Since all the vaccines are aimed at one of the two proteins in the spike, and there is only one point mutation in one molecule so far, it doesn't matter. Since the spike has to fit with the ACE-2 receptor, it can't mutate too much and still work. So any antibodies against the spike should continue to be effective. Any mutation that could evade the antibodies produced by the vaccine will render the virion incapable of entering a host cell.

@papawheelie5576 Wrong! A successful vaccine for SARS was finally developed, but by the time it was vetted by clinical trials the epidemic was over. That development hastened the work on this similar virus.
