Recovered patients from SARS-1 had long-term antibodies in good concentrations until about 3 years after the infection. We can expect about the same since both coronaviruses are so similar.

Maybe we will end up putting this new vaccine research to good use and see if we can knock out some of the other coronaviruses. I'd love a combo vaccine that immunized against a bunch of common cold variants.

Even if you recover, there's not a lot of evidence now as to what the duration of immunity will be. With this spreading through the world at different paces, it means that, as commonly predicted, we will see continuous re-emergence as we do with other cold viruses and influenza.
