Covid attacks the body in ways scientists\doctors haven't ever seen before and they still don't have a firm grasp on it. Everyone certainly hopes we have long lasting immunity but if this virus behaved like SARS1 it would have died out months ago.

It's still a virus and our immune system reacts to it like one.
At this point, I'm very confident that the vast, overwhelming majority of folks who have gotten it are safe form reinfection for a good amount of time.
The difference between SARS1 and SARS2 is that SARS1 had a quicker onset of symptoms and didn't have pre-and-asymptomatic people walking around infecting others around them. It was much easier to contain as a result. As far as I know, it wasn't due to the immune system response.
