A new study, the largest of its kind, has disproved the link between the measles, mumps and rubella (MMR) vaccine and autism. Anti-vaxxers have long since cited a previous study, later found to be fraudulent and subsequently retracted, as evidence of such a link.

Amid ongoing US measles outbreaks, one of the largest studies to date provides fresh evidence that the measles, mumps and rubella (MMR) vaccine does not cause autism.
“In a study of more than 650 000 Danish children, there was no difference in the risk of autism in vaccinated and unvaccinated children,” said lead researcher Anders Hviid. He is a senior investigator of epidemiology with the Statens Serum Institute in Copenhagen, Denmark.
But Hviid is sceptical the new findings will make much difference among anti-vaccine activists.
The discredited link between the MMR vaccine and autism dates back two decades to a study published in The Lancet that claimed a handful of children had been diagnosed with autism within four weeks of receiving the vaccination.
That study received wide publicity, but was subsequently retracted by the medical journal after discovery that the research was fraudulent.
Even with the overwhelming evidence that vaccines are safe and effective, some parents still decide not to have their children vaccinated or to delay vaccinations.
