When debating the safety of vaccines pro-vaccine advocates  regurgitate “the dose makes the poison” phrase  ad nauseam. What they mean by this is the dose of the many toxins inside all vaccines have been deemed too low to cause any toxicological reactions from the body. In other words, the phrase is their way of saying there is not enough of the toxin to be poisonous. Nevertheless, there are a few flaws in this argument. The first being the mode of entry for said toxins is never really considered when looking at the safety of the dose. The problem with this is there is a huge difference between a toxin that enters via digesting or inhaling it compared to one that enters via being injected into the muscle in our arm. For example, when we eat of food that has aluminum in it only a fraction of one percent of the aluminum ingested actually makes it into the bloodstream. Whereas, when you inject it into the muscle in the arm nearly all the toxin makes it to the bloodstream (what does not typically accumulates in near by fat cells). Yet, many safety studies on the toxins inside vaccines focus on how the body handles the toxin when we ingest them! Secondly, no human body is the same, people will have toxicological reactions to chemicals at different doses — to suggest there is a safe dose for everyone of any of the toxins in vaccines is misinformation at best, and is not backed by science. Lastly, the statement overlooks the synergistic toxicity — how chemicals interact with each other when they come in contact inside the body.

There is not a lot of studies on synergistic toxicity yet, but the CDC is not in the dark about it either  — as seen in this publication:

Exposures to mixed stressors can produce health consequences that are additive, synergistic, antagonistic, or can potentiate the response expected from individual component exposures. This is the complex problem that faces environmental scientists and public health officials in setting and carrying out public health policy for the general environment, consumer product and food and drug safety, and the protection of workers.

Mercury is typically the first thing brought up when speaking about dangerous vaccine ingredients because, individually, it is a well-known neurotoxin that can lead to neurodevelopmental disorders. Because of this, single dose vaccines no longer contain mercury, however it is still found in many multi-dose vaccines today! Moreover, the synergistic reaction of mercury and other metals have been studied with some very troubling findings:

  • In this study, the synergistic relationship between lead (0.01mg/L), mercury (0.001mg/L), cadmium  (0.005mg/L) and arsenic (0.01mg/L) were looked into. Individually the dose is considered very low and safe for the mice. Although when they are combined, it “induced toxicity to the brain, liver, and kidney of mice.”
  • In this study a dose of mercury that will kill 1 out of 100 rats was introduced into rats, followed by a dose of lead that will kill 1 out of 1000 rats.  What they found was startling, every single rat exposed to the combination died!
  • This study looked at the synergistic relation between aluminum, copper, lead , mercury, and cadmium and found that  these metals act synergistically with the mussel’s own okadaic acid to kill cells.

The metals in the above listed studies, spare Aluminum, are not found in vaccines, yet still hold some merit on this topic because in today’s world, we are exposed to these metals semi frequently. However, when looking at the synergistic toxicological reactions of the ingredient in the vaccines, the relationship between Mercury and Aluminum is far more important than the others.

Dr. Boyd Haley, Professor and Chair of the Department of Chemistry at the University of Kentucky, has produced some of the best literature on the subject. However, his articles are hard to find now. For instance, this Dr, Bernard Windham, MD article says “the level of mercury thimerosal in vaccines has been shown to be highly neurotoxic, but the effect was found to be much larger due to the synergistic effect with aluminum, which is also in most vaccines.” His references for this was a paper (in which Haley was the lead scientist on) presented to the Institute of Medicine Immunization Safety Review Committee, however when you click on the hyperlink the site no longer exists. Moreover, after hearing lectures from Dr. Haley and Dr. Bernard Rimland (founder of the Autism Research Institute) at that year’s Doctors for Disaster Preparedness meeting, Dr. Donald W. Miller, Jr., MD also wrote an article in which he cited one of Dr. Haley’s papers that also brings you to a page that does not exist.

The opening part of Dr. Millers article pertains to mercury’s relationship with Autism, Alzheimer’s and other degenerative diseases, and the dangers of mercury fillings (which is very interesting, but really related to this topic). Towards the end of the article it gets to the synergistic relationship between aluminum and mercury stating:

Another important factor with regard to mercury on the mind, which officials
at the CDC, FDA and the professors in the IOM do not consider, is
synergistic toxicity – mercury’s enhanced effect when other poisons are
present. A small dose of mercury that kills 1 in 100 rats and a dose of
aluminum that will kill 1 in 100 rats, when combined have a striking effect:
all the rats die. Doses of mercury that have a 1 percent mortality will have
a 100 percent mortality rate if some aluminum is there. Vaccines contain

Prior to 2001, Dr. Haley testified for the U.S. House of Representatives’ Committee on Government Reformon on the dangers of mercury filling. His testimony also got into on the possible synergistic toxicity between mercury and other toxins. The president of the American Dental Association wrote a scathing retort defending the use of the amalgam. Then in May of 2001, Dr. Haley went point by point to counter everything the ADA president claimed, ending with a summery of the synergistic relationship between aluminum and mercury that said:

