An interesting approach. They use a live version of the target virus (any virus they claim) and weaken it so it can't suppress our RNAi response, making the virus lose a battle it may otherwise have won, teaching our immune system in the process. Could be very effective, the next thing I'd want to see with this method is if that live virus still manages to reach immune privileged areas (central nervous system, brain, eyes, etc) and set up for chronic infection where our response can't access.
