These pro-vaccine arguments come from the CDC –

Thimerosal Use Prevents Vaccine Contamination

Thimerosal is a mercury-containing preservative that is added to multi-dose vials (vials containing more than one dose) of vaccine to prevent contamination and growth of potentially harmful bacteria. This may occur when a syringe needle enters a vial as a vaccine is being prepared for administration. Such contamination could cause serious local reactions, illness, or death.


It is true that harmful bacteria can enter during manufacturer of vaccines. In the 19th and early 20th centuries, people sometimes died after vaccination when the vaccine site got infected and turned gangrenous. There is a photograph of this on the CDC’s website, here:

However, that is one of the reasons that antibiotics are added to vaccines, to prevent contamination in the lab and vaccine site infections. With antibiotics, thimerosal is not needed in vaccines to achieve this purpose. The primary function of thimerosal in vaccines is as a preservative.

Many Studies Have Found Thimerosal In Vaccines To Be Safe

Thimerosal is a very effective preservative that has been used since the 1930s to prevent contamination in a number of products including some multi-dose vials of vaccines.

Data from 19 studies show no convincing evidence of harm caused by the low doses of thimerosal in vaccines, except for minor local injection site reactions like redness and swelling at the injection site.


The CDC’s ‘factsheet’ was not sourced at the time of writing this page (7th January 2010). It linked to another page specifically on thimerosal but again this was not sourced. If VAN failed to source our information, the DOH and public would come down on us like a ton of bricks and rightly so, yet it seems the CDC can do it.

The CDC and other officials have known for DECADES that thimerosal causes harm. They actually had a review of it in 2000, called ‘Scientific Review of Vaccine Safety Data Link Information'(June 7-8 2000), and the report was leaked, where they showed concern about thimerosal in vaccines. Here are a few extracts of what became known as the ‘Simpsonwood Report’:

‘There was a recognition that the culmulative exposure that children recieve from vaccination may exceed at least one of the guidelines that is recommended, that of the EPA…it was desirable to remove mercury from vaccines as it is a potentially preventable source of exposure and that if it was able to be removed, it should be removed as soon as possible’ (page 12, Simpsonwood report).

Why the need to remove it as soon as possible if it isn’t harmful?

‘There is very little pharmacokinetic data concerning ethylmercury, there is very limited data on its blood levels. There is no data on its excretion, it is recognised to both cross placenta and blood-brain barrier.’

So they know it can affect unborn babies and that it can enter the brain and cause brain damage.

‘The data on its toxicity is sparse. It is recognised as a cause of hypersensitivity. Acutely it can cause neurologic and renal toxicity, including death, from overdose.’ (page 15).

So its not all that safe, then.

‘What does it mean exactly if a child has a low exposure or a high exposure? Basically because all vaccines have thimerosal. Is it a difference in being on time with your vaccination schedule? At 3 months of age some kids have received more vaccines than others so what we are looking at is how well the children are after their prescibed regimen of vaccinations’

I.e. they have no idea, it’s an experiment.

‘Finally, and this is the toughest one of all, how do we know it’s a thimerosal effect? Since all vaccines are thimerosal containing, how do we know it’s not something else in the vaccines like aluminium or the antigens?

In conclusion, the screening analysis suggests a possible association between certain neurologic, developmental disorders. Namely tics, ADD, speech and language disorders and exposure to mercury from thimerosal containing vaccines before the age of six months.’ (page 50).

So they’re ADMITTING there’s an association between mercury in vaccines and ADD and other disorders!

Dr. Johnson, one of those present, says on page 204 of the report:
‘Forgive this personal comment, but I got called out at eight o’clock for an emergency call and my daughter-in-law delivered a son by c-section. Our first male in the line of the next generation and I do not want that grandson to get a Thimerosal containing vaccine until we know better what is going on. It will probably take a long time. In the meantime, and I know there are probably implications for this internationally, but in the meanwhile I think I want that grandson to only be given Thimerosal-free vaccines”.

