I hope you are right about the more effective vaccine. However it depends on how fast the virus changes.Our current vaccines for Covid helped slow down the spread, but they are not 100% effective to be sure. My guess is there will be more effective vaccines eventually.
Our flu vaccines have never done much better than 50% effective, even though they are improved every year. New flu viruses and old ones changing is the problem.
