Household transmission being weird

[applejumble]

DH tested positive on Saturday. So far no one else in the house has caught it. We haven’t been isolating from him at all. (Small house). I’m treble jabbed and have had booster. Three kids too young to be vaccinated. What’s going on? We saw DH parents and siblings the night before he tested positive and non of them have it either.

We’ve never had household transmission either. My 7 year old tested positive at the beginning of December, nobody else caught it. My 14 year old then tested positive at the beginning of January, nobody else in the house caught it. I spent less than an hour in the same room as my 9 year old niece on Saturday, she tested positive on Sunday and I tested positive on Tuesday so must have caught it from her. Nobody has caught it from me yet but we are only two days in so there is still chance yet.

Me and Dh are triple jabbed, the 17 year old is double jabbed and the 14 year old only managed one vaccine before having a positive test.

Day 9 here and only DS has it out of 5 of us.

My dc have spent months sitting in classrooms rife with covid. Their friends they play with have tested positive, and yet they've managed to avoid it despite multiple outbreaks throughout the year.

Dh went to a work meeting in the office early last week. Subsequently everyone in that 2 hour meeting tested positive, including dh (positive lft on Sunday). Tuesday ds and I tested postive. Dd so far remains covid free.

Dh and I are both triple jabbed. DS and dd are too young for vaccines.

DS caught it, the rest of us in the household never did (two adults triple jabbed), neither did my DD who had no vaccines. Tested for 10 days to be on the safe side. Also did PCR on day 5 just in case, all negative. It completely changed my perception of cocid as I thought it is so transmittable, it is inevitable we were going to get it! DS had temperature for a day, no other symptoms. After he fully recovered, he came down with a cold which I also caught. Go figure!

I had it 3 weeks ago, caught it from someone I looked after at work (I assume). I was asymptomatic, DH and DCs didn't catch it. I was one of the lucky few who tested negative by day 6!
DH tested positive on Monday night just gone, he's suffering a bit but not severely.
I've had a sore throat since Monday too but so far negative (no idea how likely its be for me to catch it again this soon anyway!) and DC also so far negative touch wood.

How did he not catch it from me when we slept in the same bed and I did all the cooking etc, distancing not possible in our house, but he's now caught it elsewhere?? Blows my mind

All my kids tested positive on the same day (and all of them tested negative 48hrs earlier). I'm convinced one of them caught it first and gave it the others - chances of all 3 picking it up at school at the same time seems low (different schools as well).

I tested negative until 8 days after they'd tested positive. I was continuously in close contact with them throughout. Don't know if being triple vaccinated helped me fight it off for a bit longer or some other random reason, as incubation period for omicrom claimed to be between 36 and 72 hours

Update... DS is day 10 and DD has just tested positive (2nd time for her). She could have caught it at school as has been going through her class

My ds had it 3 weeks ago and I didn't get it. Not vaccinated either. Assume my immune system dealt with it. There are more and more studies being done on t cell immunity now as antibodies clearly aren't the answer since they're so short lived. These studies have shown that between 20-50% of subjects had t cell responses to Sars Cov 2 having never previously been exposed which would suggest that many of us already have immunity.
