turing are no longer usable. The result is the sudden onslaught of an epidemic. The Black Death was undoubtedly brought about by a mutant strain of the microorganism causing it. Eventually, though, those human beings who are most susceptible die, and the relatively resistant survive, so that the vir- ulence of the diseases dies down. In that case, is the human victory over the pathogenic microorganism permanent? Might not new strains of germs arise? They might and they do. Every few years a new strain of flu rises to pester us. It is possible, however, to pro- duce vaccines against such a new strain once it makes an appear- ance. Thus, when a single case of “swine flu” appeared in 1976, a full scale mass-vaccination was set in action. It turned out not to be needed, but it showed what could be done.
