As we've managed to vaccinate so many in such a wonderfully short time, I bet it wouldn't be impossible to get all the teachers vaccinated in these two weeks before schools re-open.
As for the group 6 vulnerable, my daughter-in-law has CAH (adrenal hyperplasia) and was vaccinated last week. She is 43. My daughter who lives with her got a surprise call from the surgery the day before and was told she might as well come along too and have hers, so she did. She is only 40 (couple of health issues but nothing terrible) I reckon it depends where you live. They are in the depths of Cornwall so maybe if the practice has more than enough vaccine to cover their older patients, they can cover more groups more quickly. Like rosie1959 I'd love to see my diabetic grand-daughter vaccinated too but as she's only 12 she's probably still a way down the list.
