Meta Analysis on a Million Kids Shows No Link Between Vaccines and Autism


A new meta analysis study on 1.25 million kids shows no link between vaccines and autism. The study is the largest ever performed and the results were just released this week. This latest data adds to a huge body of scientific evidence that has already proven that vaccines do not cause autism. However, as the measles epidemic continues to grow because of the anti-vaccine movement, the CDC is concerned that a new massive study such as this one will do little to sway parents who have made up their minds that there is a link between vaccines and the dread disease.

Besides the missing link between vaccines and autism, the study has also proven that there is no link between mercury and thimerosal and autism. Some of the people who believe that there is a link attribute the causal agents as being mercury or other ingredients found in the vaccines. However, science has now shown that this is not the case.

The myth that vaccines cause autism began in 1998, when a doctor who has since been formally stripped of his medical license published a fraudulent study that showed a link between vaccines and autism as well as autism spectrum disorder. That doctor was found guilty of falsifying the results and the study was completely retracted by the original journal that had been duped into publishing it.

What’s more, say researchers, the new meta analysis on over a million kids shows not only no link between vaccines and autism, but it actually shows a reduced risk of autism in children who have gotten the measles, mumps and rubella vaccine, also called the MMR vaccine. The study was massive and very well-controlled, even examining each of the sub-studies and evaluating them for possible bias. Additionally, the authors of the new study state that they have no conflicts of interest and are objective observers. The study has been published in the peer-reviewed journal Vaccines. Despite these findings, one out of four parents still believes that vaccines can cause autism and a host of other health complaints.

Celebrities like Jenny McCarthy, Alicia Silverstone and Kristin Cavalari have done much to promote the idea that parents should not vaccinate their children. McCarthy, in particular, has been vocal in her anti-vaccine stance and says that she believes her son’s diagnosis of autism was due to the vaccines he received.

While this new study is the largest of its kind and supports an extensive body of established research in this field, other studies have shown that the more pro-vaccine information is given to the public, the more the vaccine doubters resist the science behind the discussion. In fact, a study recently published in the journal Pediatrics showed that pro-vaccine information tended to strengthen the beliefs and fears of the people who believe that there is a link between vaccines and autism.

Some experts say that this is indicative of a trend toward science denial in U.S. society recently. The most common areas of science denial include climate change, evolution and vaccines. Sociologists point to the phenomena of motivated reasoning and the need to constantly reinforce the sense of self and individual beliefs as reasons for denying things supported by a large amount of scientific evidence.

A new meta analysis on over a million kids shows no link between vaccines and autism. As the measles epidemic continues to increase, public health officials have been ramping up their efforts to convince parents of the safety and efficacy of vaccines.

    If anyone thinks this type of study can be done on Autism you are completely lost is space. 1.25 million shows no link is impossible unless it was done by the CDC or the drug companies. The simple fact that there are vaccine injury courts is all you need to know this study is a fake.

    “Dr.” J. Smythe, you have no idea what “scientific theory” means, do you? Do you think you have some kind of magical window into objective truth, as you dismiss empirical evidence as somehow beneath you?

    You’re a crackpot.

    “Science denial”? Look at who came up with that term, sociologists. There’s a valid science for you… Based on the concepts of political correctness and the denial of objective truth.

    Then they use the concepts of “global warming” and “evolution” – both of which have been scientifically disproven, so they try to use the term “climate change” and Darwinian evolution is just touted as “fact” even though it is nothing more than a mere theory. A theory that if questioned those who do so are merely ridiculed to help shame them back into the status quo.

    Whatever happened to true critical (criterion based) thinking … ?

    That’s right, that went out when subjectivism became the fad.

    Its a review of all the previous fake research that the drug companies are trying to shove down our throats and we are suppose to bow down and agree, what a joke, and they wonder why no one trusts them and why everyone is refusing vaccines.

    We should stop worrying about the children, let’s worry about those mercury poisoned dolphins in Port Phillip who unlike our wandering children that find water and drown, the dophin’s are exhibiting poor health ,brain damage and are beaching themselves. “Researchers from the School of Biological Sciences have confirmed levels of mercury found in the dolphins were within a range considered to cause negative health and mental effects and were higher than mercury levels found in populations around the world.’ Children are just pawns in a pharmaceutical game, we can save the whales and dolphins, and should get on it!!

    A meta analysis is not a study. It is combining the results of similar studies. When we are provided with the link to the full text, then we will see if it is valid.
    “The decision about whether or not the results of individual studies are similar enough to be combined in a meta-analysis is essential to the validity of the result” – Cochrane Collaboration

    Really.. They really went and spent all that time trying to prove something which is already a scientific fact. I have very little sympathy for the anti-vaccine morons. if they dont want to vaccinate their kids out of some voodoo beliefs they have about vaccines, feel free to do so, but dont send your kids to school, hospitals or to other areas where small kids or old sick people are. Dont infect the world with your selfishness.

    Outstanding defense of science-based medicine. Brilliant article, Rebecca! The capacity of the human race for willful ignorance based on fear and misinformation is truly something, is it not?

    Wow what a shocker. Anybody who has published data showing a link has had their medical license pulled. There is no unbiased research in this area. I personally have been injured by a vaccine when I was two years old. And it still affects me 34 years later these things are dangerous. I don’t believe this, I know this from self-experience unfortunately :-(. I wish I didn’t.
