As far as I can understand it, it’s Italy refusing to send the vaccines. Italy has stated that Australia is not a vulnerable country, there is a shortage of vaccines in the EU still and it’s a high dosage that they requested. It seems quite reasonable. It’s certainly a far more coherent rationale than anything Trump would have come up with.
There are plenty of countries around the world that are far more vulnerable than anywhere in the EU. I don't see vaccines being shared with them either, leastways in the amounts required, so this is just hypocrisy.
It's particularly egregious, because the EU has stockpiles of unused Astrazeneca vaccine, due in part to its own leaders throwing shade on that vaccine.
