I've had Pfizer and one booster last year. I've been exposed to COVID a ton of times in 2.5 years but never got sick or tested positive—until last week. The bastard finally got me. It spared my husband (though he had it in May when he returned to Australia for a visit).
My symptoms were pretty mild, but most of my Aussie friends and fam have had it now, and they were all pretty sick for a few days.
It's certainly an elusive virus that you just never know how you'll react.
Wishing you and your fam a speedy recovery, Tim!