So there you have it, Dr. Johnson, the State Public Health Officer for Michigan and member of ACIP, refusing to let his grandson get a thimerosal containing vaccine when it is okay for everyone else!

For the full leaked report with even more alarming disclosures, see:

Vaccine manufacturer Merck also say in their literature that even tiny amounts of thimerosal may cause considerable damage to health and may even be lethal:

Studies Showing Thimerosal Harms

Burden In Children With Autistic Spectrum Disorders

Doctors found that autistic patients had high levels of mercury in their blood, and high levels of mercury excreted in their urine after chelation therapy (the removal of heavy metals from the body).

‘This study shows a strong association between increased
urinary mercury concentrations following three days of treatment
with DMSA and the presence of an autistic spectrum disorder. The
statistically significant association persists when vaccinated cases
are compared with matched vaccinated controls.’

They also concluded a direct relationship between mercury in childhood vaccines and autistic disorder.

‘Moreover, our findings appear to confirm previously published
epidemiologic evidence showing a direct association between
increasing mercury from thimerosal-containing childhood
vaccines and neurodevelopment disorders in children. These
studies showed that there was a two to sixfold, statistically
significant increased incidence of neurodevelopment disorders
following an additional 75-100 mcg dosage of mercury from
thimerosal-containing childhood vaccines in comparison to thimerosal-free childhood vaccines.’

(Journal of American Physicians and Surgeons Volume 8 Number 3 Fall 2003).

Neurodevelopmental Disorders After Thimerosal Containing Vaccines

This study represents the first epidemiological evidence based on tens of millions of doses of vaccine administered in the US, that associates increasing thimerosal from vaccines with neurodevelopmental disorders. Specifically, an analysis of the Vaccine Adverse Event Reporting System database showed statistical increases in the incidence rate of autism, mental retardation and speech disorders after thimerosal containing DTaP vaccines in comparison with thimerosal-free DTaP vaccines.

The male/female ratio indicated that autism (17) and speech disorders (2.3) were reported more in males than females after thimerosal containing DTaP, whereas mental retardation (1.2) was more evenly reported among male and female recipients.

Acute control adverse reactions such as death, vasculitis, seizures, ED visits, gastroenteritis and total adverse reactions were reported similarly after thimerosal and thimerosal free DTaP vaccines. An association between neurodevelopmental disorders and thimerosal containing DTaP vaccines was found.

Even Tiny Injections of Thimerosal Can Cause Autism

Thimerosal, an ethyl mercury compound, is used worldwide as a vaccine preservative. We previously observed that the mercury concentration in mouse brains did not increase with the clinical dose of thimerosal injection, but the concentration increased in the brain after the injection of thimerosal with lipopolysaccharide, even if a low dose of thimerosal was administered. Thimerosal may penetrate the brain, but is undetectable when a clinical dose of thimerosal is injected;

In conclusion, MT-1 and MT-3 mRNAs but not MT-2 mRNA are easily expressed in the cerebellum rather than in the cerebrum by the injection of low-dose thimerosal. It is thought that the cerebellum is a sensitive organ against thimerosal. As a result of the present findings, in combination with the brain pathology observed in patients diagnosed with autism, the present study helps to support the possible biological plausibility for how low-dose exposure to mercury from thimerosal-containing vaccines may be associated with autism.

Mitochondrial dysfunction, impaired oxidative-reduction activity, degeneration, and death in human neuronal and fetal cells induced by low-level exposure to thimerosal and other metal compounds

