BEIJING, March 31, 2005 – Sinovac Biotech Ltd. ("Sinovac") (“the Company”) (AMEX: SVA) announces that it has commenced the marketing launch of Bilive™, its combined Hepatitis A & B vaccine. Sinovac held its official marketing launch for the sale of Bilive™ during the period of March 25-27 in Huang Mountain, Anhui Province, China. Top medical professionals and hepatitis
specialists from across China, and about 130 doctors from China’s Center of Disease Control attended the launch. The feedback from the attendees was very positive. During the meeting, it was further agreed that the Chinese vaccine industry will promote the use of inactivated vaccines such as Sinovac’s Bilive™ in the prevention of infectious diseases such as viral hepatitis.
China is a country that has been greatly affected by viral hepatitis for a long time. The prevention and control of hepatitis is very important for the country’s social development and public health. Sinovac expects to record the first sales of Bilive™ by May 2005.
BiliveTM is a state-of-the-art combined hepatitis A and B vaccine. It can be recommended to protect people against Hepatitis A and Hepatitis B. BiliveTM will be sold in two forms based on the age of vaccinees. BiliveTM junior is for use in non-immune children and adolescents from ages 1 to 15 years, and BiliveTM adult is for use in non-immune adults and adolescents 16 years of age
Bilive™ is a combined vaccine formulated by purified inactivated Hepatitis A virus antigen and recombinant (yeast) hepatitis B surface (HBsAg), absorbed into aluminum hydroxide. The vaccine induces the body’s immune system to generate antibodies as a reaction against hepatitis A and hepatitis B viruses. Hepatitis is one of the major diseases of mankind and continues to be a serious global public health issue. It is preventable with safe effective vaccines.
About Hepatitis B
Hepatitis B is a very common infection. Each year in the United States, an estimated 200,000 persons are newly infected with hepatitis B virus. More than 11,000 of these people are hospitalized, and 20,000 remain chronically infected. Overall, an estimated 1.25 million people in the United States have chronic hepatitis B virus infection, and 4,000 to 5,000 people die each
year from liver disease or liver cancer related to hepatitis B. Nearly 300 million persons in the world are chronically infected with hepatitis B virus. High rates of chronic infection are found in some parts of China, Southeast Asia, Africa, the Pacific islands, the Amazon Basin in South America, and the Middle East.
Of the 2 billion people who have been infected with the hepatitis B virus (HBV), more than 350 million have chronic (lifelong) infections. These chronically infected people are at high risk of death from cirrhosis of the liver and liver cancer, diseases that kill about one million people each year.
