The issue is what happens once the vaccines leave the factory. The government-distributed, free (EPI) vaccines are distributed through a tightly managed, cold chain system.
A WHO-UNICEF evaluation of the EPI management system in 2014 and 2015 concluded that capacity to effectively manage vaccines is very strong.
The problem that last week's events have brought to light, is that distribution of vaccines for the private market do not follow the same high standards.
And sadly, this weakness in the system has been exploited by an unscrupulous few intent on making some quick cash, without any apparent regard for the implications for children's health.
China's EPI system is one of the best in the world.
The results speak for themselves: over 99% of Chinese children are now free for life from chronic hepatitis B as a result of use of hepatitis B vaccination. Poliomyelitis was eliminated 16 years ago. The incidence of measles is 99% lower than during the pre-vaccine era.
These accomplishments should inspire confidence.
The ongoing investigation by health authorities and the police into China's vaccine reselling ring shows how seriously the Chinese government is taking this incident.
WHO is in close contact with the health authorities as they conduct their investigation, and have offered our full support.
I’ve lived in China for quite a considerable time including my graduate school years, travelled and worked in a few cities and still choose my destination taking into consideration the density of smog or PM2.5 particulate matter in the region.
