@mark noble,
I see youre a fan of conspiracy newslines. Bubonic plague, rabies, Polio and several other viral infections remain also. You seem to have no understanding nor respect for medical research. Waht year school did you complete??
Ive been reading that with gene editing certain virus can be mutated out of their virulent status. Im not sure thats a good ide because if we engineer the virus and it makes a small mutation in a host with its own bit of luck, it could have a swell time re infecting the un protected portion of the population.
