I am 45, which means I’ve now had my third Covid vaccine. The experience of getting that injection crystallises a thought: Britain is starting to take the miracle of vaccination for granted, and that spells trouble for Boris Johnson.

I don’t use that word ‘miracle’ lightly. The development and distribution of working vaccines with such speed and scale is surely a historical event, and one that should give both big-state left-wingers and the free-market right pause for thought, since it relied on the partnership between public and private.
