Although it was a decade ago since the Lancet published an article that had been published in the same journal by physician Andrew Wakefield – in which he claimed that the relationship between autism and measles, mumps and The Rubeola was very tight – people still have doubts about people all over the world. For this reason, the scientists have continued their research to show that such a link does not exist and to fight the strong group of vaccines.
The latest study published this week in the Annals of Internal Medicine follows a study by scientists from the Staten Serum Institute in Copenhagen, adding data on Danish children born between 1999 and the end of 2010, in a total of 650 Thousands of people examined in which 6,517 were diagnosed with autism.
In this way, epidemiologists and statisticians used the population registers to associate the vaccination status with the diagnoses of the disorder. According to reports from around the world, the results have shown that vaccines do not increase the risk of autism.
In particular, it was found that children vaccinated against measles, mumps and rubella did not develop significantly different autism from those who did not receive the vaccine.
In addition, the researchers analyzed the children most at risk for the disease, including families in families with other children with autism or children who had risk factors to present them.
And the results showed that there was no greater tendency among these minors. Finally, the researchers reviewed the time when the autism was diagnosed and found that no further cases occurred after vaccination of the children.
Anders Hviid, lead author of the study, said they had decided to conduct the new research because they saw skepticism about vaccines continue to increase. "We thought it would be a good idea to test the hypothesis and try to get scientific answers to the various criticisms," he said after Time.
Given the overwhelming results, Hviid is confident that parents can finally be convinced that the measles, mumps and rubella vaccine are safe.
"There is a large group of parents who are affected and they welcome the idea that vaccines cause autism or cancer (…). We hope that the data can reduce some of these concerns and convince people that the vaccine does not cause autism, "he said.
Hviid recalled NBC News's dangers of non-vaccination, including "a resurgence of the measles that we see today in the form of outbreaks". It should be recalled that last November WHO warned of a continued increase in measles cases worldwide, and even one of its officials said it had lost ground "because people forget that it is a terrible disease".
Measles are highly contagious and can be fatal or lead to hearing impairment and mental disorders in children.
