So I don't know if he is saying that lockdowns will "generally" continue on a global stage remain until 2022, or if he saying that there will be lockdowns "somewhere" in the world into 2022. Initially I take this to mean the former because of this statement in the article: "BILL Gates predicts global Covid-19 restrictions could last until 2022".

If this is the case could someone explain the reasoning here? The UK is expected to complete its vaccination program by April 2021 [1]. I can't imagine other Western countries will be very far behind them. I imagine the isolated nations such as AUS and NZ will allow travel with the necessary vaccination certificates [2].

I feel like I'm missing the link as to why lockdowns dragging on to 2022 is likely?
