Alexander Morgan33 said:I had a confirmed case of COVID-19. Up until the day my symptoms showed up, I was sharing a bed with my boyfriend. We’ve been sleeping in separate rooms since then. We didn't go overboard disinfecting everything constantly. His antibody test came back negative.

Either you guys managed to isolate yourselves well enough that he didn't catch it—or maybe his immune system is just incredibly strong.
Andrew Booth29 said:A lot of people seem to possess immunity driven primarily by T cells—it’s a different mechanism entirely. In these cases, the virus simply fails to trigger a severe enough reaction for the body to bother producing antibodies. Essentially, cytotoxic T cells step in and wipe out the infected cells before the virus even gets a chance to replicate effectively.
They’ll likely end up testing positive on a PCR test, sure, but they almost never actually show symptoms. Most people who experience those mild, nagging symptoms don't even develop antibodies. It’s usually the ones with moderate issues who do, and then you have the severe cases—those folks almost always produce them.
Personally, I’ve seen plenty of live examples of this, so I guess the only rule is that there aren't any rules.
I just lost my sense of smell and taste, but I do have antibodies.
A colleague of mine from my office—totally asymptomatic—has three times the antibodies I do.
Then there's a younger colleague who just had a headache and some fatigue for two days. Yet, he has enough antibodies to look like he survived a ventilator.
Another young female colleague spent four days with her husband before it turned out he had COVID-19, so they split up. She didn't catch it, and she doesn't have antibodies.
