The World Health Organisation has urged China to strengthen its oversight of private immunisations after a scandal involving the illegal trade of expired and improperly-stored vaccines.
Dr Lance Rodewald of WHO China's Expanded Programme said the investigation into the "troubling" illegal vaccine trade would help identify ways the regulation of China's private vaccine market can be improved.
"The vaccines that are in the private sector need to be managed, stored, handled, distributed and used in accordance with recognised standards," said Rodewald at a press conference in Beijing on Tuesday.
Sixty million dollars worth of illegal vaccines were discovered in China’s northeast province of Shandong.
Chinese police say a woman and her daughter are thought to have sold the illegal products nationwide since 2011. Both have been detained.
