We don’t always keep making antibodies for things once we’ve cleared them. We have memory cells that will ramp up and make them if we encounter said antigen again.
Up to this point, there hasn’t been proven reinfection that I’ve seen or read. That would go against everything we have so far in virology for the most part. Immunity may wane but I would imagine it’ll last atleast a year or so and even then you may be able to get it again but it would be very mild
