  I think John Brunner had a book where time travelers
came to our time from the future and deliberately spread a
plague that had affected 1/3 of the population with 10
percent mortality.  In their time nearly everyone was
vulnerable and the mortality rate was 90 percent.
   They were hoping to breed some immunity into the human
race and make sure medicine remained an active science.

   There is a belief that the survivors of the Black
Plague had some genetic resistence which now gives their
descendents a little immunity to HIV/AIDS