Thimerosal (ethylmercurithiosalicylic acid), an ethylmercury (EtHg)-releasing compound (49.55% mercury (Hg)), was used in a range of medical products for more than 70 years. Of particular recent concern, routine administering of Thimerosal-containing biologics/childhood vaccines have become significant sources of Hg exposure for some fetuses/infants. This study was undertaken to investigate cellular damage among in vitro human neuronal (SH-SY-5Y neuroblastoma and 1321N1 astrocytoma) and fetal (nontransformed) model systems using cell vitality assays and microscope-based digital image capture techniques to assess potential damage induced by Thimerosal and other metal compounds (aluminum (Al) sulfate, lead (Pb)(II) acetate, methylmercury (MeHg) hydroxide, and mercury (Hg)(II) chloride) where the cation was reported to exert adverse effects on developing cells. Thimerosal-associated cellular damage was also evaluated for similarity to pathophysiological findings observed in patients diagnosed with autistic disorders (ADs). Thimerosal-induced cellular damage as evidenced by concentration- and time-dependent mitochondrial damage, reduced oxidative-reduction activity, cellular degeneration, and cell death in the in vitro human neuronal and fetal model systems studied. Thimerosal at low nanomolar (nM) concentrations induced significant cellular toxicity in human neuronal and fetal cells. Thimerosal-induced cytoxicity is similar to that observed in AD pathophysiologic studies. Thimerosal was found to be significantly more toxic than the other metal compounds examined. Future studies need to be conducted to evaluate additional mechanisms underlying Thimerosal-induced cellular damage and assess potential co-exposures to other compounds that may increase or decrease Thimerosal-mediated toxicity.

Hepatitis B Vaccination of Male Newborns Causes Autism! Boys Vaccinated At Birth With Hep B Have 3 Times Greater Risk of Being Autistic!

Universal newborn immunization with hepatitis

B vaccine was recommended in 1991; however, safety
findings are mixed. The Vaccine Safety Datalink Workgroup reported no association between hepatitis B vaccination at birth and febrile episodes or neurological adverse
events. Other studies found positive hepatitis B vaccination and ear infection, pharyngitis, and
chronic arthritis; as well as receipt of early intervention/special education services (EIS); in probability samples of U.S. children. Children with autistic spectrum disorder(ASD) comprise a growing caseload for EIS. We evaluated
the association between hepatitis B vaccination of male neonates and parental report of ASD.
METHODS: This cross-sectional study used U.S. probability samples obtained from National Health Interview Survey 1997–2002 datasets. Logistic regression modeling was used to estimate the effect of neonatal hepatitis B vaccination on
ASDrisk amongboys age 3–17 years with shot records, adjusted for race, maternal education, and two-parent household.

RESULTS:Boys who received the hepatitis B vaccine during the first month of life had 2.94 greater odds for ASD (nZ31 of 7,486; OR Z 2.94; p Z 0.03; 95% CI Z 1.10, 7.90)compared to later- or unvaccinated boys.Non-Hispanic white
boys were 61% less likely to have ASD(ORZ0.39; pZ0.04;95% CIZ0.16, 0.94) relative to non-white boys.

CONCLUSION: Findings suggest that U.S. male neonates vaccinated with hepatitis B vaccine had a 3-fold greater risk of ASD; risk was greatest for non-white boys.

State legislations that limit the use of thimerosal in vaccines for pregnant women and their infants

Thimerosal is a mercurial preservative that was widely used in vaccines in the United States and Europe until 2001. By 1999, expanding recommendations for infant vaccinations indicated that United States children who received a complete series of vaccines that contained thimerosal received up to 187.5 μg of ethyl mercury during the first six months of life. This cumulative exposure could exceed the United States Environmental Protection Agency’s recommended safe intake level, estimated in 1997, to be no more than 0.1 μg of mercury per kilogram of body weight per day. This observation lead to a recommendation by the American Academy of Pediatrics that thimerosal is removed to all vaccines that are administered to infants in the United States. Realizing the potential dangers of thimerosal in vaccines, six states have enacted legislations that have limited the amount of thimerosal that can be used in vaccines in their States (Iowa, California, New York, Missouri, Delaware and Washington). In 1987, Congress established the Vaccine Injury Compensation Program to provide compensation to family of individuals who suffer injuries from vaccines. Until recently, these judgments have been paid only to families of non-autistic children who received complications due to the vaccines. In 2008, the Government conceded its first vaccine-autism case in Federal Court. Scientific studies of this autistic child suggested that the autism was related to a mitochondrial disorder. The Federal Government should enact legislation that prohibits the use of thimerosal in vaccines given to pregnant women and their infants.

