Everyone in the below post is vaccinated and boosted (where applicable)
Anyway:
My wife is a nurse and lasted up to the summer before finally contracting it.
I was recovering from serious medical so she couldn't really isolate. Neither the kids nor I contracted.
Seperately my mother contracted but my father never did.
My sister and her family have had it several times.
Now we may all have been asymptomatic and had it without knowing but, assuming we were not, how many others are in a similar boat where they've been in immediate contact for extended periods but never contracted?
