I'm a teacher, I've had it twice and even though I'm the wrong age / weight to be getting it - no, I'm not anxious at all.
Use your teachers' brains to understand the stats and read beyond the media scaremongering! 
That's fine and I'm glad you were fine.
But catching covid 15 months ago put me in hospital.
I am CV (in and out for shielding, need to have 4 jabs, etc) work in close contact right across the school and covid led to complications. I now have a life long additional medical condition as a result, along with daily medication for life. I'm diagnosed with long covid. 15 months later I still have some ongoing issues such as fatigue, breathlessness, chest pains, etc. This is on top of my previous health condition and medication which puts me in the vulnerable group.
I was fortunate in that I was able to work from home during the two school closures - more due to my specific job role than anything else. But once I returned between the closures I caught covid. All the timings etc point to it coming from school - it was rife in the school at that point, with approx 80% of our staff catching it (despite not being in close contact with one another) along with many of the children and their families.
I'm now triple vax, with 4th vax due in February. I'm still working right across school, so in close contact with 300 children and school staff each week. I do what I can but there is only so much I can realistically do.
I don't want schools to close. In the school lockdowns, despite being at home, my work load was immense. I'm not sure I could do it again.
I also don't want to restrict my life outside of school much more either. I take precautions. I wear a mask. I distance where I can. Despite cold causing me pain I meet friends outside where possible or with windows open for periods of time if indoors. I lost too many family members in the first half of 2020 (not covid but made much harder by covid restrictions) and being able to see my close family is important to me.
I don't think there is much that can be done.
The government won't pay for filtration systems and other such precautionary measures, and schools don't have the budget for it, so that's a no go.
It's primary so masks in classes aren't appropriate and social distancing for the children is impossible.
My headteacher is trying to find solutions to me reducing the number of contacts I have, but it involves logistics and timings, and other staff, so not ideal and not a longer term solution.
I don't want to give up my job. I enjoy it. I'd be bored being home all the time without working. I need to work for my sanity!
I just have to have my fingers crossed that if I get it again this time the vaccinations will help keep me from complications and hospital admission.
And hopefully we are heading towards the end of the crisis gradually and we can start to live with it becoming a milder and less concerning virus.
