The story about why we have lockdowns has shifted over time from “we have to flatten the curve” to “cases are rising.” Masks didn’t work, then they did, then you needed two, and then none if you were vaccinated.
Herd immunity used to mean a certain percentage of the population had either natural or vaccine induced immunity. Then it was changed by the W.H.O. to only mean a certain percentage had been vaccinated.
So vaccines were sold as the means to “get our lives back” by getting us to herd immunity. Only the vaccines weren’t sterilizing so really they couldn’t ever do that.
As recently as July 7th the US President said the unvaccinated were a threat to their entire communities. As of today, vaccines have been re-redefined as simply necessary to prevent serious Covid or death from Covid in individuals.
