Some parents blame vaccine as cause of their son’s autism most specially the MMR vaccine. They claimed that their child is reaching their milestone not after the MMR vaccine. They told that after vaccine, their child lost all the language acquired and regressed that no longer had skills capable of even a month previous. Other told that their child has learning disabilities after receiving a series of vaccines.
There are many cases that a child became autistic after vaccination that is why many studies were performed as whether vaccines cause autism. Also, There are hypotheses that have been proposed by some researcher, they said that the combination of measles-rubella vaccine causes autism because it damages the intestinal lining which allows the entrance of encephalopathic proteins. Also, it has thimerosal, an ethyl mercury containing preservatives in some vaccines, that is toxic to the central nervous system. In addition, the simultaneously admiration of multiple vaccines overwhelms or weakens the immune system.
After several studies, there is no complete evidence that vaccines cause autism. Each study has come up empty. Last 2004, the Immunization Safety Review Committee of the Institute of Medicine published a 200-page report stating that there was no evidence to support a link between autism and vaccine. The findings are based on scientific evidence that vaccine do not cause autism.
As of now, there is no complete evidence presented that vaccines linked to autism.
