Considering I had the damn thing in January, why would I?

The notion that this virus wasn't here until March is not proven.

Because it's unclear how long antibodies last. Unless you've had a positive antibody test it seems like a reasonable measure to protect people around you.

Immunity is more than just antibodies

[Pfhreak]

Yeah? You are suggesting you could be immune but show negative on an antibody test? How?

[akvadrako]

T-cells. Or genetic differences that make you naturally immune.

[mlthoughts2018]

Or just false negative of the test itself.

Did you test positive for covid in Jan?

If not, it's not proven you had it but you supremely confident.
