No one can forget the disease SARS. It was first found in Guangdong province in late 2002.
The disease began to spread to the other part of China in the spring of 2003.
It killed hundreds of people and affected more than 8.000.
Chinese scientists have begun testing a SARS vaccine on Beiging volunteers.
Those volunteers are very young but their bravery is highly appreciated.
I hope the new medicine will soon appear.
