Even at 80% Herd Immunity the likes of these super strains will still spread like wildfire. Israel is starting the upward trend as Delta has arrived. However nobody dies. Those not vaccinated will start choking the hospital systems.
Once we hit 80% we need to move on. The number will end up in the 90s fairly quickly as those not interested in getting the jab soon realise they will end up in ICU as case numbers are irrelevant to the large majority of the nation.
The only restriction I expect once we hit 80% is wear masks if you have a cold, in order not to pass the ‘cold’ onto family or colleagues.
However it remains to be seen how the States will start to render case numbers meaningless, and we can move on finally.
