I haven't had it, so far as it's possible to know. The antibody tests aren't accurate for very long. I did have such a test at one point, and it was negative but the medical person testing me acknowledged it proved nothing.
I find it astounding you're not aware that people can get this over and over again. I also find it astounding you're unaware of the serious side effects that affect people even after mild or asymptomatic cases.
I feel people are ill-informed about this in general. It's worth educating yourself about it. There's lots of information available online. Read reputable reports from legit sources. Stay away from the right-wing nutcases.
