A friend's favorite Wiki page is on the micromort. [1] I found it kind of banal, but perhaps that's my more casual attitude towards death. I suspect the average person doesn't realize, or doesn't accept, how brief life truly is. One micromort is something with a 1 in a million chance of death. So with measels, we're talking about 1000 micromorts, if you're infected - which is also extremely unlikely. So if you give yourself a 1% chance of ever being infected with measels (which would be quite high) then not vaccinating would be down to a 1% * 1000 = 10 micromorts of risk.
All non-natural cause of death in the US, excluding suicide, is about 1.3 micromorts per day. So it's the same all non-natural cause risk you'll be exposed to over the next week. The page offers a lot of other comparables - traveling 100 miles by biking, 2500 by car, or 10k by airplane, and so on.
