Research and development of the hepatitis B vaccine
Abstract
Hepatitis b vaccine is a special drug for hepatitis b prevention. After the vaccination, may stimulate the immune system to produce protective antibodies that the antibodies present in the body fluids of the human body, HBV appears once, antibodies are immediately, to eliminate it, prevent infection, and will not harm the liver, so that the immunity of the human body with the prevention of hepatitis b, so as to achieve the goal of preventing hepatitis b infection. Hepatitis b vaccine is the most effective way to prevent hepatitis b virus infection. Current hepatitis b vaccine is a vaccine -recombinant hepatitis b vaccine and recombinant yeast-CHO hepatitis b vaccine, whose main ingredient is surface hepatitis b virus surface antigen of the hepatitis b virus, is a coat protein of hepatitis b virus, is not a full virus. Hepatitis b vaccine is produced by using genetic engineering techniques in genetic engineering, construction of recombinant plasmid containing HBSAG gene and transfect ion of host cells, such as yeast, CHO cells, and production of hepatitis b surface antigen proteins. Inoculation of hepatitis b vaccine is moving in an efficient, convenient and low-cost way.