Sources: Journal of Pediatric Infectious Diseases, Volume 4, Number 3 / 2009.

Is it really accurate to say that thimerosal has been shown to be safe when studies showing the opposite have been published as late as 2009?

Why would the CDC think it okay to give people mercury containing swine flu vaccines when the Journal of Pediatrics says they should be phased out for pregnant women and babies?

It is Safe For Pregnant Women and Children to Recieve a Vaccine Containing Thimerosal

Some priority groups may not be able to find injectable thimerosal-free 2009 H1N1 flu vaccine due to a recent recall of pre-filled, single-dose syringes manufactured by Sanofi Pasteur. Since LAIV is only approved for people from 2 through 49 years of age who are not pregnant and do not have certain health conditions, this means pregnant women and children from ages 6 through 23 months may have difficulty obtaining a thimerosal-free 2009 H1N1 vaccine. Remember, it is safe for children and pregnant women to receive a flu vaccine that contains thimerosal.


They don’t know that because studies have not been done on the thimerosal containing, adjuvanted vaccines:

GSK’s vaccine says this:

‘There are currently no data available on the use of Pandemrix in pregnancy.
There are no safety and immunogenicity data available from clinical studies with Pandemrix (H1N1) in children and adolescents aged from 3-17 years or in children aged less than 6 months. There are very limited data available from a clinical study with Pandemrix (H1N1) in healthy children aged from 6 to 35 months and limited data from a study with a version of Pandemrix containing H5N1 antigens in children aged from 3 to 9 years.

Very limited data in children aged 6 to 35 months (N=51) who received two doses of 0.25 ml (half of the adult dose) with an interval of 3 weeks between doses indicate an increase in the rates of injection site reactions and general symptoms (see section 4.8). In particular rates of fever (axillary temperature GREATER-THAN OR EQUAL TO (8805)38°C) may increase considerably after the second dose. Therefore, monitoring of temperature and measures to lower the fever (such as antipyretic medication as seems clinically necessary) are recommended in young children (e.g. up to approximately 6 years of age) after each vaccination.

There are no data on administration of AS03-adjuvanted vaccines before or following other types of influenza vaccines intended for pre-pandemic or pandemic use.

A protective immune response may not be elicited in all vaccinees.’


Afluria H1N1 vaccine also says:

Pregnancy Category C: Animal reproduction studies have not been conducted with Influenza A (H1N1) 2009 Monovalent Vaccine or AFLURIA. It is also not known whether these vaccines can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Influenza A (H1N1) 2009 Monovalent Vaccine should be given to a pregnant woman only if clearly needed.

Neither Influenza A (H1N1) 2009 Monovalent Vaccine nor AFLURIA has been evaluated in nursing mothers. It is not known whether Influenza A (H1N1) 2009 Monovalent Vaccine or AFLURIA is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Influenza A (H1N1) 2009 Monovalent Vaccine is administered to a nursing woman.’

Getting The Flu Vaccine Is Safer Than Getting The Flu

It is important to keep in mind that severe illness and possible death can be associated with influenza, and vaccination is the best way to prevent influenza infection and its complications. Currently, the 2009 H1N1 flu virus (sometimes called “swine flu”) seems to be causing serious health outcomes for the following priority groups:

* Healthy young people from birth through age 24
* Pregnant women
* Adults 25 to 64 who have certain underlying medical conditions

Children, especially those younger than 5 years of age and those who have high risk medical conditions are at increased risk of influenza-related complications.


According to the NHS, these are the symptoms of ‘swine flu’:

* unusual tiredness,
* headache,
* runny nose,
* sore throat,
* shortness of breath or cough,
* loss of appetite,
* aching muscles,
* diarrhoea or vomiting.

