I was listening to an interview with an antibody expert, although I've forgotten where.
It's indeed not great news that antibodies only stay in the blood for 2-3 months, but apparently, it's not quite as simple as this.
Although antibodies may disappear, in other cases there is often a kind of memory effect for mechanism that produces the antibodies.
This means that the body is able to mount a defense much more quickly the next time it encounters the virus.
This being said, we don't yet know how long and to what extent immunity lasts for covid-19
I heard a news report of a person who got the virus, had mild symptoms for two weeks, fully recovered with no symptoms for the following 6 weeks, and then contracted it again with more severe symptoms.
