Banana Vaccine

Dr. Charles Arntzen of Arizona State University developed a banana that is genetically engineered to provide a hepatitis vaccine. (Hepatitis is a virus that causes liver disease in humans.) Dr. Arntzen also uses potatoes as a way to carry a vaccine against a strain of E. coli that causes bleeding and fluid loss in the intestines. Potatoes have also been genetically engineered by a researcher in California who created an edible cholera vaccine by adding the genes for the cholera toxin to the potato' s genetic code. (Cholera causes a diarrhea that can lead to severe dehydration and possibly death.)
