Deadly virus fuels bio-terror fears. “Scientists who accidently (sic)
created a deadly
version of mouse smallpox in the laboratory say
lethal human viruses are only a step away.

The prospect of such dangerous organisms
being produced relatively easily have left
bioterrorism experts fearful of killer global
epidemics.” Subtle modifications to the genome of a virus can, it seems, render it much more virulent and render vaccines useless in producing immunity. Scientists are already busy making small modifications to various pathogenic viruses to use them as vectors to carry genes into the body’s cells for genetic therapy. BBC
