"I met Dr Weidong Yin for the first time in 1996 when I went to Tangshan, China. At that time, he was involved in research. He was very young then and was running a very small scale company. But, he was determined to find a remedy against hepatitis A virus. He is a very charming man and he has always believed that one should always stick to something and never give it up."

Mr Yuk Lam Lo, independent director, Sinovac

"Supplying vaccines to eliminate human diseases is the mission of Sinovac. This mission has encouraged everybody at Sinovac to devote themselves to achieve this mission. Dr Yin is an able leader who steers the company towards growth with the changing business environment."
