I think the biggest problem is that the front line medical people spent most of last year pushed to their limits. In the beginning, they knew so little about covid they weren't sure they were protected from it, regardless of the precautions they took. But they went in and did their job anyway.
I have several friends who are nurses, both here in Atlanta and in Tuscaloosa. They were exhausted in ways I cannot imagine. Then it finally started dying down.
And now it is back up again. The last thing I saw the entire state of Alabama had 2 ICU beds open. Atlanta hospitals are slammed. Grady Memorial, the best trauma hospital in the south, is on a diversion now. You get in an accident or have a stroke or a heart attack, they don't take you to the best place to get the best care. They take you someplace else.
The overwhelming majority of those covid patients in hospitals, and especially in ICU beds, are unvaccinated.
Once again our front line medical staffs are pushed to their limits. But mostly by those who refuse to get vaccinated. I can see where they might be a little upset. Try working 12 hour shifts and seeing the same thing day in and day out.
