A scary prospect when it comes to herd immunity & a vaccine: coronavirus patients might be susceptible to re-infection

There is a small but growing group of COVID patients who were likely infected, and then re-infected.  If re-infection from the virus turns out to be a possibility, that makes developing a vaccine awfully complicated........and also dashes hopes for the idea of herd immunity.

And more bad news:  the second infection appears to hit people a lot harder than the first.
