The Anglo-Spanish connection is getting stretched to breaking point by Brexit plus the pandemic. A woman in my online Spanish class missed her vaccination appointment here as she wasn't allowed to fly into the UK from Spain, although a UK citizen. She'd been visiting her Anglo-Spanish family in Spain and is still there.
In my family we've done a lot better. I had my first jab on 21st December and my wife gets hers on Sunday. I'm not happy, though, about the postponement of my second jab, originally scheduled for 21 days later on 11th January, following the government's change of policy. An immunologist I heard on the radio said his colleagues in other countries were "aghast" at this step.
