Could Childhood Vaccinations Lead To Autism?


A 1998 study that had people thinking autism is caused from an often-used childhood vaccination has been debunked again.

After an article in the British Medical Journal said the study was fraudulent, researchers who previously said that the vaccine theory was nonsense got busy unveiling credible causes of the developmental disease. Autism strikes one out of every 110 children born in the United States, and studies have indicated previously that 90 percent of autism cases might be genetic in origin. But an ever-increasing number of autism researchers now think autism isn’t simply genetic-based, but also involves factors like the relationship between genes and environmental exposures.

“It’s unquestionable that there’s a genetic component, but on the other hand, it’s becoming equally clear that genetics is not the only culprit,” said pediatrician Phil Landrigan, MD, MSc, director of the Children’s Environmental Health Center at Mount Sinai Medical Center.

Linda Birnbaum, PhD, director of the National Institute of Environmental Health Sciences, restated the importance of comprehending the notion that environmental factors don’t just indicate industrial and agricultural chemicals, but also agents such as radiation, drugs, and food– not to mention socioeconomic factors and perhaps even microflora in our stomachs. All of these factors respond in different ways to environmental compounds.

The things that cause autism, researchers believe, could be a variety of separate environmental exposures like these.

In 2010, the Lancet journal retracted the controversial study connecting the MMR (measles, mumps, and rubella) vaccine to causation of autism after more and more scientific studies were unable to duplicate similar results in their own findings.

So then what does cause autism? According to a contemporary article published in the journal Current Opinion in Pediatrics, the greatest strength of evidence supports the belief that environmental exposures typically lead to the onset of autism. With that being said, the harmful exposure implied usually takes place during the first trimester of mothers of autistic childrens’ pregnancies.
