Seems like in these people, paxlovid is beating it down and when when they go off the drug, their immune system doesn't finish the job for whatever reason.
@Le Petomane I'm not sure why the 5-day course of treatment was chosen. I think back to ages ago when I had a dental infection. They would give me a short course of antibiotics, book an appointment a few days afterwards, discover I still had an infection and repeat. I know they try to limit antibiotics for just these reason but 2 short courses followed by a long one might have been part of the issue.
I have since found that I react better to sulfa-based antibiotics.
