Do MMR Vaccines Cause Autism?
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 has increased since the inception
and use of MMR vaccine.
Medical Scientists and statisticians 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 are 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.
