This is an excellent article by Arindam which explores the controversial subject of Autism and the MMR Vaccine.
Do MMR Vaccines Cause Autism?
By Arindam Chattopadhyaya
Autism is a neurological disorder; observable symptoms of this disability include disruption of speech, difficulty in social exchanges, and demonstration of consistent behavior. There are lots of arguments on this disorder regarding a possible link between vaccines and autism. The MMR (mumps, measles, and rubella) vaccines are prime suspect for autism. It appears that the number of diagnosed cases of autism increases since the inception and use of MMR vaccine.
Medical Scientists and statistician collected lots of data and information to find the relation between MMR vaccines and autism. Two considerations regarding the debate over vaccines and autism are the claim of increased cases, and the results of studies that evaluated a possible correlation between vaccines and autism.
Do increased Cases of Autism mean Conclusive Evidence?
A report on similar study in the State of California suggests a possible correlation between vaccines and autism. The report hints at a marked rise in cases of autism and correlates this increase with an increase in the MMR vaccine being administered. However, the argument can be made that it’s important to take into account other data trends within this time frame.
For example, it’s important to note that even though there was a rise in diagnosed cases of autism there was also a corresponding rise in the population. The argument could be made that an increase in population alone would increase the number of diagnosed cases of autism. In addition, awareness and education initiatives may be factors that led to the early diagnosis of autism in children, which has resulted in an apparent increase in the number of cases.
What’s the conclusion of Medical Society?
A number of studies have been conducted from the mid-1970s to the present time to ascertain any correlation between the administering of vaccines and autism. In addition these studies have been conducted in various countries, researching different variables of the vaccines and autism, as well as by several different research entities.
One study examined the incidences of autism before and after the use of MMR and found no variations. Another study focused on the vaccine itself and found no evidence to substantiate the triggering of autism by MMR. In addition, an additional study looked at autistic children. This study determined that the age of diagnosis was the same whether the MMR vaccine was administered prior to or after 18 months of age.
Studies Suggesting a Correlation – Or Not
There are studies that have been conducted that suggest a relationship between vaccines and autism. These studies imply that the digestive system is affected by a viral infection introduced by the MMR vaccine can lead to autism. Unfortunately, the majority of the studies were suspect when other researchers were unable to reach the same conclusion, showing that the methods of research were flawed. However, one study conducted in 2002 showed a possible link between the MMR vaccine and a developmental disorder. This particular study did go on to say, however, that the reverse could be true in that the developmental disorder caused the viral infection.
Vaccines are doing well to public health by arresting some critical diseases. Till today, no conclusive medical evidence has been proven. This is the most favorable arguments in favor of vaccine safety.
