You shouldn't speculate without doing a bit of homework first. The Ebola virus is reported to have a mutation rate that is approximately 100 times slower than the influenza virus, making it more like other human viruses, which also tend to mutate slowly. (HIV is an extreme outlier with its extraordinary mutation rate.) The RNAi sequences used in this experiment will likely work for quite a few years.

The investigators plan to do safety tests in humans next, but they have some preliminary data on safety this is positive.
