According to a study published in the Annals of Internal Medicine, the latest evidence denies any link between autism and the vaccine for measles, mumps, and rubella. A two-dose course that the Centers for Disease Control and Prevention says is 97 percent effective in combatting those diseases.

Researchers at Copenhagen’s Statens Serum Institut used data for Danish children born from 1999 through the end of 2010, more than half a million people.

Why then are people afraid to get their children vaccinated?

Andrew Wakefield a doctor made a Claim that vaccines might be the cause of autism. That claim was refuted nine years ago by a British medical panel and concluded in 2010 that Andrew Wakefield, had undisclosed financial interests in making such claims, and had acted with “callous disregard” in conducting his research.

Professionals are devoting time and resources to discrediting Wakefield’s work. Many parents after reading his theory stopped getting their children vaccinated. Measles was almost eliminated in the U.S in 2000.
