That goes back to (probably) what the WHO will come up with in due course. The WHO decision making process is quite slow and I imagine this is very low down their priority list. Hence those places which are vaccinating a lot - many such places are also Covid hotspots - will perhaps want to move faster. So that would be the UK, EU+EEA and Israel as things stand.
