A decade long study into the effects of immunizations on children has found no links to autism a Danish–led group has discovered!

A study, led by Danish scientists, which has been underway for over a decade and includes over 650,000 children has finally put the immunization theories and misinformation to rest. They have concluded that there is no link between the mumps, rubella and measles vaccines. Lately, social media and mainstream media have been full of stories regarding parents who have ongoing concerns about vaccinations and their alleged links to autism and other developmental conditions.

The study conducted in Denmark is one of the largest research projects ever undertaken into vaccines and their links to developmental conditions. This is in the face of measles outbreaks around the world which many health experts believe are the result of the anti-vaxxer movement.

“The study strongly supports that MMR vaccination does not increase the risk for autism, does not trigger autism in susceptible children, and is not associated with clustering of autism cases after vaccination,” the authors wrote in the study published this week in the Annals of Internal Medicine.

The study sampled over 650,000 children that were born in Denmark between 1999 and 2010. They used Danish population registers to check information on autism diagnoses, vaccinations and other risk factors such as whether a child had a sibling diagnosed with autism spectrum disorder(ASD).

Among the children involved in the study, 6,517 were diagnosed with autism. Children that had been vaccinated didn’t develop autism at a higher rate than those that weren’t vaccinated. Nor were they placed at higher risk of developing autism. “Vaccine hesitancy is increasing,” study author Dr. Anders Hviid said in an email. “Today, we are seeing the results in the form of more and more measles outbreaks in Europe and the U.S.”

Many governments around the world are currently looking at changing vaccination exemption laws to fight the ongoing measles outbreaks. Social media platforms such as Pinterest, Facebook and YouTube have even begun to remove anti-vaxxer content unless it is backed up with scientific data and accreditation.
