.... which vaccine had you had?
I seem to know an awful lot of people who've managed to catch Covid despite two vaccinations, but then I got thinking that most of my friends / contemporaries have had the AZ vaccine because of our age (over 40, under 70).
I don't know of many people who've caught it after vaccine in the older age group (70+) but is that because they mostly had Pfizer or because they're not of working age and still able to lie a bit low?
