The CDC has alarmed doctors and public health experts by changing language on its website related to vaccines and autism.

The Washington State Department of Health (DOH) is reaffirming that vaccines are a proven, essential tool for protecting people’s health.

The move is in response to changes on the U.S. Centers for Disease Control's website that promotes a possible link with autism.

Public health groups and physicians across the country have widely denounced new wording on the Center for Disease Control and Prevention’s website suggesting that vaccines could be linked to autism, despite decades of evidence showing they are safe.
