If you can get reinfected, there's a good chance that the second infection will have a particularly high mortality rate, because this virus likely has a property known as antibody dependent enhancement[1]. Long story short, your normally protective antibodies actually work for the infection. This was a property of past coronaviruses like SARS and is likely why no vaccine was successfully developed.
