Covid won't ever go away so you will need to make a decision as to whether this is how you will live your life or not.
I'm classed as being vulnerable. I have had 4 vaccines and I am eligible for antivirals if I have covid. I shielded initially and then was moved to group 4. Then back to the higher group when it came to the extra vaccines and medication.
I teach primary, with little children so I am in regular contact with covid. There has never been any social distancing, etc, due to their age so my choice was, after lockdowns ended, go out and mix or stop working and hide from it. I did the former.
I've had covid twice whilst being classed as vulnerable.
Yes, I was ill and I did have some complications the first time, but that was pre vaccines and a more worrying variant than we have now. And ultimately I was still only a 'moderate' case. I went into hospital for repeated complications (it made my blood pressure spike) rather than the covid related breathing issues. I wasn't in high dependency, icu or needing oxygen/ventilation.
The second time (3 vaccines later) I had antiviral infusion in day 5 and it was a game changer imo. Within 24 hours from that medication I went from being a very strong positive, feeling rather poorly, breathing issues in doing anything, etc to feeling so much better and testing negative in LFT.
Both times I caught covid from school during big outbreaks, so there'd have been a high viral load from numerous close contacts in poorly ventilated over crowded classrooms,
Dh and dd did not catch covid from me despite us not social distancing at home. When dh (3 vaccines in, fairly mild, ongoing cough but only felt 'heavy cold/flu like' poorly for 2 days) had covid more recently I didn't catch it from him either. I've seen this lots - household members not passing it in. So there is a chance that even if you caught it she may not.
