MMR Vaccine, Thimerosal and Autism

Updated again 8 September 2014:

“This Autism General Order #1 is being issued by the Office of Special Masters (“OSM”), to address an unusual situation facing the National Vaccine Injury
Compensation Program (“Program.”) …..autism, or neurodevelopmental disorders similar to autism, may be caused by Measles-Mumps-Rubella (“MMR”) vaccinations; by the “thimerosal” ingredient contained in certain Diphtheria-Tetanus-Pertussis (“DTP”), Diphtheria-Tetanus-acellar Pertussis (“DTaP”), Hepatitis B, and Hemophilus Influenza Type B (“HIB”) vaccinations; or by some combination of the two.

here in full at Autism General Order from Various Petitioners vs Health and Human Services, July 3, 2002.

I have added bold type to show how the MMR and thimerosal  may cause autism.  “over 400 cases alleging a causal relationship between such vaccinations and autism disorders have been filed in this court; more than 300 of those cases have been filed in the past six months.” This was dated in July 2002. By May 2009 ” approximately 5,000 autism claims that have been filed under the Vaccine Act

An article in journal Pediatrics  “sheds further light on the relationship between autism and gastrointestinal problems” with the MMR vaccine. The MMR vaccine and weakens the immune system so when other vaccines containing thimerosal are given there

see in the Appeals Court Cedillo vs Health and Human Services (HHS), here, Hazelhurst vs HHS here

Updated August 2014: According to the FDA Thimerosal was never used in MMR vaccines. If so then why is there all the mention of Thimerosal?

Is the 2004 CDC case-control study published in Pediatrics the whole story about the relationship between MMR and Autism? There is no thimerosal in the MMR vaccine if I am reading online correctly. It must be something else. I have more questions though: in early childhood children get a variety of vaccinations, why has the MMR vaccination been isolated as the cause of the Autism? What is in the vaccine that is the cause of the link with Autism? Has it been removed already? When was it first noted? Have you read the study in Pediatrics?  I seem to have more questions than answers.

“A February 2004 case-control studyExternal Web Site Icon examined the possible relationship between exposure to the MMR vaccine and autism in Atlanta, Georgia. The results were published in Pediatrics.

Pay US$12 and read the 2004 case-control study results clicking the link below:

“The MMR vaccine does not contain any preservatives or adjuvant.
Preservatives and adjuvant (most commonly aluminum) cannot be
used in vaccines containing live viruses because these chemicals
would inactivate the vaccine and render it useless. The MMR vaccine
never contained any thimerosal preservative.”

from Components of the MMR Vaccine by Leslie Young, M.D.

“Why was thimerosal removed from vaccines given to children?
Although no evidence suggests that there are safety concerns with thimerosal, vaccine manufacturers have stopped using it as a precautionary measure.The only vaccine that still includes thimerosal as a preservative is the multi-dose inactivated influenza vaccine. There are other formulations of flu vaccine that do not include thimerosal.
In 1999, the Food and Drug Administration (FDA) was required by law to assess the amount of mercury in all the products the agency oversees, not just vaccines. The U.S. Public Health Service decided that as much mercury as possible should be removed from vaccines, and thimerosal was the only source of mercury in vaccines.
The decision to remove it was a made as a precautionary measure to decrease overall exposure to mercury among young infants.
Thimerosal was removed from all childhood vaccines in 2001 with the exception of inactivated flu vaccine in multi-dose vials. However, thimerosal has been removed from all single-dose preparations of flu vaccine for children and adults. There has never been thimerosal in live attenuated flu vaccine or recombinant flu vaccine. No acceptable alternative preservative has yet been identified for multi-dose flu vaccine vials.”

This is not breaking news but I was reading a recent post here on John Rappoport’s blog so I decided to research for myself and I found a Forbes article dated March 2014 here then I stumbled upon news here at Age of Autism about the link between mercury in vaccines and autism.

Research articles about The Science on Autism, Mitocondria and Mercury found here at
SafeMinds was founded to raise awareness, support research, change policy and focus national attention on the growing evidence of a link between mercury and neurological disorders.

“We believe that autism is the defining disorder of our age, man-made and therefore preventable, and that it points to the truth about other problems that beset us, from ADD to asthma to Alzheimer’s. We address those issues as well, along with exposing the special interests, bureaucratic inertia, and medical malfeasance that perpetuate denial and suffering.”
from letter from the editor at Age of Autism

The Age of Autism: Mercury, Medicine and the Man-Made Epidemic by Dan Olmsted and Mark Blaxill, published 2011
*I haven’t read the book. I include this to add evidence that this topic is not new.

Thimerosal/Thiomerosal and Vaccines

It would appear that thimerosal/thiomerosal is NOT used in MMR vaccines worldwide but it is possible to be present in multi-dose vaccines such as the flu/influenza vaccine.

“Thimerosal is a mercury-containing preservative used in some vaccines and other products since the 1930’s. There is no convincing evidence of harm caused by the low doses of thimerosal in vaccines, except for minor reactions like redness and swelling at the injection site. However, in July 1999, the Public Health Service agencies, the American Academy of Pediatrics, and vaccine manufacturers agreed that thimerosal should be reduced or eliminated in vaccines as a precautionary measure. ”
from CDC

“Since 2001, all routinely recommended vaccines (except for the flu vaccine) for administration to young children in the U.S. contain no thimerosal or only trace amounts.
Vaccines with trace amounts of thimerosal are labeled “preservative-free.
Vaccines that do not contain any thimerosal are labeled “thimerosal-free.
from Minnesota Department of Health

“Is thimerosal in all vaccines?
No. Most vaccines licensed in Canada do not contain thimerosal.
The influenza vaccine and most hepatitis B vaccines are multi-dose vaccines, which contain thimerosal as a preservative.
For immunization of infants against hepatitis B, parents or guardians in some provinces and territories have the choice of a thimerosal-free vaccine.”
from Public Health Agency of Canada

“In Australia, thiomersal has been removed from all routine childhood vaccines since 2000. The exception is one type of hepatitis B vaccine which contains a greatly reduced amount of thiomersal.”
from National Centre for Immunisation Research & Surveillance

New Zealand
“Does the MMR vaccine contain thiomersal (or mercury)?
Answer: No. National Immunisation Schedule vaccines used in New Zealand, including MMR, do not contain thiomersal (also known as thimerosal).
Last updated: 20-03-2012”
from Immunisation Advisory Centre, the University of Auckland

United Kingdom
Does the MMR jab contain thiomersal?
No, the MMR vaccine has never contained thiomersal – a preservative containing mercury that is used in some vaccines.
from National Health Service

European Union
“The Committee for Proprietary Medicinal Products (CPMP) previously advised that although there was no evidence of harm from thiomersal in vaccines other than hypersensitivity (allergic) reactions, it would be prudent to promote the general use of vaccines without thiomersal and other mercury containing preservatives, particularly for single dose vaccines. Since then, several vaccines licensed in the European Union have had thiomersal removed or levels reduced and new vaccines without thiomersal have been licensed. CPMP advice was in line with the global goal of reducing environmental exposure to mercury. The previous assessment of risks associated with ethylmercury had been based on data on methylmercury, as the toxicity profile of the two compounds was assumed to be similar.”
from EMEA, The European Agency for the Evaluation of Medicinal Products
