Well thanks for the link to the vaccine booking site. DM is now booked in for Wednesday

. And I'm planning to go visit her at the start of March.

- She was in a support bubble with DSis, but hasn't seen her since Christmas, so all entirely legal, but feel more confident visiting once she's vaccinated - of
course vaccination will change behaviour - for many people that's why they want to be vaccinated. It's not to be at lower risk when you visit the supermarket while you spend the rest of your week seeing noone, it's to allow you at least a bit of social contact at a lower risk.
My mum's quite close to you I think @ancientgran. She's booked into somewhere near Exeter that she says she can drive to. She's slightly uneasy about not having a letter, but I've told her she's being helpful by taking the pressure off her local GP who seems to be struggling to get through the over 75s still at present, and leaving the GP slots for those who can't drive to a larger centre.
