COVID-19 Outbreak Information Updates (Reboot) [over 150.000,000 US cases (est.), 6,422,520 US hospitilizations, 1,148,691 US deaths.]

So now that my family's extremely-mild case of covid has come and gone, what does that mean for my wife and oldest daughter who both never tested positive (both fully vaxxed, wife boosted)? Are they super-immune? Or just abnormally lucky? It still shocks me that they never tested positive, as we took zero in-house precautions/quarantine measures while I and my two youngest were positive.

I guess my real question is... should my wife feel confident "out and about" since she has now stared covid in the face and said "no"? Not that she is hiding away or anything, but there is a certain amount of emotional and mental freedom that you feel after clearing a mild covid infection.
