The furor surrounding vaccines and their relationship with autism has been rumbling along for decades.
A paper published in 1998 first described a link between the measles, mumps, and rubella (MMR) vaccine and autism.
Both the findings and the lead researchers have since been entirely discredited.
Anyone who takes an interest in science might be asking whether we need to carry out any more research in defense of the MMR jab. After all, strong evidence has already been collected, confirmed, and replicated.
