How serious is the North Korean anthrax threat?

Presidential spokesman Park Soo-hyun said the Korea Centers for Disease Control and Prevention bought 1,000 doses of anthrax vaccines, to be given to biochemical counterterrorism agents or civilians in the case of anthrax exposure. The vaccines arrived in November.

Park said the Blue House had bought 350 doses of anthrax vaccine to counter accidental exposure, but he said it was ordered by the previous government led by former President Park Geun-hye after an incident in 2015.

Then, it emerged the US military erroneously shipped live anthrax used for research purposes to South Korea, as well as parts of the US, Canada and Australia. The sample sent to South Korea was destroyed and the facility decontaminated.
