In Johnson's press conference just now they said the number of vaccinations was entirely limited by the available supply, not the ability to administer it, nor the distribution of it. They were explicit about this.
“Where we stand today is we have four million doses available right now and we've got enough active that we think we will be able to make a further 15 million available to the UK by the end of this year. Subject to regulatory approval, it could actually be 19 million doses by the end of this year (to the UK)."
That seems like something has clearly gone wrong, if more than a month ago they were in that position and now we are so limited by available dosage.
