It affects the liver by causing a wide range of diseases, from acute hepatitis (including fulminant hepatic failure), to chronic hepatitis, cirrhosis and potentially hepatocellular carcinoma (Liang, 2009). Moreover, they can be easily produced at a large scale. The use of attenuated vaccines is too risky for pathogens such as HIV, and a safer alternative is to develop a live, recombinant vector vaccine where one or a few pathogen genes with immunogenic activity (proteins that elicit protective immunity) are expressed from a benign virus vector. Other advantages include being well-established technology and being suitable for immunocompromised individuals. This results in creating new traits that were not previously present in the organisms genome.
