The outcome doesn't bother me. The reasoning for high social value professions vs. low social value does, since it works for non-contagious situations as well.

The teachers continue to be the ones "taking care of our beloved children, the next generation"; The nurses continue to be "healthcare heroes"; the firefighters continue to be "brave and courageous"; all this continues to be true when I'm getting in line to have pancreatic cancer treated. I don't want to die because some pretty primary school teacher showed up at the last moment for that kidney transplant and society has decided that it wants her more than it wants me.

And obviously I have no objection to vaccinating high-degree nodes before low-degree nodes subject to the usual arguments.
