KennyG. Where will it end goodness knows! Looking at how the Gvmt react to new variants I wonder if anyone has considered that, as there are some 200 countries in the world - and goodness knows how many isolated societies like islands- there could ultimately be hundreds of variants. I forget the name of the doomsayer scientist who predicted that we will be playing catch up with covid for a very long time. Probably just until a more fatal strain of infection - say dipper crossed with scum appears.
