and cause damage to the tissue. Ethyl-mercury just does not stay in the tissue long enough to cause that kind of damage. It doesn’t react to the body in the same way that Methyl or elemental mercury does. So, if it obviously reacts so differently, how can you claim that it treats the body exactly the same? I fail to see the reasoning there.
And Lisa, I suggest that before you try to educate ANYONE on history, you go to the library yourself. If you had any common sense or basic reasoning skills you would realize that autism may have been labeled in the 1930’s, but that does not mean that is when it made it’s first appearance. Autism has been around for centuries, but just not under that name. If you don’t believe me then go read on ancient “demon possessions” in young children, or the behavior of particularly “impossible” children.
Autism seems to be more out of control then it is because of how broad the diagnosis is these days.

I think it is interesting that the central topic here seems to be mercury, and no one is even mentioning all of the other materials that have huge propensity for neurotoxicity. Ethyl mercury may clear the system quickly, may not cross the blood brain barrier, but it is a well established phenomenon that monosodium glutamate does. Free glutamate is routinely used in science to kill test animals, induce obesity, and destroy brain/nerve tissue. It is a potent neurotoxin. It is also in vaccines.
What about all of the foreign animal proteins? Isn’t it common sense that the body was designed to digest these proteins before the amino acids are absorbed into the blood stream? Isn’t it common sense that a large foreign protein injected directly into the bloodstream could induce inflammatory, autoimmune reactions? Science aside, shouldn’t we at least be QUESTIONING the purported safety of something we are injecting directly into the bloodstream of a newborn infant?
Autism is not the only issue here. There are a myriad of developmental and chronic autoimmune disorders running rampant in our children today. As far as inducing such a rapid increase in these kinds of problems, it would seem likely, or at least reasonable that intravenous injection of known neurotoxins and foreign materials could be a main contributing factor. Last I checked, children were not dying from acute illnesses like measles, at least not with the advanced medicine we have today. For the most part, people are dying from chronic immune conditions. I believe this is because the body is confused. When the immune system is exposed to a foreign material via digestive, respiratory, or integumentary systems (the way nature designed), a full immune response is induced. When the body is exposed to a ‘watered down’ version of the same material via direct injection, the immune response is only partially stimulated. The part that is stimulated is the short term, immunological memory part-antibodies. The bulk of immune function, the part that is responsible for overall ability to clear the body of foreign materials, is left unstimulated. This makes it difficult for the immune system to function properly. It becomes hyperactive- hence allergies, asthma, autoimmune diseases.
The question in my mind is not so much about proving safety. It is about proving efficacy. Anyone can make any claims they want about the science, but the truth of the matter is that efficacy of vaccines has never been established scientifically. It has been assumed. So before we completely alter the means by which the body becomes resistant to disease, we ought to devote some time to determining how well that means actually works, and if the benefits outweigh the risks.

I believe there are still a lot of unanswered and unknown questions out there that really prevents us from determining whether or not vaccines cause autism. The number one question that has still been unanswered is what really causes autisim in the first place. Having this question unanswered really prevents us from determining whether or not these vaccines are negatively effecting the development of these children. So you honestly can’t be on one side or the other because no one really knows. You have to keep in mind that the make up of everyones’ bodies is different and that different chemicals, compounds, and even metabolites effect people different ways. You can say that oh only an acute amount in this or that study effected this group negativly, but what about that acute group? What makes them so different? Where the effects similar in this group or were there different results within that acute group? Most importantly, when exposed to this ethylmercury, how does it effect brain even as it only stays in the body for up to 8 days? How does it effect the nervous system? Can it be stored in the body, and if so, where does it store? Could it build up between different exposers and vaccines even after a year or so? Sure you may feel that vaccines aren’t to blame when autisim usually doesn’t show up until the child is 1 or 2 around the same time they are due for vaccinations, but how do you explain that to the parents of children who had a normal child up ’til the child was in his adolencent or even pre-teen years?
Until scientist are able to clearly answer all of these questions, we can only sit on the fence and do what we believe is best for our children and accept the consequences for our actions.

I’m rather disturbed by people who want to cling to the notion that a vaccine caused their child’s autism. I do not know what it’s like to have an autistic child, but I do know what it’s like to bury one due to a disease. So, would you rather have a child who has to live with autism, or have one die from something preventable.
