I wouldn't bet on "solid" evidence for a while. Hang around the /r/covid19 subreddit for the latest data. There have been very few reported cases of someone getting it again and of those a lot of evidence points to relapse rather than reinfection. Given the large # of cases and their high concentrations in specific places, it seems likely that we would see many cases of reinfection if previous patients weren't immune.
