Concerns about a potential link between the MMR vaccine and autism have persisted for two decades, since a controversial and ultimately retracted 1998 paper claimed there was a direct connection.
The study which was published in Annals of Internal Medicine journal on Monday came to a conclusion that MMR vaccine did not cause or increase the risk of autism in children who did not have the risk for the disorder and also that it didn't trigger the disorder in those who were at a risk. In all, they had access to data from 657,461 children; of these, 6,517 received an autism diagnosis during the 10-year follow-up.

Measles is a highly contagious virus that can be fatal.
The illness typically begins with cold-like symptoms, including a high fever, cough and runny nose. A rash develops on the face and neck and then spreads to the rest of the body. It might also lead to serious complications such as pneumonia and encephalitis (swelling of the brain). After an infected person leaves a location, the virus can live for up to 2 hours in the air or on surfaces where the infected person coughed or sneezed. "Immunization helps protect you, your family, and your community from this risky and largely preventable virus".

Overall, 95% of the kids in the study got the vaccine. The authors note it was also very possible that the onset of autistic symptoms may lead parents to not vaccinate their child.The fact of the matter is that children with siblings who have autism are seven times more likely to be diagnosed with autism themselves.
Boys were four times more likely to be diagnosed with autism than girls, the study found. So while "children who had no childhood vaccinations were 17 percent more likely to be diagnosed with autism than kids who did get recommended vaccinations", may seem like smoke-it isn't exactly fire either. Behavioural, educational, speech and language therapy may help reduce the severity of autism symptoms in some children.
Subsequent studied that attempted to reproduce the results did not find any link between the vaccine and autism. "MMR is a highly effective and safe vaccine". Now, the researchers do not say there is a causation between getting the vaccine and not having autism. A large study has proven conclusively that there is no association between Measles Mumps and Rubella combined vaccine or the MMR vaccine and autism.More news: Carleton professor among the dead in Ethiopian Airlines crash
"Any myth should be clearly labelled as such", Omer writes.
The findings show that the vaccine does not increase the risk of autism, lending new statistical certainty to what was already medical consensus.More news: Xiaomi Black Shark 2 will Launch on March 18
