The current answer to me seems to be that we do not know one way or the other. The hope is that it will but we are just now starting to get some data on how effective vaccines are at preventing transmission (Pfizer seems effective, others have no conclusive data AFAIK), we don’t know what herd immunity actually is (Fauci estimates between 70 and 95% vaccinated; 70% is possible without vaccinating children, 95% is not. In the US you have enough anti-vaxxers to prevent herd immunity from ever happening even at 70%), we don’t know how long the vaccine is good for (current estimate is at least 6 months but no clue if it is more), and we don’t know what other mutations will show up. The peachy scenario is that we vaccinate everyone super quickly while keeping social distancing and masks to not have any new variants develop and herd immunity can be achieved with very low percentages. The other scenario is that we take our time, dozens of vaccine resistant variants pop up in the meantime and it never goes away because a virus can mutate and spread more quickly than we can play whack a mole.
