Oh, I don't know. I'm seeing plenty continuing the EU and I think some may do it in perpetuity.
I think it is all some of them have, in the way it has become a core part of their identity and so if they lose it, they lose something of themselves.

It's quite a good site and presents a multitude of data across a variety of countries.
The data set I referred to was countries that have given the full vaccine e.g. if 2 or more doses are required.
I think this is an important distinction as the UK have decided to delay the 2nd dose for many despite WHO and manufacturer advice. In short, it looks like the UK is rushing their vaccination programme because they took such a poor approach to stemming the spread of the virus in the 1st place.
