And, even if there was anything, what is anyone meant to do, exactly?

HEPA filters in schools, busy public buildings etc
Fresh money for better vaccines
More testing, at least in places like hospitals

Lots of shit can be done with minimal effect to ever day kfe. Yet nothing is done and everyone pretends covid is over. Yet, it's pretty much clear that even one infection increases the risk for dementia, Alzheimer, strokes , diabetes and pretty much everything. And everyone gets infected again and again and again every 6 months. The next couple years are gonna be interesting.
