Phase one complete, for me. I’m not long back from the vaccination centre (a vacant unit at the Westfield shopping centre, slightly weirdly) where I got my first dose of the AstraZeneca Covid-19 vaccine. I can feel my immune system surging, boosted with superpowers, and a strange, unearthly calm descend upon me.

I exaggerate. But it feels pretty damn good to have taken this step. I don’t get the next one until June, and it’s not like we’ll be out of the woods even then; not even personally, and certainly not the country or the world. Especially given the panic over a statistically meaningless set of blood clots, and the news today that the UK’s supply is going to be temporarily constrained.

But considering that it’s only just over year since we learned about this virus and the terrible disease it brings, it’s worth taking a moment to celebrate the scientists and doctors who were able to develop the vaccines so quickly. Not to mention all the NHS staff who are getting it to people.
