Tobacco plants engineered to produce polio virus protein coat – an effective vaccine?

This might be a major breakthrough in the fight against viral diseases. An inactive virus often generates the same immune response as an active virus. In this case, just the protein coat of the polio virus tricks the body into believing there is need for an immune response. Fine! But how then to produce quantities of this mimic virus to use as a vaccine? Engineer the specific piece of the viral gene into tobacco plants and within three weeks they are producing the viral protein coat. Extract this and make the vaccine. Relatively cheap, easy and quick, with the potential to be a faster way to combat viral outbreaks such as the recent Ebola epidemic.
