However, if you are CEV, presumably you are equally vulnerable to other endemic illnesses like chickenpox, flu etc. Is there reason to think that this will be worse, do we know?
Chicken pox - I've had as a young teen, before I was vulnerable due to being immunosuppressed. It's much more unusual to have it a second time.
Flu - only knowingly had once, though may have had it asymptomatically. Was poorly but not bad.
Cold - have several. Only once has it been really bad - led to pneumonia and being pretty poorly with hospitalisation, several weeks off work, lengthy recovery after that.
Covid - led to a complication that put me at a high immediate risk of heart attack or stroke, rushed to hospital where I was admitted for a short while, lifelong condition now with two different tablets taken daily, for life, to ensure it's under control. This new condition also would make me more vulnerable, on top of the previous stuff. Was off work for several weeks. Have long covid and 15 months later I still struggle with breathlessness, chest pains, fatigue, etc and my iron levels are now low needing iron medication to try and improve it a little,
I'm not CEV. I am borderline CEV/CV, been shifted between the two in and off. I am eligible for a 4th vaccine due to health condition and medication, due next month. Work in close contact with nearly 300 children and staff each week, no mask etc anyway - it's almost certainly where I caught covid. Currently school is really struggling. We now have over 20% children off with it, even more where household members have it but so far they're negative. I'm hoping to avoid it this time round, fingers crossed.
