As I said above these figures do not account for the start up money the UK government gave to AZ by means of an advance upfront payment for the vaccines we had bought.
This is where the government have played it well in my opinion. In june they bought 100000000 doses of the vaccination from AZ, as part of this they provided a large advance payment of a few hundred million. This then enabled AZ to pay to set up the infostructure needed to produce and deliver the vaccinations required. In exchange for this upfront cash the UK government wanted production sites in the UK to be established, this in turn then meant that any vaccinations produced in the UK were prioritised for use by the UK government.
It is this deal and because of this upfront money our supplies weren't affected at the start of the year when AZ's european production site had problems with filtering which meant the yield they produced was significantly down, that impacted everybody but us as we only received vaccines which were produced in UK production sites.
The current high levels of supply that the UK has is very much down to government strategy, now the delivery of those vaccines I can accept is down to the NHS but if they don't have the supplies we don't have the vaccination programme we do now.
There are loads of good articles which highlight all of this, probably better than I have but its all there if you want to look. Even the guardian have wrote an extensive article on it and highlighting how the UK government have got it right.
Or you can just say the tories haven't got a single thing right and crack on. It undermines your argument somewhat, similarly to anybody who thinks they've done a good job and got nothing wrong. You can still think they're a sham while admitting they've got something right.
