I was referring specifically to Omicron, so both of your links aren't really what I was looking for—thanks anyways.

My main surprise was OP's assertion that medically necessary supplies such as blood had run out during the last surge, but so far this seems unsubstantiated. As you mentioned, I was aware masks have been in short supply at points throughout the pandemic, but blood and masks aren't quite equivalent.
