From Dr. Sessions (StTwits):

Exposure to the endemic coronaviruses produces immunity that lasts longer than influenza, but not permanent immunity. Coronavirus (CV) immunity is moderately transient. CVs are also fairly poor at maintaining the integrity of their genome, which has the effect that it can mutate frequently. That's why the CV-related common cold is recurrent; mutations and transient immunity.

This is also a reason that CVM LEAPS is a better option than a traditional antibody mediated vaccine. LEAPS targets antigens within COVID-19 that produce T-cell responses. Unlike the mechanism behind antibody based vaccines, these antigens are less variable between viral strains and less likely to change in response to antibodies elicited by prior infection, or other vaccines.
