Professor Sung Juei-Low is the predecessor of hepatitis B prevention in the country. After the “Australian Antigen” was discovered and the mystery of hepatitis B was unveiled, he discovered that as many as 3 million people in Taiwan are carriers of hepatitis B, and he worked with students Liao Yun-Fan, Chen Ding-Shinn, and others to prove that hepatitis B virus is the main culprit of liver cirrhosis and liver cancer. He also defined the body fluid transmission route of hepatitis B, confirming that Taiwanese hepatitis B patients are mostly infected through vertical transmission. Under the joint efforts of Sung Juei-Lo, Luo Kuang-Rui, Chen Ding-Shinn and others, in 1986, Taiwan fully injected all newborns with the hepatitis B vaccine to block vertical transmission, making Taiwan a pioneer in global hepatitis research and epidemic prevention. Professor Sung Juei-Low’s achievements in gastroenterology and liver medicine research and teaching have made a significant contribution to the improvement of Taiwan’s research standards. He was awarded the first (2001) Presidential Science Award – Life Science Group.
