Classic "dog ate my homework" type of excuse. Gladys has it all over her for courage, having had her AZ right at the start.
Of my close family (eg wife, children/spouses), 3 out of 4 have had AZ (youngest 40yo), 1 Pfizer, and 2 under 30 waiting their turn which will be Pfizer. One brother had Pfizer as on front line (Border Force) and his wife was invited to join that group and has had her Pfizer as well (both over 50). Another brother and his wife have had AZ, so overall will end up about 5 all.
I just do not understand the terror struck into the hearts of (just) over 50s about AZ given the likely impact of the Delta strain if they come into contact.
