CHICAGO -- Illinois regulators have suspended the license of a suburban Chicago doctor who allegedly gives young patients modified vaccinations containing cat saliva and vodka.

The Illinois Department of Financial and Professional Regulation on Wednesday ordered the emergency action in the interest of public safety.

The order says Dr. Ming Te Lin told investigators he's been preparing alternative vaccinations for children at his office in Flossmoor, adding alcohol and sometimes cat saliva gathered with a swab from a cat's mouth for allergies. He also told investigators he uses a device called the "WaveFront 2000" to detoxify vaccinations from mercury.

None of Lin's methods is approved by the Food and Drug Administration.

A phone message left for Lin and email seeking his comments on the allegations were not immediately returned.
