Autism may run in the family and researchers have looked at whether vaccines can make autism more likely in children who have autistic siblings.
Researchers have found out vaccines have no autism risk, whether or not a member of the family was diagnosed or not.
A study, led by Dr. Anjali Jain, in Falls Church, Virginia reported, ‘Consistent with studies in the population, there is no association between MMR vaccination and increased ASD risk among privately insured children.
We also found no evidence that receipt of either one or two doses of MMR vaccination was linked with an increased risk of ASD among children who had older siblings with ASD.’
Autism is rising, with about 1 in 68 children in the United States has autism, though the cause remains a mystery.Because of a published 1998 article written by Andrew Wakefield purportedly linking the MMR vaccine with autism in 12 children, the fear of the vaccine and autism has escalated.
But, it was found later to be untrue and was recanted by the publisher of the journal. And the author, Wakefield was later divested of his medical license.
But anxieties over the vaccine safety, mostly in the new age of the world wide web, have been difficult to quell.
The JAMA study said, ‘Although a substantial body of research over the last 15 years has found no link between the MMR vaccine and ASD, parents and others continue to associate the vaccine with ASD.’
A survey of parents who have children with ASD suggest that many believe the MMR vaccine was the root cause. Children who have other siblings with autism are less likely to get vaccinated, the study discovered.
MMR vaccination for children with unaffected siblings was 92 % at the age of five.
In comparison, the MMR vaccination rate for children with older siblings with ASD is 86 % by the age of five.
An editorial by Dr. Bryan King, of the University of Washington and Seattle Children’s Hospital, said the data is distinctly clear.
“The only conclusion that can be drawn from the study is that there is no signal to suggest a relationship between MMR and the development of autism in children with or without a sibling who has autism.“
