MMR Immunizations Not Linked to Autism

Study Says No Link Between MMR Immunization and Autism

According to a new British study, there is no link between the MMR (measles, mumps and rubella) vaccine and autism as many have speculated.

Dr. Andrew Wakefield raised concerns over the vaccination in 1998 claiming there was an abnormal biological relationship between the two. After he and his cohorts announced their theory, there were noticeable outbreaks of all three diseases in Britain.

To learn about the latest findings,


The current study, released by Archives of Disease in Childhood, re–examined Wakefield's findings by testing 100 autistic children, 52 learning challenged kids, and 90 children who were developing normally. Every child had received the MMR vaccination, but not everyone got both doses.

Dr. Gillian Baird, the pediatrician on the study, said:

"The researchers took blood samples from the children and found no abnormal immune response in any of them marked by higher antibody levels or presence of a measles virus still left in the body from the shot."

A researcher at Britain's Health Protection Agency, David Brown, worked on the study and said,

This study really supports the view these are safe vaccines. The evidence is now so solid there really isn't a need for further studies here.

Did you worry that vaccinating your child could cause autism?

What do you think they replaced the Thimerosal with?? Some other toxic preservative.

there has never been thimerosal in the mmr. (careful where you get your information.) you cannot have a genetic epidemic people. there has to be an environmental factor. also, even though vaccines are no longer made for children with thimerosal, the old vaccines were not destroyed. they are still being used so if you are concerned ask to see the package insert.

My little baby had her MMR today. I am scared of EVERYTHING IN THE WORLD. My heart also goes out to everyone with an autistic child and hope that more understanding of the condition in the future means everyone's lives will be easier.

If the MMR or thimerosal induced autism, then you would expect there to be a lower incidence of autism in children who did not receive vaccinations- this is not the case. The US has not used thimerosal in vaccines since 1999, yet autism numbers continue to rise. The MMR has not been administered as a combo jab in Japan since 1993- yet autism continues to rise there as well. ..Good point.

My daughter had her MMR shots in December. I was scared to death that I was doing the wrong thing and I've been watching for any changes ever since. My heart goes out to the mothers who are dealing with this. As a mother, I believe that I know my child best and if you guys say there is a link, who am I to say otherwise.

That's an interesting website lickety split. It's too bad that other laboratories have been unable to replicate the findings in many of the studies listed on that page, or the authors have retracted their findings, or were published in journals of hypotheses (not even studies, just ideas!) Several years ago, when Generation Resuce ran an ad in the New York Times thanking the scientists who did some of these studies, many of them asked to be removed or otherwise disassociated from the ad. At the time the scientists wrote: ""we believe GenerationRescue’s advertisement, at first appearance an innocuous gesture of appreciation, may actually mislead the public into thinking that the mercury-autism hypothesis has stronger support in the scientific literature than it actually does."" If the MMR or thimerosal induced autism, then you would expect there to be a lower incidence of autism in children who did not receive vaccinations- this is not the case. The US has not used thimerosal in vaccines since 1999, yet autism numbers continue to rise. The MMR has not been administered as a combo jab in Japan since 1993- yet autism continues to rise there as well. Scientists, like me, will continue to do research to understand whole range of important diseases. It's laughable to think that scientists are in it for the money or are magically under the influence of big pharma. If scientists wanted to be rich, most of them wouldn't be scientists. I understand the frustration of parents trying to find answers and trying to find cure for autism- but continuing to ignore science and reason in favor of "personal opinions" and feelings will not get you or future generations of children anywhere.

here is a link to numerous studies regarding autism and environmental factors

Wow I'm actually shocked at how many people aren't taking this study seriously.... and the people who believe Big Pharma is up to no good. I think that's great news =)

I, too, have a child in the autistic spectrum. He was vaccinated per "usual" standards. If I have or adopt more children, they will be vaccinated. I don't blame vaccines for his autism and, while I appreciate this type of research, I think we're too focused on it. It's short sighted to blame autism on one factor, especially something that isn't absolutely conclusive.

