Within my family most people haven't had it. Some have had antibody tests to see if they've had it asymptotically and don't have virus acquired antibodies, only vaccine acquired ones.
I had it last October.
Dh and 19y dd haven't.
Dd has been in close contact with it several times through me and her university and home friends, but has not yet caught it.
My parents and MIL haven't, neither has my sister, BIL, 8y nephew, brother or his fiancé. One niece has had it but the other hasn't. Their mum got,it but my bil didnt.
With friends, friends inc intact with us when I got it didn't catch it then. One friend has since had it recently but his wife and two daughters didn't. Another friend's dd has it now but she, husband and teen dd haven't got it yet. Another set, wife caught it earlier this year but not husband. A few friend couples who neither have had it.
At school almost 80% of our staff have had covid, most last autumn term. One or two have had it this year. Nine have had it a second time as yet.
