We are likely to be at this whole social distancing for a while yet. The vaccines are making good progress and I think we will see at least one approved in time for Christmas.
However, roll out will take a good while longer as at-risk groups are rightly prioritised. I can see March before I can get a jab - and I will get one - with social distancing measures lifted gradually over the course of Q1 2021. At which point patience will have run out - it's already getting pretty thin.
Getting the world vaccinated will likely take longer; the manufacturing capacity just isn't there. It may easily be 2023 or 2024 before we get global 'herd immunity'.
During which time people will continue to get this illness and die of it. The WHO representative who estimated two million global deaths yesterday is being sadly realistic.
