One other thing to note in this graph. Sometimes, anti-vaccine folks will simply draw a straight line following the general slope of the data and extrapolate that by 2010, measles would not cause any deaths and would be gone on its own. But that ignores changes in medical care that occurred over that span of time, as well as ignoring changes in the slope itself. We see, for instance, that there's a gradual decline until the early 1920s, then a slightly steeper slope until the late 1940s, with a leveling off in the 1950s. A perfectly straight line just doesn't fit, at least if one is being honest. We see a precipitous drop in the number of cases around 1963. Notice, also that while death rates had been declining, those also dropped about ten-fold in the space of a few years. Compare that to the pre-vaccine era, where it took decades for an equally great drop in death rates (e.g., 1918-1943 and 1943-1967). That impact is something that you don't see in the graph favored by anti-vaccine folks.
