The government’s latest prediction is that our lives will “start returning to normal” by Easter 2021. After a flurry of hugely encouraging vaccine trial results – the Oxford/AstraZeneca candidate could be up to 90% effective with the right dosage regimen – there is better reason than ever to be optimistic. Now the question is when, not if, life will return to “normal” – whatever that is.

But we’ve been here before. In March, Boris Johnson was confident that “we can turn the tide” on the virus within 12 weeks. In July, he predicted that we’d be back living our ordinary lives again by Christmas.
