Measles is especially pernicious, too. Not only is having measles deeply unpleasant at best and fatal at worst, surviving it leaves you more susceptible to other knock-on diseases for something like two or three years. Widespread measles vaccinations cratered the measles death rate, obviously, but it also cratered the deaths from pneumonia and the like. Per [0][1][2], the epidemiological data is suggestive of this -- but sequencing the virus and poking around at its RNA is starting to figure out exactly how sneaky of a thing the virus is.
