Herd immunity has always been set at around 70% so that's nothing new.Well yes the vaccines are essentially experimental but hopefully for the greater good in saying that it could be a long time coming
They can keep moving the goalposts though can't they, because of the new varients. It will never get to 70% because there's always a new mutation
Then they'll say that it's ok because they can change the vaccine, but everyone that already had the vaccine before will not be covered for the new varient - and so we go on.....
