The effects of the vaccine in animals have been “promising,” Canadian authorities said. The vaccine is just beginning to be tested on human subjects in order to determine the safety of the vaccine and the dosage required to stimulate a person’s immune system into producing the proper antibodies. Canada is sending [800 vials](http://news.gc.ca/web/article-en.do?mthd=index&crtr.page=1&nid=894989 "undefined") of experimental Ebola vaccine contained at -80 degrees celsius in three separate shipments via aircraft to the WHO in Geneva. Canada’s Public Health Agency is supplying it to the WHO so it can be used as an “international resource.” “This vaccine, the product of many years of scientific research and innovation, could be an important tool in curbing the outbreak,” said Dr. Gregory Taylor, Chief Public Health Officer of Canada. ### See The Tobacco Leaves That Could Cure Ebola  Tobacco plants are grown for six weeks in the Medicago greenhouse in Quebec City so their leaves are large enough to serve as a factory for making antibodies. The plants are not modified or genetically altered in any way during this time. Mathieu Belanger—Reuters  Researchers at Icon Genetics in Germany prepare the DNA coding for antibodies that can neutralize Ebola. These genes are inserted into a soil bacterium that easily infects the tobacco plant cells. Once in the cells, the gene is treated like any other plant gene and the plant starts churning out the antibodies. Sean Gallup—Getty Images  To infect the leaves with the antibody-containing bacteria, the plants are submerged in a water solution of the loaded bacteria. Plant cells have plenty of empty spaces filled with air, so a vacuum removes the air and the water, along with the bacteria and antibody genes, flow in. Mathieu Belanger—Reuters  The leaf at the bottom has not been treated. The leaf on top is now an antibody-making factory. The plant's normal machinery starts making the antibody as if it is a plant protein. Mathieu Belanger—Reuters  Researchers at Icon Genetics grind the leaves down to filter out the antibodies. Sean Gallup—Getty Images  Ultraviolet light reveals the clusters of cells that are busy making antibodies. One kg of leaves produces about 5g of antibodies, which is about a third of the dose required to treat an Ebola patient.
