Autism cases 'levelling off'

"The controversial MMR vaccine has not triggered an increase in the number of children being diagnosed with autism, according to experts.

Researchers at University College London say figures actually show that the number of new cases has levelled off and may have peaked 11 years ago.

They also said that the rise in new cases throughout the 1980s and early 1990s may have been simply due to greater awareness of the condition.

Nevertheless, the study found that parents were now more likely to blame their children's autism on the MMR vaccine.

New cases

Professor Brent Taylor and colleagues at UCL identified 567 children born between 1979 and 1998 who were diagnosed with autism in north-east London.

They found that the number of children being diagnosed with autism peaked in 1992.

" The appearance of autism appears to have stabilised "

University College London researchers

They reported that the number of new cases levelled off between 1992 and 1996, with between 45 and 50 children being diagnosed with the condition.

This was equivalent to 2.6 cases for every 1,000 live births.

The researchers said that if autism was caused by the MMR vaccine then figures would have jumped sharply throughout the early 1990s. The MMR vaccine was introduced in Britain in 1988.

But writing in the journal Archives of Disease of Childhood, the researchers said: "The appearance of autism appears to have stabilised."

They researchers also dismissed claims that the vaccine can cause developmental or bowel problems in children.

"The claims that MMR vaccine is involved in the initiation of autism, and/or with regression, and/or with bowel problems associated with autism are not supported by any credible scientific evidence, while there is compelling and increasing evidence showing no association."

The researchers said controversial research published in 1997, which suggested a link between the MMR vaccine and autism, appeared to have influenced parents.

Before the study was published, just two out of 46 parents had suggested the vaccine had caused autism in their child.

However, afterwards it was cited in six out of 30 cases.

"Before August 1997, parents incriminated trigger factors such as domestic stress, seizures or viral illness.

"Post 1997, parents were more likely to attribute regression to vaccination, especially the MMR vaccine," the researchers said.

The UK's National Autistic Society welcomed the study.

Stuart Notholt, its director of policy, said it was difficult to get accurate figures on the incidence of autism.

"Data on the numbers affected by autistic spectrum disorders continue to be sparse and it has been difficult to compare current numbers with figures from earlier years," he said.

However, he said the number of new cases could be expected to level out if doctors were becoming more aware of the condition and if there was no external cause, such as a vaccine.

"It might be expected that with growing familiarity with autistic spectrum disorders, over a period of time, provided there were no external factors influencing onset, prevalence figures would begin to level out."

Without having read the entire article, I did notice the comment on AUtism peaking in 1992. Isn't that the year the FDA ordered the PC's to stop putting thermisol/mercury in the vaccinations? I know I'm not explaining it right, but I thought it was 91' or 92' that they finally admitted that it(mercury) was not a good thing in even small doses and not needed anymore. Am I totally off on this? I wish I could find the article I was reading, but if so, that would totally make sense. Especially if the PC's are just taking it out slowly, as to not make it obvious????? Then we would see a decrease, but not abruptly right?

The recommendation for thimerosal removal was made around 1997, I believe. The levelling off of autism cases started well before the removal of thimerosal.

Eve, I hope you are not two years out of sync with your other information...

You are confusing the date of the request to remove mercury w/the date of the "Modernization Act of 1997" that only called for a review of products containing mercury.

The Food and Drug Administration (FDA) Modernization Act of 1997 called for FDA to review and assess the risk of all mercury-containing food and drugs.

Over a year went by before the FDAMA mercury study got any public attention at FDA. Finally, on December 14, 1998, just 11 months before the congressional deadline, the agency published a notice in the Federal Register requesting manufacturers to provide data on mercury content. The agency published a second, more specific request on April 29, 1999.

It wasn't until mid 1999 that the request to adjust the mercury came out,

July 09, 1999 / 48(26);563-565

http://www.cdc.gov/epo/mmwr/preview/mmwrhtml/mm4826a3.htm

"As a result of these concerns in the United States, the American Academy of Paediatrics and the U.S. Public Health Service issued a joint statement in July 1999, recommending that the removal of thimerosal from vaccines be accomplished as soon as possible(3)."

So the autism cases levelled off WAAAAAAYYYYY before the removal of thimerosal. YEars, in fact. Interesting.

LOL - good one Christine. I stated that my memory was a bit fuzzy wrt exactly which year it was but your point only proves even more that thimerosal removal was VERY far removed from the noted autism rise and fall. Thanks for further proving my point.

What does the mercury amounts in US vaccines have to do with autism in the UK? What was the mercury content of the vaccines used in the children studied?

It was a question posed by a new poster (trekgirl007) about the FDA's recommendations. I have no idea why the question was posed. Another good point (you're on a roll) - it DOESN'T have anything to do with autism in the US let alone in the UK and there IS no mercury in the vaccine referred to in the article - the MMR vaccine. Thanks again Christine.

Well, there are traces of mercury in the MMR, but apparently not enough of it to warrant including it on the insert info. Would still be interested to know the mercury content of the vaccines the children in the study received before getting the MMR. One of the theories re: autism and vaccines, is that the mercury set the system up, and the MMR finished it off.

That's such a tired old song and dance Christine. There is no mercury in the MMR vaccine and never has been. Even the most staunchly anti-vax will actually concede to this. If the theory holds that mercury is the set up and mmr is the trigger, then this evidence shows that mmr is NOT the trigger and casts this entire theory into doubt.

I would say you are wrong,

"I have Boyd's testing results and there is mercury in MMR. He did not find as much as what was in Hib, Hep B and DTaP. However, IT IS THERE. Whether this is problematic since it may be acting to kill the live virus which makes the vaccine more dangerous is open for debate. Also, my son got MMR and Hib at the same time so he did get mercury from the Hib and MMR combined. Nonetheless, the mercury in the MMR may be acting to depress the immune system and to boost the immune system to an unacceptable level in some children so they actually get the measles like my son. If you want any additional information let me know.

It is in there believe me. We sent samples to Boyd Haley's laboratory and he detected it. It is not disclosed because it is used in the "manufacturing process" and is not used as a "preservative".

Maybe Dr Haley could provide you the evidence you deny.
