Actually it is true. If you're 50 and over and work at any of those places, you may have the first dose or your appointment booked. If you're 40+ and were able to find a place offering it, you may have gotten your first dose of AZ. If you work in a hot spot, you may be however many in schools have not because they are under 40, don't work in a hot spot or were unable to get in to get the AZ. So totally true.
