We might have to, there is no guarantee that mRNA vaccines or lockdowns will ever stop covid to to point where no one ever gets hospitalized with covid.
This is the inconvenient truth that absolutely nobody in the establishment is even remotely willing to even consider and a big part of the debate that is being replaced with an accusation contest.
What do we do when the vaccination program only works as promised by the scientists developing it, and not as hoped for by the politicians ordering it?
This season isn't finished yet, but we are seeing far fewer people sick and dying than last year. This trend is bound to continue, even if vaccines fail, if for no other reasons than the herd getting thinned out, cynically speaking.
Covid will stop being a concern only after safe and incredibly efficient antiviral drug is developed, which might take decades.
