Among the new vaccines, China is basically the same as the international level in the research of new infectious diseases such as SARS, HIV and therapeutic hepatitis B vaccine; but it is in a relatively backward position in the research and development of cancer vaccines, subunit vaccines and combined vaccines. The incidence of AIDS caused by HIV infection in China has been increasing year by year, and has now entered a period of rapid growth. Phase II clinical research has been officially launched in Nanning, Guangxi in 2009. Phase II clinical research will be conducted by the Guangxi Zhuang Autonomous Region Center for Disease Control and Prevention, China Pharmaceutical and Biological Products Testing Institute, Jilin University National Engineering Laboratory for AIDS Vaccine and Changchun Baike Pharmaceutical Co., Ltd. jointly completed. China is a country with a large population. The annual economic loss caused by three diseases caused by HBV infection-chronic hepatitis B, cirrhosis, and hepatocellular carcinoma-amounts to 900 billion yuan, which has become a large economic burden on our people.
