Child hospitalizations are spiking. Did COVID lockdowns create 'immunity debt'?
Hospitals are reporting never-before-seen surges in children with severe viral infections that are pushing critical care beyond capacity

It's interesting and of course it's kind of intuitive - lock people up and they don't get sick, and when they get out of lockdown we'll see illness spread faster than it would have due to a lack of immunity. Which means not only will more people get sick because there's no natural herd immunity to slow the virus down, but they'll all get sick at once. Which appears to be what's happening.
I think it's something gov'ts will have to start thinking about and weighing if they ever look at lockdowns to address a pandemic again.
