Who would have thought that the study of the deadly Ebola would result in a new and beneficial way of delivering gene therapy? Until now, the viral delivery packets containing the therapeutic genes had to be injected since digestion destroys them. But how do you can't inject into the lungs. Now they have created a viral shell similar to Ebola that is even better at penetrating cell walls. Fill that shell with good genes and it can be inhaled and be effective.
