Behind every advance in vaccine research, there is a man or
woman--often a group--whose contributions to the field are
worthy of historical note. Without Edward Jenner, smallpox could
not have been defeated. Without Jonas Salk and Albert Sabin,
polio might still be spreading, unchallenged, throughout the
world.  The discoveries that seem smaller, or were not publicly

in Montana. The descendants of the flock of specially bred

and the fight against diseas
