I'm 38 and definitely very pro-vax - have been eagerly waiting for my turn, especially as so many of my friends in their 30s and 40s have already had theirs.
I do have some concerns about the AZ jab though, based on the fact that if I lived elsewhere in the world the recommendation would be different. I'm actually originally from one of the countries only giving AZ to the older age groups now, and can't help thinking why should I trust the MHRA/JCVI more than the similar bodies in my native country?
Of course I understand the risk of these clots is tiny and it would be very, very likely I would be absolutely fine. I'm probably going to take the AZ jab as soon as offered.
It does feel like the 30s and 40s age groups in the UK are expected to accept the risk simply because that's the situation with vaccine supply here. It isn't purely a scientific/medical recommendation in that sense - it's not any safer to get the AZ jab here than it is in Finland, Canada or France. If there were millions of doses of Pfizer or Moderna ready and only a few doses of AZ, then I have no doubt the recommendation here would be different.
But it is what it is and at least we are lucky in the UK to have such a good vaccination programme. I wouldn't want to live in Brazil, Mexico or India right now...
