If it follows the pattern of other Corona virus immunity, you'll build antibodies against it while infected. If you "recover", those antibodies will afford some protection for a year or so against the virus that you survived. It won't be a life long immunity. You're at risk again when it fades.
I’m pretty sure I read a piece in the daily thread yesterday that CCP-19 is not conferring immunity.
Not only can you get it again, there are several strains of it now, and you can be infected simultaneously by them.
This beast was engineered.
Whoever did this needs to pay.
