Yeah I don’t think the goals have been clear, even if they have been changing over time. I think the clearest goal now should be a 90% vaccination rate to turn Covid into the common cold, and then going back to life as normal, but as long as huge swathes of the population refuse to get vaccinated this goal is unattainable.
Edit: I believe Biden actually set a 70% vax goal for July 2021, and we missed it. No way we can hit 90%. I think possibly for anti-vaxers their goal is simply to not be told what to do and if they end up in an overwhelmed hospital so be it.