These are the symptoms of regular flu:

* sudden fever (a temperature of 38°C/100.4°F or above),
* dry, chesty cough,
* headache,
* tiredness,
* chills,
* aching muscles,
* limb or joint pain,
* diarrhoea or stomach upset,
* sore throat,
* runny or blocked nose,
* sneezing,
* loss of appetite, and
* difficulty sleeping.

So in actual fact the symptoms are EXACTLY THE SAME as regular flu, and although annoying, the illness is generally mild.

The office of National Statistics also said this:

‘Influenza is often implicated in winter deaths as it can cause complications such as bronchitis and pneumonia, especially in the elderly, although relatively few deaths are attributed to influenza itself. According to the Health Protection Agency (HPA) influenza activity started early and reached moderate levels during the winter of 2008/09, but did not reach the epidemic levels seen in the winter of 1999/2000.’

So actually death rates from influenza illnesses are LESS than in 1999/2000!

The HPA also say in their 31 December 09 report on H1N1, that:

‘The disease is generally mild in most people so far, but is proving severe in a small minority of cases.’

They also say, ‘Data from NHS Direct do not reflect the true pattern of cold/ flu callers and so are not currently an accurate surveillance tool. Deaths – the number of deaths related to swine flu in England as of 17 December is 203 (This figure represents the number of deaths in individuals with swine flu but does not represent the number of deaths that can be attributed to swine flu).’

So the 203 people in the UK reported to have died of H1N1 just happened to be diagnosed with H1N1, which is done without taking any swabs, and their death might not have actually been from H1N1.

So the total worldwide death rate of 12,866 is probably grossly over-reported and even if it wasn’t, that figure is TINY if you consider it is worldwide. Every year in the US there are 36,000 deaths from influenza, respiratory illnesses and cardiac issues so if you add up the numbers, this does not equate to a pandemic and the illness has a lower death rate than many other illnesses.

The Vaccine Side-Effects

As they have not safety tested this vaccine they have no idea what the side-effects are but if we compare with a bird flu vaccine like they are doing, here are the listed side-effects:

Clinical studies have evaluated the incidence of adverse reactions listed below in approximately 5,000 subjects 18 years old and above who received formulations containing A/Vietnam/1194/2004 (H5N1) strain with at least 3.75 microgram HA/AS03.

Blood and lymphatic system disorders

Common: lymphadenopathy

Psychiatric disorders

Uncommon: insomnia

Nervous system disorders

Very common: headache

Uncommon: paraesthesia, somnolence, dizziness

Gastrointestinal disorders

Uncommon: gastro-intestinal symptoms (such as diarrhoea, vomiting, abdominal pain, nausea)

Skin and subcutaneous tissue disorders

Common: ecchymosis at the injection site, sweating increased

Uncommon: pruritus, rash

Musculoskeletal and connective tissue disorders

Very common: arthralgia, myalgia

General disorders and administration site conditions

Very common: induration, swelling, pain and redness at the injection site, fever, fatigue

Common: shivering, influenza like illness, injection site reactions (such as warmth, pruritus)

Uncommon: malaise.

Post-marketing surveillance of H1N1 vaccine – i.e. they only studied the vaccine AFTER they introduced it, as all effects listed above are for H5N1 vaccine, making YOU the experiment!

Immune system disorders

Anaphylaxis, allergic reactions

Nervous system disorders

Febrile convulsions

Skin and subcutaneous tissue disorders

Angioedema, generalised skin reactions, urticaria

Interpandemic trivalent vaccines

From Post-marketing surveillance with interpandemic trivalent vaccines, the following adverse reactions have also been reported:


Neuralgia, transient thrombocytopenia.

Very rare:

Vasculitis with transient renal involvement.

Neurological disorders, such as encephalomyelitis, neuritis and Guillain Barré syndrome.

This medicinal product contains thiomersal (an organomercuric compound) as a preservative and therefore, it is possible that sensitisation reactions may occur (see section 4.4).


Some of the side-effects listed are much worse than the symptoms of the disease, assuming the side-effects are similar to the bird flu vaccine.

Another point is that they cannot say the vaccine is safer when they don’t have any safety data to back up their statement.

