Granted, the mRNA vaccines can be tweaked into boosters for mutated strains of the virus, but that takes time. If a mutation like the B117 strain is equally or more transmissible, and overcomes existing vaccine/antibody immunity, the pandemic could be global again (at the same or worse levels) before new vaccines are available. That's why getting as many people vaccinated as quickly as possible is important.
