The residents who didn't get it: those working 80+ hrs/week in the emergency room, in the ICU, intubating patients, operating on patients, etc etc etc

Some people I know of who got it instead: Radiologists who primarily work from home. Administrative roles with relatively low (or no) patient interaction.

Not saying those people shouldn't get vaccinated -- just that if you were asked to come up with a priority list, it wouldn't be this.
