Actually, when I posted that story from Tampa, I was wanting to point out the folly of having thousands of older folks lined up shoulder to shoulder outside vaccination centers. If they had not already been exposed, the situation in those photos looks like it would make sure of it.
As to priorities for older adults, I would say that I agree that those living in nursing homes/assisted living definitely should get priority, and probably also anyone with a chronic condition that often sends them to a doctor's office, but I'm not so sure about healthy retirees who still live independently. Society at large has a vested interest in getting the working-age healthy back to work if they have lost jobs due to the pandemic, and in protecting those who have higher-risk health conditions but must work in person in situations where they come into close contact with large numbers of people. (And yes, some teachers may fall into that category. That is not usually going to be the 22yo teacher; it would more often be the 55 yo teacher who is diabetic.)
I think that where it really gets complicated for Florida is service workers in the hospitality industries. You want to get them back to work so that they are not falling into dependent poverty, but OTOH, if you send them back to work to a business that has no customers because the customers cannot yet access the vaccine, what has been accomplished?
