I've redrawn this concept here. We have viral abundance on the x-axis in arbitrary units of 0% to 100% and population immune pressure on the y-axis also in arbitrary units. Viral adaptation is plotted by color and is just abundance × immune pressure. 4/19 pic.twitter.com/TAZgbEmGHG

Grenfell et al. 2004 (https://t.co/1uq4qZvP2f) lays out the conceptual foundations for thinking about this problem. This figure is a bit hard to parse, but basically vaccination will increase population immunity and move rightward on the x-axis. 2/19 pic.twitter.com/L7odPQAPEH

and then here's suicides, homicides, and accidental poisonings for Massachusetts in the long run. I like MA because 1) clear increase in organized crime in the relevant period, 2) not confounded by changing coverage areas like the all-US data. pic.twitter.com/gkUGyZXro6
