Why would they take a covid test if they believe they are immune?
My wife and I have been fully vaccinated since May, but we've had several tests since then (so far all negative) when we learned about contact with infected people or were experiencing suspicious symptoms.
I'm vaccinated but had no idea I had such representation on HN, I believe you should speak for yourself sir.
That's been the weirdest part of this whole business for me... learning just how many people simply don't care if they're wrong.
