Police have arrested more than 130 suspects over a scandal in which 310 million yuan ($48 million) of illegal vaccines was sold onto the market. The value of the illegal trades could be as much as $90 million.
"This incident has highlighted the need for much stricter enforcement of vaccine management regulations across the board," WHO China representative Bernhard Schwartländer said in an emailed statement.
The vaccines, some targeting meningitis and rabies, are suspected of having been sold in dozens of places around China since 2011.
