What a great thread - I have passed on the link to my DSIS and BIL, both 44. They have now booked. Thank you!
I got called last week via the GP service - I am 41. Had AZ earlier this week (no side effects). London.
I moved last month and my old GP kicked us off their list (even though we moved less than 2 miles away) so I hastily joined a new surgery, I must have got lucky and joined at just the right time - my old neighbour (same age and at my old GP surgery) has not been called. It is so random.
