Potato Hepatitis B Vaccine Succeeds in Human Trial
Genetically Modified Potatoes Prevent Hepatitis B (Sansi Science Report) American scientists have developed a genetically modified potato that may act as a hepatitis B vaccine, which is good news for developing countries. The hepatitis B virus attacks the liver and claims about 500,000 lives each year. But traditional vaccines require refrigeration, which is difficult to achieve in remote areas of warm developing countries.
