All the vaccines that I've seen (RNA or traditional) provide immunity against the so called spike protein. The spike seems to not mutate, since it is the protein that is necessary for the virus to enter cells. It is likely, therefore, that the vaccines will be effective even against more virulent strains. If that turns out to not be true, then we're in worse trouble than we thought, but the odds are low, so I don't think it's a time to panic. I've even seen conflicting evidence that the UK strain is that much more transmissible, so it's possible this is a better-safe-than-sorry situation right now. Let's hope so.
