From my Stanford connected doctor. He of course did not mean this as definitive. Just as the state of our current knowledge....

“Molecular studies of Coronavirus indicate that the virus does not substantially mutate (in
contrast to the flu, which mutates rapidly).  Therefore, a one time vaccine for Coronavirus may be
sufficient to last for multiple years, and a yearly vaccine (like the flu) will probably not be necessary.”


His reference to Coronavirus refers to the current one. 

No way for him or her to know that yet. Is he or she an immunologist or an infectious disease physician who does research at Stanford? Stanford "connected" doesn't mean much. My Stanford connected doctor seems to know less than I do. We don't know if an effective and safe immunization will be easy to produce, difficult to produce, or impossible to produce. We don't know how long it will be effective if it is developed. This virus has been mutating slowly, but what really matters is how much change occurs in the portion(s) of the virus you decide to target with your vaccine. Vaccine development is fraught with pitfalls.
