There is a suggestion neither will happen (at least, usefully):

immunity to covid 19 could be lost in months uk study suggests

But, so what - it'll be just like flu or a cold. Except that dying may not be the biggest problem:

as covid 19 persists around the world death is not the only outcome to fear



In a war, the most effective weapon is not the one that kills your opponents but the one that maims them and ties up your opponents resources.

Confirmed

The Hospitalet(Barcelona) rest home already accumulates 10 positives, five of them reinfected.

It's true the number of antibodies fall drastically after recovery, but we don't how many antibodies are required for immunity? I'm not an immunologist, but I do believe the immune system does have some sort of memory and will produce antibodies much more quickly, if it encounters the same antigen again, so the same level of disease is unlikely next time.

Immunity will decline over time, but at the moment, it's commonly believed it will last for at least six months. I'd be very surprised if it wanes much sooner and if people who've previously had severe COVID-19 get reinfected, it's anywhere near as bad as it was the first time. Of course this is a new disease, so I could be wrong. This is a coronavirus, which is related to the common cold and there is no vaccine for that, although that could be that colds kill only kill people who are already very immunocompromised.

I can't read Spanish.

These is the first cases of reinfection I've heard of, so I question their validity.

Are these genuine reinfections, or lingering dead virus particles which have been picked up by the test? I've heard plenty of reports of people testing positive again, after recovery, but so far, they have all turned out to be the latter.

Suppose I'm wrong and those are reinfections. What do we do then? Can we really keep social distancing forever?

You obviously haven't been looking, then. You can question their validity, but there are plenty of reports. There are also reports of studies of antibody measurements after people have recovered, showing the antibodies seem to tail off quickly.

Biology isn't my "bag"...  so, do we keep getting the common cold because we lose immunity, or is it because the common cold keeps mutating?

A combination of things. There are numerous viruses that cause upper respiratory diseases collectively referred to as "the common cold".
