Vaccines and Autism - Science Says They Are Unrelated
Scientific Raptor, 22/6/2016.
Vaccines and autism is in the news again. Probably as a result of reports that more and more children are being diagnosed with autism spectrum disorders. So let’s take a look at the science.
On 28 March 2014, the United States Centers for Disease Control and Prevention (CDC) announced that new data show that the estimated number of children identified with autism spectrum disorder (ASD), a disorder of neural development, usually appearing before the age of 3 years, characterized by impaired social interaction and verbal and non-verbal communication, and by restricted, repetitive or stereotyped behavior, continues to rise. The picture of ASD in US communities is changing.
CDC study– autism spectrum disorder rates
According to the study:
About 1 in 68 children (or 14.7 per 1,000 8 year olds) were identified with ASD. This data was culled from studies on 8-year-old children living in 11 communities across the country. The data was gathered in this manner to get a detailed analysis of representative subsection of the USA, but it does not statistically represent the entire population of children in the United States.
This new estimate is roughly 30% higher than the estimate for 2008 (1 in 88), roughly 60% higher than the estimate for 2006 (1 in 110), and roughly 120% higher than the estimates for 2002 and 2000 (1 in 150). We don’t know what is causing this increase.