Health professionals admitted in their Simpsonwood report 7-8 June 2000, that they have no idea of the accumulative effect of thimerosal in children, that they don’t know what constitutes a safe dose, if any, that they are aware it crosses the placenta and blood/brain barrier. They simply don’t have the knowledge to back up what they’re saying.

They don’t know if children can excrete this so how do they know that 20 years down the line if the child gets cancer, whether it was from his vaccine or not? There are too many unanswered questions.

Research Shows No Link Between Thimerosal And Autism

CDC places a high priority on vaccine safety, surveillance, and research. CDC is aware that the presence of the preservative thimerosal in some vaccines and misconceptions of a relationship to autism has raised concerns. These concerns make the decisions surrounding vaccinations confusing and difficult for some people, especially some parents. Most research done in the United States, and around the world, shows no link between thimerosal in vaccines and autism, a neurodevelopment disorder. In fact, sadly, autism rates have actually gone up since thimerosal was taken out of childhood vaccines in 2001, providing further evidence that thimerosal-containing vaccines are not related to autism.


There are new studies being done frequently which all show a link between thimerosal containing vaccines and ADD, autism, some as late as end of 2009, so clearly it has not been ‘proven’ that thimerosal isn’t implicated in autism. See above for examples.

And it isn’t just an issue with live vaccines like MMR being given after several thimerosal containing vaccines. The issue is with ALL vaccines and has been known about and discussed for years before Dr. Wakefield’s MMR study. For instance, here is a 1976 study implicating smallpox vaccine with autism (known as Kanner Syndrome in those days):

[Autistic syndrome (Kanner) and vaccination against smallpox (author’s
transl)][Article in German]

Eggers C.

3-4 weeks following an otherwise uncomplicated first vaccination against smallpox a boy, then aged 15 months and last seen at the age of 5 1/2 years,gradually developed a complete Kanner syndrome. The question whether vaccination and early infantile autism might be connected is being
discussed. A causal relationship is considered extremely unlikely. But vaccination is recognized as having a starter function for the onset of
PMID: 944354

Source: Klin Padiatr. 1976 Mar;188(2):172- 80

Yes, you read that right, vaccination is recognized as having a starter function for the onset of autism, and that was in 1976!

They say that when thimerosal was taken out of childhood vaccines, autism rates continued to rise, proving that thimerosal couldn’t be related to autism. However, this is factually incorrect.

Thimerosal was never 100% removed from childhood vaccines. It is still present in many vaccines, even the ones labelled thimerosal-free, in trace amounts. See the CDC Pink book for details:

Thimerosal is also still in the Hepatitis B vaccine given to all US neonates at birth (and in some other countries too). A very recent study listed on this page showed that male neonates vaccinated at birth tripled their risk of autism compared with those who weren’t vaccinated!

In addition to this, an annual flu shot was introduced into the US schedule after 2001, and you’ve guessed it, the flu shot contains thimerosal! So it was quite a neat party trick of the CDC to suggest that they’d removed it and autism rates continued to rise, when in actual fact they added it back in via their new recommendations for the flu shot!

Below is a graph showing the US vaccine schedule for 2001:

Source: MMWR, January 12, 2001 / 50(01);7-10, 19.

Now if you look at the graph for 2002, you will see they’ve added in the new thimerosal containing flu shot to be given yearly to selected groups children over 6 months old.

By 2004, this recommendation was extended to everyone over 6 months of age. See for the 2004 graph.

Source: MMWR,January 18, 2002 / 51(02);31-3

The CDC also say:

‘Since 2001, no new vaccine licensed by FDA for use in children has contained thimerosal as a preservative, and all vaccines routinely recommended by CDC for children younger than 6 years of age have been thimerosal-free, or contain only trace amounts of thimerosal, except for multi-dose formulations of influenza vaccine.’


The influenza vaccine they give to babies and children EVERY YEAR and some of the other vaccines still contain trace amounts (that still accumulates).

So it’s no wonder that autism rates have continued to rise!!
