DNA vaccine production. Workers packing bottles containing recombinant hepatitis B vaccine. Traditional hepatitis vaccine contains the full virus,which could potentially become active and infect patients. A recombinant vaccine is made by inserting a piece of DNA from the virus into another organism,such as a bacterium. The viral protein is expressed by the genetically modified (GM) bacterium and purified for use as a vaccine. Because the vaccine only contains a viral protein,and not the whole virus,there is no risk of the virus becoming active.
