I'm predicting a bit longer until laws start passing that mandate a legal requirement for all to get vaccinated for covid-19. I'm still unsure how long that will take, for it to come into law but I assume the vaccine will be pointless for stopping the virus spread and until everyone is being vaccinated. Basically, the ones that firstly get vaccinated will have to continue doing so until everyone if forced to follow. I could be wrong but I assume people not getting vaccinated will keep the virus going host to host and until the vaccination wears off; requiring another one and repeat.
