1. If you are healthy without underlying conditions, mostly nothing.
2. only for some. Mostly, elederly and those with 2 or more underlying health conditions. What some would refer to as “chronically ill”. Frail people can die from many things, like falling and breaking a hip can be deadly with diabetes and other chronic illness. But we don’t ban walking for the whole population to prevent it amongst the high-risk.
3. That’s not the point because Delta variant spreads the same wether vaccinated or not. See one of the world’s most vaccinated countries, Israel. Besides, hospitals get overwhelmed every season of whatever, or even during bad single events like big fires or accidents.
Nobody builds big expensive ICUs to just sit empty
most of the time. But we make due in large scale events anyway just fine. You prepare for reasonable scenarios, not every possible scenario. Otherwise, we would never leave the house without a helmet and full body armor, with an emergency med kit and defrib strapped to your back. You know, just “in case”.
So please just accept that this is endemic and something we will learn to live with like the flu or the common cold virus. Life is meant to be lived with risk, not with zero risk; that’s called existing, not living. Imagine if we ran aviation with zero risk. We would never leave Kitty City, the bus ride to the jet is the deadliest part of the journey FFS. 🤦♂️
