Left hands never seem to know what right hands are doing - I had a text from my GP surgery asking me to book, which I duly did and received the vaccine at the nearest health centre (3 minutes walk!); then I had a text from a local hospital, where I am nominally under a consultant's care, which I was told by a nurse friend to ignore if they hadn't given me a specific appointment (which they hadn't), and then a few days later the hospital telephoned me to ask if I wanted the jab, so I explained I'd already had it under the GP, so they said they'd take my name of the list.... reminds me of when I went to the chemist in December to pick up my medication, and the pharmacist asked whether I'd had my flu jab - which, again, I'd had via the practice!

Sorry about your friend; that sucks.
