All medications and vaccines have potential risks that must be carefully weighed against the benefits that medications and vaccines offer to prevent illness. Today, vaccines are considered safe. Braz J Med Biol Res. The disadvantage of the recombinant subunit vaccine is that it is difficult to design a good structure of a recombinant protein and the expression system. pain in the abdomen. 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). To make recombinant plasmids, two different plasmids are cut with the same, The goals of this lab report are to induce E.coli bacteria for producing protein of interest and determined the rate growth and protein concentration after inoculate the E.coli culture. DNA vaccines include DNA that creates specific antigens from a germ. Subunit vaccines isolate specific antigens from a germ or virus for use in the vaccine, and these antigens are specifically chosen according to the strength of the immune response they generate.
