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. Cancer Vaccines and Immunotherapy.

Babies at high risk of developing hepatitis B infection from infected mothers are given additional doses of the hepatitis B vaccine at birth, 4 weeks and 1 year of age.
If you think you're at risk and need the hepatitis B vaccine, ask your GP to vaccinate you, or visit any sexual health or genitourinary medicine GUM clinic. If your GP or nurse is unable to offer you the hepatitis B vaccine because of a temporary shortage in supply, you may need to wait longer for the vaccine.
For more information, read What to do if you have to wait for a dose of hepatitis B vaccine PDF, kb. If your job places you at risk of hepatitis B infection, it's your employer's responsibility to arrange vaccination for you, rather than your GP.
Contact your occupational health department. Full protection involves having 3 injections of the hepatitis B vaccine at the recommended intervals. Babies born to mothers with hepatitis B infection will be given 6 doses of hepatitis B-containing vaccine to ensure long-lasting protection. If you're a healthcare worker or you have kidney failure, you'll have a follow-up appointment to see if you've responded to the vaccine. If you've been vaccinated by your employer's occupational health service you can request a blood test to see if you've responded to the vaccine.
If you've been exposed to the hepatitis B virus and have not been vaccinated before, you should get immediate medical advice, as you may benefit from having the hepatitis B vaccine. In some situations, you may also need to have an injection of antibodies, called specific hepatitis B immunoglobulin HBIG , along with the hepatitis B vaccine. HBIG should ideally be given within 48 hours, but you can still have it up to a week after exposure.
Pregnant women have a routine blood test for hepatitis B as part of their antenatal care. Babies born to mothers infected with hepatitis B need to be given a dose of the hepatitis B vaccine within 24 hours of their birth, followed by further doses at 4, 8, 12 and 16 weeks of age, plus a final dose when they're 1 year old. Babies of mothers identified by the blood test as particularly infectious might also be given an injection of HBIG at birth on top of the hepatitis B vaccination to give them rapid protection against infection.
All babies born to mothers infected with hepatitis B should be tested at 1 year of age to check if they've become infected with the virus. Hepatitis B infection in pregnant women may result in severe disease for the mother and chronic infection for the baby.
This is why the hepatitis B vaccine is recommended for pregnant women who are in a high-risk category. Abrir menu.
