CHICAGO — Illinois regulators have suspended the license of a suburban Chicago doctor who allegedly gives 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.

Dr. Ming Te Lin told investigators he’s been preparing alternative vaccinations for children at his office in Flossmoor for more than a decade.

He adds alcohol and sometimes cat saliva gathered with a swab from a cat’s mouth for patients with allergies. He told investigators he uses a device called the “WaveFront 2000” to detoxify vaccinations from mercury.

None of Lin’s methods are approved by the Food and Drug Administration.

The Illinois Department of Financial and Professional Regulation temporarily suspended Lin’s license. He has also been charged with administering unapproved oral versions of vaccinations.

The state tells WGN there are five known patients who received the unapproved vaccinations.

The youngest patient was reportedly just seven days old.

Lin admitted that in some cases he did not follow proper procedure, WGN reported. One of his patients who spoke with WGN off camera and defended Lin’s reputation, saying he is a wonderful doctor.

A disciplinary hearing is set for October 11.
