Peggy Halliday discusses a variety of topics related to autism spectrum disorders, such as if there's any evidence that autism can be linked to certain vaccinations
Host: Is there any evidence that autism can be linked to certain vaccinations? Peggy Halliday: Research has not shown a link between autism and vaccine. This is then a huge cause of concern for parents because we are giving our children so many vaccinations these days. The MMR vaccines, the measles, mumps and rubella, was originally thought perhaps to have a link between vaccine and autism because it is given to children at about the same age as some of the symptoms start to show up but a comprehensive study by the Institutes of Medicine in 2004 looked for a relation between vaccines including the MMR and autism and they did not find a relationship. The other cause of concern has been the preservative by Thiomersal which is metabolized as Methyl Mercury and there was a sign of that perhaps, this was the cause of some of the neurological problems including autism, but again there have been no studies that have been found to support this link between Thiomersal and autism. To reassure parents a little more, however in 2003 Thiomersal stopped being put as a preservative in any vaccine except for the Flu shot and it is available as an alternative without Thiomersal.
