Well the data is pretty clear on who the vulnerable are in this situation. I think it calls for being a bit myopic. Folks that are 80+ are the ones at high risk of dying. USA has 3 million folks 80+. Have all of them shelter in place, self quarantine, or social distance. Use 1% of the soon to be trillion dollar stimulus bill and have all of their groceries, medicine, etc... delivered by someone in a hazmat uniform for the next few months. Let everyone else go about life with a slightly worse than normal flu season, while at the same time building up herd immunity.
