You wanted to sound the all clear based on your experience. I am saying you should go ahead and let that lone Israeli minister in on the memo that your antibodies protected you (from a person of unknown infectivity).
Everything in context. I responded to your post saying that:
Just about everyone agrees at this point that antibodies work (for some time).
Showing you an example of those those that disagree.
What assumptions did I make? I *asked* but did not *assume* whether you are confident the guests do not have COVID. If you’re sure, than clearly you have no proof of antibodies offering protection (which you inferred). If you’re not sure, then it was dangerous and wrong to host people from a virus hotspot and potentially introduce new infectious people into CH (against the clear advice of the *local* medical establishment).
I really think you can use a vacation. You supposedly ask a question, and don't even wait a NY minute for a response (not that one was really that essential, all you had to do is go back and read your quotes and try to find which verbs you attribute to others without basis).
While you might not know me personally, I think I've posted quite a bit on DDF, so you might have figured out that guests are rarely invited to my home. As a matter of fact this past Pesach was a rather unique time (with the Yeshiva closed) where we actually invited some guests. Otherwise our house operates on a כל דכפין ייתי ויכול without any requirement for those that wish to enter our doors to be hungry.
