Well pints we know for sure that will never happen...I'd reckon up to 10% of the population are anti vaxxers and would never get vaccinated, so that brings you back to 90% straights way. Then there is likely another 10% who let fear guide them and are frightened of the vaccination in case they are the 1 in 1,000,000 that has complications. In fact in this country you'll be lucky to get 70% of adults vaccinated...
So therefore under your reasoning we will spend the rest of our lives in total uncertainty with sporadic lockdowns by out of control public servants when ever a person gets a sniffle here or there,...
