I got mine a little bit ago. The hospital I'm at was offering them. First, they were offering them to 1A workers, which were considered those people who are at highest risk, or deal with the sickest people, so that was ED staff, ICU (all forms: MICU, PICU, SICU, CCU, etc.), recovery room. Then, it was made available to 1B workers, which was pretty much everyone else with significant patient contact, and now it's being made available to level 2 workers, which are volunteers, administration, cafeteria workers, janitorial staff, etc.
Obviously, the levels have to do with there risk exposure, and risk of infecting other patients, and not their level of importance.
