SEOUL, Nov. 8 (UPI) -- South Korea said it will recall Bacillus Calmette-Guerin (BCG) vaccines manufactured in Japan as arsenic, a toxic substance, was detected.
The Japanese Ministry of Health, Labor and Welfare stopped distribution of new BCG vaccine products in August after it found a low dose of arsenic in the vaccine's physiological saline. According to the ministry, a vaccine could contain up to 0.26 parts per million (ppm) of arsenic, 1/38 of the maximum amount allowed per day.
