Not an epidemiologist, but my understanding is that the reason Covid-19 was so bad, and the vaccines took as long as they did, was because there was no vaccine for anything close to it before (it's similarish to the common cold). A mutated strain, even if it makes it more infections, is still relatively better than a wholly new disease because the existing vaccines might already be partially effective, and will be the basis for new vaccines to attack the specific strain. This means that even if the current speed of vaccine development is outpaced by mutation, that gap will close as vaccine development for specific strains will be quicker now that there is a Coronavirus vaccine. People tend to get flu shot's once a year, and I imagine worst case scenario, people will have to get Coronavirus vaccines around the same time.
