Now the Canadian pharmaceutical company Medicago is using tobacco plants to produce vaccines, including flu vaccines which can be made in quicker and in larger quantities. The process of creating the tobacco flu vaccine goes as follows: the DNA of the targeted viral protein is injected into a bacteria and left to multiply. Grown tobacco plants are then inverted and dipped into a dilute solution of the modified bacteria and then wrung like a sponge by a vacuum so the plants soak up the solution. After sitting in a chamber with controlled temperatures and lights, the plants are diced up and put in a digester which releases the protein by destroying the leaves' cellulose. Finally, the virus-like particles are collected and used for the vaccine. So far, the results seem to be hopeful and prove the tobacco flu vaccine would be able to keep up demands during an outbreak.
