Atkinson, W. Feigin, R. Textbook of Pediatric Infectious Diseases , 5 th ed. Philadelphia: Saunders, Immunization Action Coalition. Unusual cases of hepatitis B virus transmission. Plotkin, S. Vaccines , 5 th ed. World Health Organization. American physician and researcher Baruch Blumberg, MD, PhD , was interested in how genes could influence susceptibility to disease. He traveled the world collecting and studying blood samples from different populations.

With a new lab technique, he matched a protein found in the blood of an Australian aborigine with an antibody in the blood of a hemophiliac from the United States. He called the protein the "Australia antigen. Blumberg and others were able to connect the presence of the antigen with hepatitis B infection. Later they related HBV infection to liver cancer.

The Australia antigen circulates in the blood of a previously infected person not only as part of HBV, but also as a small, independent particle. The discovery of the Australia antigen had an important effect on the study of hepatitis B, in large part because HBV cannot be cultivated in the lab.

The Australia antigen could, therefore, serve as a model for the virus as a whole. Moreover, the Australia antigen provided a source for antigen for the vaccine. This hepatitis B vaccine was the first human vaccine produced by recombinant DNA methods. Researchers inserted the code for the antigen into yeast cells, which produced more of the surface protein. The yeast-derived surface protein produced immunity to the hepatitis B virus. Article Menu [ ]. Vaccine Science [ ]. Biological Weapons, Bioterrorism, and Vaccines.
