I vaguely recall a previous story where there was a good medical reason why the person in question didn't have a lasting immune response (another procedure / therapy / condition or something). I can't imagine that would be the only case like that.
There's no reason to think immunity won't be similar to SARS-CoV or influenza. We never developed a vaccine for SARS. We already know that nearly everyone who recovered from SARS had some immunity to it for some useful amount of time. Otherwise the earlier SARS-CoV would have been worse than SARS-CoV-2 and it would not have burned out as quickly as it did.
SARS was much more containable as I recall due to people presenting with symptoms promptly and a lack of asymptomatic transmission.
Durability of the immune response will be an ongoing question but for the purposes of deploying effective vaccines so far it looks like it's not going to be problematic like if most people could be reinfected after weeks or months. Vaccines might also produce longer lived/more robust immunity than a mild case of infection
