Those theories have been blamed for a drop off in vaccination rates in some places around the world, exposing kids to childhood diseases that are known to kill and cause permanent disabilities.
"The dangers of not vaccinating includes a resurgence in measles which we are seeing signs of today in the form of outbreaks", Hviid said by email. One teen who defied his anti-vax parents to get inoculated became a folk hero of sorts last week.
"Autism is equally prevalent amongst the children who had received the MMR vaccine and the total of 31,619 children who were not vaccinated".
The study wasn't a controlled experiment created to prove whether or how vaccines might cause autism.
The percentage of vaccinated children in Denmark was under 90 percent during the 2000s, but has increased to just over 90 percent since 2012.
The researchers also found no increased risk among subgroups of children who might be unusually susceptible to autism, such as those with a brother or sister with the disorder.
Gary Freed, professor of health management and policy at the University of MI, expressed similar thoughts. The change showed no drop in the number of autism diagnosis.
A study of more than half a million children in Denmark shows there is no link between autism and the MMR vaccine, which is used to protect against measles, mumps, and rubella. The children were followed-up again at ages one and 14.
"Parents should not skip the vaccine out of fear for autism", the study's lead author told media.
Boys were four times more likely to be diagnosed with autism than girls, the study found. Not a single study afterward ever corroborated Wakefield's hypothesis at all, and by the time Lancet finally withdrew the study's publication twelve years later, the British medical community had concluded that Wakefield was a fraud.
The findings come amid heightened concerns about people forgoing vaccination with the World Health Organization recently naming vaccine hesitancy to its list of top 10 threats to global health in 2019. The new Danish study might counteract the conspiracy thinking, but, er ... don't hold your breath. In severe cases, pneumonia and encephalitis, an inflammation of the brain, can develop.
"Anti-vaxxers" refuse to immunise children, in the (mistaken) belief that vaccines cause conditions such as autism. Some children won't be, and it's all on Wakefield's head. The second is the testimony of the young man who broke away from his parents' control to escape the anti-vaxx movement, followed by an ABC News profile of Lindenberger and his family.
