So why the UK/US numbers are way ahead of EU?
The UK had a head start (due to earlier approval of the AZ vaccine, they were the second ones after the Russins and before the US), of one and a half months or so. The UK gotlucky that AZs prodution in the UK went smoother than the one in Belgium. And cirumstances are in favour of the UK, initial deliviery volumes are low accross the board, regardless of supplier, and a smaller population allows higher per capita numbers in these cases.
The main reason so, IMHO, is the UKs approach and management of the campaign. With NHS, theUK coud build upon one entitiy to run things, the UK streched the second shot and didn't hold inventory back for it. And the UK seems to have proper operational supply chain management in place.
The EU (meaning individual member states) on the other hand has a larger population, at least 27 individual entities (Germany adds 16 individual states to that), o central planning (Germany has none on the federal level and I haven't seen any on state level so far neither), no coherent strategy. Appointment managment doesn't work. The EU also screwed up supply by ordering more in january (volumes that weren't needed) which resulted in further delays. And the list goes on.
In a nut shell, the UK didnt screw with the suppliers supply chains up to end f production and has a grip on the down stream supply chain up to peoples arms. The EU screwed with suppliers and has zero plan about everything after doses are delivered to a national distribution hub.
EDIT: The EU has to coordinate 27 nations and has to avoid an EU-internal bidding war. The UK doesn't.
And after contract signature, the EU basically took a step back. The EU did tell member states that logistics will be critical, and that logistics will be up to member states to sort out. Kind of right, but also kind of lazy. Even lazier are member states that failed to sort logistics out. Especially those that were fast to blame the EU for that.
The procurement, and the procurement alone, was something the member states decided ad-hoc to pool in this particular instance, in order to avoid exactly the kind of situation between member states that we currently have with the UK.
And that has actually worked remarkably well: all the EU member states have essentially the same percent of their population vaccinated. Solidarność! They are also actually doing quite well internationally, with only the US/UK and Israel significantly better (and some Gulf states).
And of course the US/UK achieved this by not playing fair. Trump tried to buy Biontech outright, and you can bet he would have denied Germany access to the vaccine developed in Germany had he succeeded. Oxford wanted to partner with Merck, but the UK government forbade this and forced them to go with Astrazeneca instead, exactly because they could then foist UK-first contracts on them.
Coming back to the EU procurement process: there simply was no precedent for this, no EU jurisdiction, no EU body that regularly does this, and thus no expertise. Thus the contracts :-/
"The EU took a step back" is incorrect, as there simply wasn't and isn't a role for the EU here at all, even the procurement wasn't really an EU thing.

"Until a few days ago" because the US just recently agreed to send some vaccine to Canada. For the first time. Canada had been getting vaccine produced in the EU. UK is still at 0.
USA has effectively banned export. UK signed a better deal (https://www.politico.eu/article/the-key-differences-between-...), three months earlier, and as a result all AZ vaccine produced domestically in the UK is going to UK Citizens, and they are higher up the queue for AZ product manufactured in the EU. This produces the same effect as an export ban (i.e. domestic production used entirely by country), but is really just the result of competent procurement.

EU shat the bed by penny pinching. Don't paint incompetence as "humanitarian efforts"
and of course the UK did as well, as the previous poster kindly pointed out:
> This produces the same effect as an export ban
How exactly you achieve being an egotistical sociopath seems a secondary concern.
Now of course both the US and the UK were in extremely dire straits at the tine, with by far the worst outcomes. So I guess that behavior is at least somewhat understandable when you have your back against the wall. Doesn't really make it any better, though.
If you care about equitable access you should be praising the UK, and in particular Oxford, for making its vaccine available at cost, and for having dedicated supply chains already established for poorer nations.
There's still plenty to criticise, but the current framing demonstrates the egocentrism of all of the actors.
The UK: 0%
The US: 0% until a few days ago.
Whereas the UK is getting the doses it ordered, at the EU's expense, and has not actually exported any.
So.
Not exactly the same.
I think your 50% figure is also too high, though it is a high proportion, but these doses are primarily going to wealthy countries.
If the EU were asking for U.K. doses to be routed to other (particularly poorer) countries I would be sympathetic to the position, but this spat is about getting the EU doses, not about equitable access.
