Yes, very strange. My girlfriend and I did zero isolation and she tested negative for 5 days after my positive, never had any symptoms. A coworker who was exposed by the Iceland trip coworker was floored for about 4 or 5 days. Same age as me and same vaccination status.
I'm pfizer triple vaxxed. Got my booster back in January. I don't know, but I'm glad my case was so mild.
given how miserable that first night was after feeling off that morning (maybe 2 hours of sleep), especially while on vacation... ugh. i wouldn't say i wish i was boosted, cause it's still like whatever, but if getting boosted would've for sure eased the misery of that first 48 hours and cut down the weeks of exhaustion, i woulda for sure been in line for it.
