My family is 100% double or triple vaccinated over the age of ten. I and my wife are the only doubles, and that's purely for logistical reasons - I would have had the booster if timing had been right, and I will have one later in the year.
Of the ten of us, all have had symptomatic COVID in the last three weeks. The sole exception is my three year old son, who is not vaccinated (he's three), but who may have been asymptomatic (his 1 year old sister did have symptoms).
Other than my 78 year old dad, who is an old hand by now, it was the first bout for everyone, including my brother and his fiancée who are doctors but have remarkably not had it yet.
As for literal results - it's been pretty mild, for which I think we can thank the double and triple vaccinations.
