DS (late 20's) is in Sydney and booked to have his AZ vaccine the day after it was offered to anyone under 40 prepared to 'take the risk'. He did his research, and was happy to do so, but the nurse at the clinic asked him why he didn't wait for 'a few weeks' for Pfizer, as he was more likely to have blood clots or die with AZ. 
He was quite cross that having made his decision, he was being told this, and she said that although she appreciate the statistics of a problem were minute, they have to tell patients.
Four weeks later, he's now being chased to have his second jab.
Many of his friends were reluctant to have the AZ jab that is now being offered, although with Delta taking off, more are coming round to the idea.
Hopefully whatever happens with the numbers in Aus and NZ, the impact won't be so massive as it was initially in Europe, as there are proven treatments that help enormously.
