Interesting discussion going on here. I wanted to post an update on my wife and document a few things (someone here might find them useful). She's at, I'd say, around 95% recovered after three weeks since her initial exposure.
Saturday 07/10: what we think was her initial exposure to the virus
Sunday: no symptoms
Monday: no symptoms
Tuesday: some sneezing (unusual for her but we'd had a ton of rain and mildew/mold was everywhere)
Wednesday: minor sneezing
Thursday: no sneezing, felt fine
Friday: went to work, different symptoms (fatigue, aches and pains) rapidly progressed and she left around noon (went straight to bed)
Saturday: in bed the whole day, wiped out, bad headache (I took her to CVS for a test)
Sunday: started losing her senses of taste and smell, headache
Monday: taste and smell totally gone
At three weeks, the remaining symptoms are, in order of severity: loss of taste+smell, occasional headaches, and more easily fatigued. The loss of taste+smell is still significant. She can barely taste anything. We had some buffalo wings the other day that made my head sweat and she couldn't taste anything. She says it's gradually improving, so that's good.
I still don't understand why I wasn't infected (at least, to a detectable degree). I was massively exposed multiple times during that week. I didn't isolate her from me at all (e.g. we slept in the same bed every night with the exception of one). We had the same vaccine, Pfizer, back in March/April. We went together, so it was the exact same time and batch. It's my understanding that the mRNA vaccines are pretty "narrow" which means our immune systems were sensitized to the same narrow irritant.