As a mother of two children in the autistic spectrum...each of whom have unusually high levels of mercury in their system as well as lead...has anyone taken the time to look at what is actually in a vaccine. We pump our children full of toxins at alarming rates. My son showed no signs of autism until 1 month after his MMR. I do not care what any study says. Why is it that mercury can be put in vaccines at a higher level that what the EPA says can go in a gallon of water. Why are we doing this to our children. We have lost a generation of boys to autism. When is someone going to come up with a treatment or cure for it rather than focus on what is causing it...what is causing autism are the toxins in our environment, our vaccines, our water, our food, etc. So now that our children cant handle it and are autistic...who is going to help us parents with the treatment. The government isnt offering any help but studies. I agree...what good are these studies.

While my heart goes out to parents of children with autism, I think it does a disservice to people with autism to insist that there is some link between autism and MMR when research has consistently shown that not to be the case. If we keep on flogging the same horse, the sparse resources of the scientific community will be wasted proving the same point again and again to people who refuse to listen. The scientists who perform this research are usually not big pharma advocates- they are university researchers who truly want to help people and are not beholden to corporate interests. The Harvard committee (not study) that lickeysplit references did not support Dr. Wakefield's findings. They concluded there was no link between the MMR and autism. A follow up by the Institute of Medicine at the National Academies of Science not only confirmed the finding of the Harvard review, but also indicated that there was no link between thimerosal and autism. The National Academy is made up of independent university professors and they certainly do not answer to Big Pharma. Dr. Wakefield has received hundreds of thousands of dollars to keep on making his disproved claims from personal injury lawyers that are just chomping at the bit to sue hospitals and vaccine manufacturers. In the meantime, parents are given false hope and are still no closer to an answer.

oh, yes, now I am convinced! NOT! The point is that it's not the viruses, it's all the other crap like mercury and preservatives that creates problems. And of course they make a big splash about this, Big Pharma stands to lose a lot of money. Funny how every time someone raises a red flag there is a much-publicized "study" defending... oh look, usually the big guys. What a shock.

Why should one study mean that no further studies are needed? That's a ridiculous way of thinking! If you gave 100 kids peanuts, some would be fine, some would not. Give 100 kids the same vaccine, some will be "fine", some will not. That being said, there are crazy ingredients in these vaccines if you read the actual list. I don't believe the first vaccines were created with bad intentions. I do believe the drug companies have taken advantage of all the new tiny patients (customers?) in this world. They are given too many in such a small time frame (sometimes 5 in ONE doctors visit!). I decline vaccines for my children.

I think there are inherited genetic triggers that can be set off by a vaccine, meaning that children with autism are somehow genetically predisposed. So the austism isn't caused by the vaccine but rather triggered...but that is a personal opinion and I think like most neurological problems, more research needs to be done.

as the mother of a child with autism (caused by vaccines), someone who has spoken with dr. wakefield, and the mother of 2 typically developing children let me pass on a few things to think about. 1) without exception every doctor i have spoken with in the last 6 years who is younger (under 35) believes there is some kind of connection between autism and vaccines. this includes doctors at stanford university and ucla. not saying all doctors at these institutions, but the ones i have spoken with. they are choosing not to vaccinate their children on the schedule recommended by the american academy of peds. for example, they don't give more than one jab at a time (no htp or mmr), they give the vaccines selectively (not everything needs to be vacinated against) and they vaccinate later (measels vaccination at 4 years rather than 15 months), and they run a titer (test the antibodies and imunity) before giving a second or third jab because the child might not need further vaccines. much of the vaccinating in this country is done at an early age because the kids are in the doctors offices for those early check-ups and the medical community wanted to ensure they got to as many children as possible. 2) the doctors who changed their minds about the original study were basiclly forced into doing so. i believe harvard duplicated the original wakefield study a few years ago with similar results. i'll see if i can find the link and post it here. 3)i lived this. i can tell you what happened at my house and it's enough that all of our friends and family members have changed the way they vaccinate their children and themselves. not everyone responds the same way to vaccines. maybe you'll be lucky and maybe you won't. what is the hurt in being cautious and running a titer at the very least? once done the harm cannot be reversed.

I think there needs to be a study on epidurals next. Of course it won't happen because people make so much money on them.

It's important to note that in addition to the recent research presented here, the conclusions of the 1998 Wakefield paper were retracted by 10 of the 13 authors of the paper. The paper only involved 12 sample subjects and did not establish any causal link between the MMR and autism.
