In short yes it can be the likelihood of death is much lower but you can still get pretty sick from its effects. Which may or may not require medical intervention. With or without a vaccination long covid can not be ruled out the effects of which are still not fully understood.
I hear ya. 👍
But... I am of an age (66) where every year I stand a risk of catching and dying of flu or being diagnosed with some later-life end-game disease and tbh if I didn't shunt that into the background my life would be bereft of a certain amount of happiness.
I am fully up to date with covid and flu vaccinations, I stay as fit as I can and eat as well as I can - and that's all I'm going to do.
NB: in 2016 I was misdiagnosed with Motor Neurone Disease which lead to deep depression - once I got clear of that difficult time I vowed to just crack on and not fret about what may or may not befall me on the health front.
The above probably explains my stance on the Covid front.
And, as my GP said 6 years ago; "live long enough and you are almost certain to be clobbered by something horrible".
So... why worry?
