Autism and vaccines - no scientific link

There has been a recent addition in the series of studies showing no association between vaccines and autism: a study conducted in non-human primates. Gadad and colleagues investigated the MMR vaccine (measles, mumps, rubella vaccine), thimerosol containing vaccines, as well as past and current pediatric vaccine schedules and found no association with autism-like behaviors and neuropathology.

autism vaccine researchOffit wrote an interesting commentary on the study. He highlighted the fact that since the different hypotheses regarding a potential link between vaccines and autism had been put forward, they had all previously been investigated in human epidemiological studies and no association with autism was reported. Offit also discusses the fact that despite the retraction of the Wakefield study that had claimed a link between autism and the MMR vaccine, the impact that publication had could not be retracted and that until we know the cause(s) of autism there will be doubt about vaccines.
