First of all, anyone with a basic knowledge of biology should know the difference between injection and ingestion, one goes to the bloodstream, the other to the GI Tract. Biologically they are much different, and that should end the argument right there with just simple biological logic. Let's go a little deeper but also try and keep it simple.
Thimerosal is a vaccine preservative and well known neurotoxin which is 49.55% mercury by weight (56.73% "ethyl mercury" by weight).
When ingested, most of the mercury in tuna does not enter the body, but passes out in the stool. The mercury that does absorb is methylmercury. Absorbing through the gut, first through the liver. This is called "First pass". The mercury going through the liver is conjugated by glutathione. Then that conjugated glutathione is passed out in bile and then stool. (Dr. Robert Murdoch)
The mercury in thimerosal is ethylmercury, when injected it is metabolized (converted) into the more toxic and harmful methylmercury. Because it is injected, it avoids the 'first pass' through the liver where it could be filtered, instead it circulates through all other tissues and organs. Mercury has a high affinity (binds well with) certain tissues, including neurological tissue, brain, kidneys, etc. So, in short then, the most harmful, long-term-toxic, "inorganic" mercury is retained in bodily tissue (Dr. Murdoch, Dr. Paul G. King). Anyone can look up bioaccumulation of mercury in the body and the half life. It's not pretty.
Further, "It is distributed primarily in the central nervous system, kidneys, liver, and skin. Mercury crosses the blood brain barrier and the placenta; infants and the fetus are the most at risk for toxicity to occur. Mercury exposure by expecting mothers has been shown to cause neurological abnormalities. Infants exposed in utero to mercury have shown developmental delays. In addition, the possibility of a link between mercury exposure and neurological disorders such as autism and attention deficit hyperactivity disorder has been evaluated.
Concentrations of thimerosal in vaccines and immunoglobulins range between 0.005 and 0.02%, a non-toxic concentration. However, a concern exists, not from exposure to a single vaccine, but that over a relatively short time span, children can be exposed to multiple vaccinations containing thimerosal. This repeated exposure might put children at risk for mercury toxicity.
The FDA has admitted that the safety of Thimerosal, when used as a preservative, has not been established to the regulatory standard, "sufficiently nontoxic..." This fact was established in a three-year investigation by a United States House Committee and set forth in the "A. Findings" section of its published 2003 report as set forth in Title 21 of the United States Code of Federal Regulations (21 CFR) at paragraph 610.15(a)[21 CFR 610.15(a)]
The problem is the House Committee study only looked into the effects of a single product, not the effect of multiple products (many different vaccines over a short period of time). There are no studies showing the safety of mixing different heavy metals such as Al (Aluminum) and Thimerosal, there are physical studies of mercury and aluminum in open air experiments which show rapid oxidative stress and violent reactions. No tests have been done on what happens when these elements meet together in lets say the brain or organs.
The literature that comes with most vaccines admits that...'has not been evaluated for its carcinogenic or mutagenic potential, or its potential to impair fertility'
The fluval vaccine warns 'safety and efficacy has not been established in pregnant women' and yet it continues to be recommended to them. So what happens when all these substances are mixed?
Synergistic Toxicity
And that brings us to consider synergistic toxicity , that is the combining of more than one toxic substance in a cocktail to be injected and the dangers that entails.
Safeminds explains:
"...when exposed to two toxins [or more], the toxicity level is far greater than the additive toxicity levels of the two toxins."
"A good example demonstrating 'synergistic toxicity' is a 1978 study on mice (Shubert et al. Combined Effects in Toxicology -- A Rapid systematic Testing Procedure: Cadmium, Mercury & Lead. J. of Toxicology & Environmental Health 4:763, 1978). The study took the amount of mercury salt that kills 1 in 100 mice and 1/20th of the amount of lead salt that kills 1 in 100 mice. When these amounts of mercury salt and lead salt were administered, the synergistic toxicity of these two toxins killed 100 in 100 mice:"
"If Additive toxicity, one would expect 1 + 0.05 = 1.05 mice to die (1 or 2)" "With Synergistic toxicity, the results were: 1 + 0.05 = 100 mice died" And further "There is significant potential for unexpected 'synergistic toxicity' effects from vaccines, particularly for a susceptible population that may already have high toxin levels due to a lessened ability to excrete toxins. Yet synergistic toxicity of vaccines has not been studied -- studies have focused on only individual toxicity of a single component of the vaccines (e.g. mercury or measles virus)" [Emphasis mine]
Out of all the vaccine debates I have watched since my research on vaccines began back in 2009 I have yet to hear synergistic toxicity brought up once. This seems acutely important and integral to the debate. Certainly Aluminum is toxic as well, as I will show later. Some other synergistic toxicity studies have been done showing low level concentrations of metals, but when combined, caused toxicity.
So, let's get this straight, thimerosal was never tested by any of our health agencies and was used in vaccines anyway from 1930-2004 (and still in some), and finally removed from most because of public outcry and then the government began to study it and decided yes, it's probably not safe (see footnotes above). The same will likely happen with Aluminum in 20-30 years after the public outcry again, but how many children and people will have had to suffer until then? Short 2 minute video clip of Hearings on Thimerosal.
Pro vaxxers say "Ah but there's no Thimerosal in vaccines anymore!!" It's interesting to note is that of the few vaccines that is given to infants that still has thimerosal in it is Hep B and DipTet (and Flu shot that is recommended to mothers now). So, the claim that it has been removed from all vaccines is a lie and misdirection. If they give it to all newborns then all the newborns are getting that thimerosal. "It was removed from many child vaccines in 2002 but remains in some vaccines (e.g., hepatitis B virus and influenza)" . And they get multiple doses of different cocktails.
Summing Up
As you can probably tell, the Can of Tuna Argument is moot at this point, and as you continue reading the studies below you'll begin to see even clearer why. They can't hide the fact that these substances are toxic even at low doses, and especially in multiple doses. Considering the other factors such as synergistic toxicity and the Governments own findings (as well as studies below) we can put that lame argument to rest. The Vaccine Injury Compensation Program has paid out $3.1 billion dollars to vaccine injury/death claims so far, when will they admit that they are not safe? Even the Supreme Court had to admit that vaccines were in a category of 'unavoidably unsafe' products.
The real question now is, after all the government hearings, findings and studies, why is thimerosal, or aluminum, still being used at all? And why do our health Czars keep lying to us?
Anything with "pro" in front of it smacks of religious overtones where the end result is to control a population, rather than give it freedom.
