Doctors at Danbury Hospital are hopeful that a new study will encourage parents to have their children vaccinated.

Some parents have chosen to bypass their children's vaccines due to the fear that they may cause autism.

The return of measles has some medical professionals blaming the "anti-vaxxer movement."

A 10-year study from Denmark called "Annals of Internal Medicine," looked at more than 650,000 children and discovered no link between the MMR vaccine and autism.

The investigation took multiple factors into consideration, including other childhood vaccines and sibling history of autism.

"They actually included children with autism, as well as kids who are at risk for autism in the study," said Dr. Beth Natt of Danbury Hospital. "And what they showed was there's no evidence that it causes autism, no evidence that there's an association between when the vaccine is given and when autism happens."

Natt says children should receive two doses of the measles vaccine--once at 12-15 months and again at 4-6 years old.

She also tells parents to watch out for symptoms of the disease, which could include a fever, dry cough, runny nose or a rash that starts on the face and spreads to the rest of the body.
