I think it may be possible for some people to get infected again. It is likely dependent on an individual's immune system, which has immense variability in the human population. Single anecdotes should be interesting points worthy of follow up. But I don't think reinfection is likely to be a major driver of the pandemic. And most importantly, any second infection would almost certainly be less severe than the first one. If the immune system fought it off successfully once, memory cells will aid the response to a second infection. Perhaps someone who is very medically fragile, and in whom any viral URI could tip things over the edge, would still be at risk for a poor outcome. Hence nursing homes should be a key focus of high level PPE usage and testing of staff and residents. But I think reinfection in general should be a low level concern with the pandemic, and I have not seen any actual scientific literature showing it has actually ever occurred.
