Which is why our choices now are to get vaccinated or get infected with a still naive immune system (or one which didn't mount a hugely great response).

If we get vaccinated, then the risk from COVID drops to no more than seasonal flu, and will only go down with time. (Obviously, the risk is higher for some people).

In other words, get vaccinated. I'm even hearing from people who are pretty unhealthy who got jabbed, got COVID, and didn't get that sick.

Vaccination is still keeping people out of the hospital and the morgue with delta, and if you do get a delta breakthrough, it will also boost your immune system. NOT saying you should go out looking for one, mind.
