Autism Linked to Vaccines, as Study Finds Fast-Growing Number of Autistic Children

Oct 06, 2009
The recent report published in the journal Pediatrics says that 1 in every 91 children in the United States have an autism disorder. This rate is more than 50 percent higher if compared to the numbers in 2003.

The survey conducted by the Department of Health and Human Services National Survey of Children's health revealed that almost 110 out of every 10,000 parents said that they have a child diagnosed with autism. Overall, as much as 78,000 respondents took part in the study.

Autism spectrum disorder is developmental disorder characterized by the repetitive behavior, communication difficulties and social interaction problems. This long-term condition affects a person's life in many aspects, making it difficult for a person to live and work independently. 

Recently many parents are concerned about the possible link between vaccines and autism. A new study conducted at the University of Pittsburgh showed that vaccine can indeed affect brain development in a negative way. Scientists found that infant macaque monkeys, who were given Hepatitis B vaccine, containing thimerosal chemical, experienced a serious delay in developing vital reflexes. The monkeys, who were not vaccinated, did not have the developmental delay.

Thimerosal, is a chemical made with methyl mercury, is known to be toxic to the nervous system. The chemical was removed from the Hepatitis B vaccine in 2000, but children were given the vaccine with thimerosal until 2002 and it is said to be present in other vaccines, including the seasonal flu and H1N1 vaccine. Scientists say that the introduction of the vaccine is associated with the significant increase in autism. Other chemicals such as squalene in the vaccines are known to affect the nervous system in a negative way.

The study was published in the journal NeuroToxicology.
