As much as I support vaccination, it feels like gaps in vaccination are also used as an excuse to blow off repairing an extremely fragile public health system. We've had two years at this point.
I do agree that this is something governments ought to be looking into over the long term though.
Training people to assist Covid cases, run PCR tests, should be a matter of weeks, not years. Germany did it, I have 4 (four!) test centers on within a block of distance, all of them are filled with students and otherwise-unemployed people who got some minimal training.
If we're to treat this like an emergency, why aren't we treating it like an emergency?
Because in truth it probably never was. We assembled fully staffed field hospitals that went completely unused.
