It’s official, a real study confirms that vaccines are NOT linked to autism

The pseudo-scientific argument that vaccines cause autism is based on very poor science and questionable motives. A new study out of the Children’s Hospital Medical Center in Cincinnati, OH further confirms that there is no scientific basis for believing that vaccines are a causative factor in the development of autism. Unlike the “work” by the much maligned Andrew Wakefield, this study actually looks at a large enough group of children to draw meaningful conclusions. Vaccines do not cause autism, please get your children vaccinated. You are putting your child at risk, and not vaccinating your children is a major threat to public health.

Excerpts from:

Number Of Early Childhood Vaccines Not Linked To Autism” by Jon Hamilton

The study offers a response to vaccine skeptics who have suggested that getting too many vaccines on one day or in the first two years of life may lead to autism, says Frank DeStefano, director of the Immunization Safety Office of the CDC.

To find out if that was happening, DeStefano led a team that compared the vaccine histories of about 250 children who had autism spectrum disorder with those of 750 typical kids. Specifically, the researchers looked at what scientists call antigens. An antigen is a substance in a vaccine that causes the body to produce antibodies, proteins that help fight off infections.

The team looked at medical records to see how many antigens each child received and whether that affected the risk of autism. The results, published in The Journal of Pediatrics, were unequivocal.

“The amount of antigens from vaccines received on one day of vaccination or in total during the first two years of life is not related to the development of autism spectrum disorder in children,” DeStefano says.

The Risk of Autism Is Not Increased by “Too Many Vaccines Too Soon”

Although scientific evidence suggests that vaccines do not cause autism, approximately one-third of parents continue to express concern that they do; nearly 1 in 10 parents refuse or delay vaccinations because they believe it is safer than following the Centers for Disease Control and Prevention’s (CDC) schedule (http://www.cdc.gov/vaccines/parents/downloads/parent-ver-sch-0-6yrs.pdf). A primary concern is the number of vaccines administered, both on a single day and cumulatively over the first 2 years of life. In a new study scheduled for publication in The Journal of Pediatrics, researchers concluded that there is no association between receiving “too many vaccines too soon” and autism.


The researchers determined the total antigen numbers by adding the number of different antigens in all vaccines each child received in one day, as well as all vaccines each child received up to 2 years of age. The authors found that the total antigens from vaccines received by age 2 years, or the maximum number received on a single day, was the same between children with and without ASD. Furthermore, when comparing antigen numbers, no relationship was found when they evaluated the sub-categories of autistic disorder and ASD with regression.

Although the current routine childhood vaccine schedule contains more vaccines than the schedule in the late 1990s, the maximum number of antigens that a child could be exposed to by 2 years of age in 2013 is 315, compared with several thousand in the late 1990s. Because different types of vaccines contain varying amounts of antigens, this research acknowledged that merely counting the number of vaccines received does not adequately account for how different vaccines and vaccine combinations stimulate the immune system. For example, the older whole cell pertussis vaccine causes the production of about 3000 different antibodies, whereas the newer acellular pertussis vaccine causes the production of 6 or fewer different antibodies.

    Write more, thats all I have to say. Literally, it seems as though you relied on the
    video to make your point. You clearly know what youre talking about,
    why waste your intelligence on just posting videos to your site when you could be giving us something informative
    to read?

      First, there is an overwhelming body of evidence that vaccines have absolutely no connection to autism. It’s easily searchable by google if you want reading material.
      Second, this post is well over a year old, there have been lots of studies since then that continue to prove there is no link between autism and vaccines.
      Third, I’m not sure what video you are talking about? This post is all text, as is the previous post about the same topic.
      The blog is undergoing some updating and should be posting interesting content regularly.