As was proven by the tobacco situation, trying to find any significant negative effect of one product (amalgams) related to any disease through epidemiological studies is very difficult and complex. To do this with mercury would be difficult because of the synergistic effect two or more toxic metals or compounds (e.g. cadmium from smoking) may have on the toxicity of the mercury emitted from amalgams. For example, one publication showed that combining mercury and lead both at LD1 levels caused the killing rate to go to 100% or to an LD100 level (12). An LD1 level is where, due to the low concentrations, the mercury or the lead alone was not very toxic alone (i.e., killed less than 1% of rats exposed when metal were used alone). The 100% killing, when addition of 1% plus 1% we would expect 2%, represents synergistic toxicity. Therefore, mixing to non-lethal levels of mercury plus lead gave an extremely toxic mixture! What this proves is that one cannot define a “safe level of mercury” unless you absolutely know what others toxicants the individual is being exposed to. The combined toxicity of various materials, such as mercury, Thimerosal, lead, aluminum, formaldehyde, etc., is unknown. [bold added for emphases]

Unfortunately, when dealing with synergistic toxicity of mercury other metals are not the only thing that we need to worry about. As strange as this may sound, multiple studies showed the combination of metals (including Mercury) and some pathogenic microorganism resulted in the metals being more readily absorbed throughout the body. Conversely, this study on Mercury’s synergistic relationship to a parasitical infection found “subtoxic doses of mercuric chloride (HgCl2) exacerbate disease outcome in SJL mice resulting in increased foot-pad swelling and increased parasite burdens.”

Moreover, testosterone also has a synergistic relationship with Mercury. In a 2001 affidavit to Congress,  Dr. Haley had this to say:

“We therefore decided to test the effects of both female and male hormones on the neurotoxicity of thimerosal. The results were eye-opening. For example, 50 nanomolar thimerosal causes less than 5% neuron death within the first three hours incubation and 1 micromolar testosterone causes no significant death within this time frame. However, mix these two together and 100% neuron death was observed at the earliest time point checked.

This represents a severe enhancement of thimerosal toxicity (see Figure 6).


Further, at 12 hours the neuron death effected by 50 nanomolar thimerosal alone could be reversed by 1 micromolar estrogen. Estrogen also significantly reduced the testosterone enhanced toxicity of thimerosal.”

Additionally, Dr. Haley once again testified in front of the House Government Reform Committee in 2002, where he briefly expanded on Mercury relationship with hormones, stating:
Additionally, in this same system the female hormone estrogen decreases thimerosal’s toxic effects. In contrast, the male hormone testosterone greatly increases the toxicity. This may explain the 4 to 1 ratio of boys to girls that become autistic and the observation that boys represent the vast majority of the severe cases of autism.

The synergistic toxicity of the other ingredients inside vaccines have not been studied to the same extent as Mercury has. However, the little studies done on Aluminum’s synergistic toxicology with other chemicals found some of the same horrifying results as seen with Mercury. Neil Miller’s Vaccine Safety Manual for Concerned Families and Health Practitioners: Guide to Immunization Risks and Protection is considered one of the better researched books on the safety of vaccination. Inside the book he references neurosurgeon, Dr Russell Blaylock’s studies on aluminum, to say this:

We now know that aluminum causes significant abnormalities in neurotubules, microscopic tubes in neurons essential to their function, and these abnormal neurotubules are strongly associated with Alzheimer’s disease. Aluminum enters the brain by a number of mechanisms, for example by attaching to glutamate and fluoride. With the widespread use of the excitotoxin glutamate as a food additive and fluoride being added to drinking water supplies, aluminum absorption is common. In addition, injected aluminum can complex with fluoride within the body to produce a compound, fluoroaluminum, that has a number of harmful effects, including brain injury. There is some evidence that fluoride can trigger microglial activation and excitotoxicity, which in combination is particularly injurious to the brain.

The impact of fluoroaluminum toxicity has been confirmed by a few other studies as well.

To conclude the article, I have decided to post some videos on the subject because for many of us, it is much easier to watch a lecture on the subject than read study after study. The first is a very good presentation by Dr. Stephanie Seneff, Senior Research Scientist at MIT, where she discusses the synergistic toxicity of aluminum and glyphosate (the main ingredient in Roundup ) and the connection to autism.

This is a very long lecture, but very good. However, many of us will not have the time to watch the whole thing, at least not at one time. So, here is a more condensed 8 minute video where she explains what is happening when aluminum/glyphosate/ and glutamate (which correspondences with Dr. Blaylocks works) come in contact in the human body.

Here’s an hour-long lecture given by Dr. Haley in 2003, which goes very in-depth into the science showing everything discussed in the this article on Mercury’s synergistic toxicity. I really love listening to Dr. Haley speak because he does not pull punches. In his lectures he routinely calls the CDC (and other governmental regulatory agencies) out for lying about the science. He even has a pseudo punchline saying he feels like he is arguing with the town drunk when dealing with them. Anyone that proves the CDC to be liars, while making funny jokes, is someone I can get along with! Simply put– Dr. Haley is the man.

The small sample size of studies looking into synergistic toxicity has shown that claiming a toxin is safe because of its INDIVIDUAL toxicity is simplistic and endangers people. We need to start looking into the SYNERGISTIC relationship of all chemicals in vaccines before the industry can even begin to say their products are safe.
