All viruses mutate; RNA viruses (of which SARS-CoV2 is one example) mutate faster than DNA viruses.  It seems like the mutation rate of SARS-CoV2 is lower than influenza.  The fact that it mutates doesn't necessarily point to loss of immunity.  Loss of immunity to other coronaviruses happens because antibody titers against the virus drop to levels where they no longer provide protection, not because the antigen to which you have antibodies has since mutated.

I will say what I've said before. This is a new virus and we don't have all the data. We should not draw overly definitive conclusions based on what we know about similar viruses and the limited information we have to date.  It's ok to speculate, but don't jump to conclusions.
