There's nothing positive OR negative yet on herd immunity. In animal tests, reinfection did not occur (
link note, preprint and not peer reviewed) This gives some confidence.
There is clinical evidence that patients who tested positive and recovered tested positive again but it is not clear if this is a reinfection or a reactivation of the virus. There are growing suspicions that the sensitivity of commercial tests might be causing at least some cases of reoccurring infections (

There are a lot of unknowns here and when there are unknowns, there are risks
