The World Health Organization said that it’s confident in China’s vaccine distribution and manufacturing. But, the public remained skeptical following recent scandals.

CCTV’s Wu Guoxiu reports from Beijing.

Amid widespread public concern and questions from the media, the WHO expressed its confidence in Chinese vaccines.

The WHO spoke to the media in Beijing, following a recent report of vaccines being purchased by a private family and resold to hospitals and clinics throughout the country.

In the recent scandal, a large quantity of improperly stored or expired vaccines were reportedly sold across China since 2011. The WHO said the incident has revealed problems in the supply chain – the distribution of vaccines available for purchase on the private market.

China’s State Council has set up a cross-department team to investigate the case and a supervision team to oversee the investigation.

Premier Li Keqiang said regulatory bodies, including the China Food and Drug Administration (CFDA), health ministry and police, need to work together and that dereliction of duty would not be tolerated.

Investigators are still tracing the distribution of the vaccines.

A total of 69 criminal cases have been filed and 130 people have been apprehended. Investigators said the vaccines were not produced and sold by illegal factories. Instead, they are normal vaccines sold by legal factories.

Responding to parents’ concerns, the WHO said the illegally traded vaccines will not lead to side effects or toxic reactions, but some children may need to be re-vaccinated.
