Anthrax sent by Pentagon to U.S. Air Force base in South Korea, 22 people may be exposed

After the Pentagon admitted an Army laboratory accidentally distributed live samples of anthrax, a U.S. Air Force base in South Korea now says 22 of its personnel "may have been exposed."

"Twenty-two personnel may have been exposed during the training event and all personnel were provided appropriate medical precautionary measures to include examinations, antibiotics and in some instances, vaccinations," a statement from Osan Air Base said. "None of the personnel have shown any signs of possible exposure."
