'Trace' is
not the word to use when describing mercury in vaccines.

In 2003, Bayer petitioned California's Office of Environmental Health Hazard Assessment (
OEHHA) to take thimerosal off the list of reproductive toxics. The OEHHA responded

"The scientific evidence that PMA and Thimerosal cause reproductive toxicity is CLEAR and VOLUMINOUS."

"The evidence for its reproductive toxicity includes severe mental retardation or malformations in human offspring who were poisoned when their mothers were exposed to ethylmercury or thimerosal while pregnant."

"Mercury spilled on a school room floor is a toxic event: the school is shut down, the hazmat team called in, young people decontaminated, health screenings are done, and a major long term clean-up occurs.

But, inject mercury into an infant and it's called a well-baby visit."

Myth: Thimerosal was removed from vaccines in 1999.

Truth: The Physicians' Desk Reference, which annually lists all U.S. drug ingredients, shows many childhood vaccines still contain the full amount of thimerosal.

Here is a current list of vaccines containing thimerosal.

Myth: Only a trace amount of thimerosal is used when added to vaccines.

Truth: Thimerosal is added at a concentration of 1:10000. That is equivalent to 100,000 parts per billion (ppb). Half of thimerosal (C9H9HgNaO2S) is mercury. That makes 50,000 ppb mercury in the vaccine.

• 2 ppb mercury is the mandated limit in drinking water

• 200 ppb mercury in liquid waste renders it a toxic hazard

• 25,000 ppb is found in infant flu shots

• 50,000 ppb is found in regular flu shots -- recommended for children, pregnant women, the elderly...

In different terms, there are 250,000 nanomolars Hg in a 0.5 ml flu shot.

It only takes 4 nM Hg to cause failure in the dendrites responsible for immune response and to cause cell death in brain neurons.

Thimerosal is
toxic to developing neurons at 1 nM (1 ppb).

In other words, exceptionally low levels of thimerosal can impede neuron growth and function without actually killing the neurons.

Myth: Ethylmercury from a vaccine is less toxic than methylmercury from fish or the environment.

Truth: A paper published in 2005 showed that baby primates injected with ethylmercury retain twice as much inorganic mercury in their brains as primates exposed to equal amounts of ingested methylmercury.

Both are forms of organic mercury. Organic converts to inorganic inside cells and becomes trapped. The cells start failing.

Myth: There are extensive volumes of data demonstrating thimerosal is safe.

Truth: This statement is the exact opposite of the truth.

The only studies suggesting it is safe to inject humans with thimerosal are epidemiological studies done by the producers, distributors and administrators of vaccines.

Much of this disinformation is published in
Pediatrics which is owned by the American Academy of Pediatrics (AAP).

These epidemiological studies are the same variety of studies used by the tobacco industry to claim that smoking does not cause lung cancer.

To find the truth about thimerosal start by reading the Material Safety Data Sheet (

Then go to the medical search engine
PubMed and type in thimerosal.

You will get references to over 1300 published papers concerned with the extreme toxicity of thimerosal, except for the papers published with Pediatrics' bias.

Here is a
table of thimerosal content in currently licensed vaccines according to the FDA.

The table lists 'trace amounts' of thimerosal ranging from 0.00012% to 0.0033%.

That's equivalent to 1,200 ppb to 33,000 ppb.

Research shows thimerosal is toxic to neurons at 1 ppb.

Those 'trace amounts' are still 4 to 5 orders of magnitude higher.

Other vaccines are listed as ‘thimerosal-free’ or ‘mercury-free’.

But thimerosal is still used in the production process for many of those vaccines, after which an effort is made to filter it out.

Unfortunately the mercury has already bonded to proteins used in the vaccines and cannot be completely removed.

There is no safe level of mercury exposure.

It is a misconception that California has completely banned the use of mercury in vaccines.

California Health and Safety Code
section 124172 rules that pregnant women and children under three years of age are still allowed to receive vaccines with 0.5 µg mercury per 0.5 ml dose.

In the case of flu vaccines they are allowed to receive 1.0 µg mercury per 0.5 ml dose.

The law also makes provision for the State to allow higher levels of mercury in cases of short supply or threat of bioterrorism.

This can be done for up to 2 consecutive 12 month periods (24 months total).

There is no safe level of injected mercury.

It has been known for a long time that mercury from thimerosal crosses the placenta and moves rapidly from blood to brain.

this study from 1975, pregnant rabbits were injected with thimerosal.

In just 6 hours the mother's blood level of mercury decreased 75% from peak.

At the same time the fetal levels of mercury rose 4x in the liver, 3x in the kidney, and 2x in the brain.

Thimerosal is
synergistically toxic with other chemicals.

In 2004 the CDC's Chief of the Organic Analytical Toxicology Branch gave a
presentation to the Institute of Medicine (IOM).

On page 21 he showed the following chemicals linked to Autism Spectrum Disorders (ASD) --
thimerosal, thalidomide, lead, ethanol, valproic acid, and retinoids.

If you are insured under Medicaid, then your shots are more likely to contain thimerosal because those shots cost less than "thimerosal-free" versions.

The fact that ongoing medical treatment is considerably more expensive
after exposure to thimerosal hasn't been factored into that short-sighted budget decision.

This page has information regarding a site that helps calculate mercury received through vaccines.

Leftover flu vaccine is considered highly toxic hazardous liquid waste -- yet thousands of leftover vials are discarded into municipal landfills each year .

Thimerosal is still used in some cosmetics. For instance in
these "cake" mascara products.

The FDA has
never required manufacturers to conduct adequate safety testing on thimerosal and ethylmercury compounds.

Here is a
timeline covering the basic history of thimerosal.
