The head supervision at China’s Food and Drug Administration Li Guoqing told reporters at a press conference on Thursday that the woman at the center of an illegal vaccine scandal had previously been given a suspended jail sentence for a similar crime but was allowed to re-offend, Reuters reported. US$90 million worth of expired or improperly stored vaccines for rabies, meningitis and other illnesses are suspected of being sold throughout China since 2011. “At present our country has 12,000 drug wholesalers, 5,000 production firms and more than 400,000 drug retailers. Regulatory targets are many, but there are few people on the ground, making regulation difficult,” Li said.
