What is the correlation between immunization and autism?
The correlation between immunization and autism has been written an incredible amount. Many parent groups strongly feel that some immunization may be responsible for autism cases. This strong feeling and parental activism has repeatedly led to the demand for research and clinical research suggests that there is no link between immunization and autism. The medical community stands directly against the established tie and even the courts were involved and issued a decision in 2010 that there was no connection.
One of the strongest studies that indicated the link between immunization and autism was published in the respected medical journal, The Lancet in 1998. Its presence has created a fiery interest, especially among parents, as and a growing degree of autism, and many defended abandoning. Doctors who have felt the risk of infection of serious illnesses are still oftenEM higher than the risk of obtaining autism did not support this choice.
For a moment, focusing in the defense of parents in some vaccines called Thimerosal. It was assumed that it increased the risk of autism, according to the Lancet and other sources. This matter was also explored and Thimerosal was removed from most of the vaccination. At present, according to medical and court standards, this chemical is not responsible for cases of autism, and especially measles, mumps and railing (MRD), which was considered to be the likely cause of autism of parental lawyard groups, is not considered to be a relationship to illness. The exception is that the first symptoms of autism may occur at about the same time as the MRD is given, which is the case if children actually receive a vaccine.
Recent research on this disease suggests a minor connection between immunization and autism and more relation to genetics.An extensive study invested in the manifestation of the large organization Autism, evaluated more than 2000 children to see if there were genetic factors that predetermine people for autism, and it turned out to exist. They are simply not free, but include small defects or differences in many different genes. It is clear that the condition is not responsible for a single gene, but people can have a number of genes that more predict the occurrence of autism.
With all these evidence, correlation between immunization and autism cannot be completely excluded in all cases. Certain factors argue against this. Immunization levels have now dropped over the fear that autism is caused by vaccines, yet the levels of autism are still growing. Autism occurs in boys with much greater frequency than Girls, but both sexes are vaccinated the same.
The legitimate science could not prove the correlation between immunization and autism. Most of the evidence indicating the connection is provided by medical laymen and is not supported by hard science. Virtually all legitesMen medical organizations will refute the connection and express deep concern about the possible dangers of avoiding vaccination.
