Sorry, I did not answer sooner.
Yes, if any Covid-19 virus vaccine does not work we are in trouble. The good news is; even though coronaviruses, including the one we are dealing with, do mutate, this is usually not a problem.Emphasize usually. Flu viruses also mutate but the problems with the flu viruses are that the protective vaccine immune reaction only lasts roughly six months. Also there are multiple different flu viruses and the vaccine companies have to “guess” which ones to make each year.
There is too much we do NOT know about Covid-19. It is more likely to recur in the fall than not, but nobody really knows
It is also unlikely a Covid vaccine will be ready for the fall. But one can hope.
