After a faltering start to the rollout, EU countries are now surging ahead with vaccinating their populations as the UK's effort starts to splutter.
Two more EU countries have overtaken the UK in the last week in terms of the proportion of the population who is fully vaccinated.
Belgium has double-vaccinated 58.9% of its population while Spain has double-vaccinated 58.31% as of 1 August, while the UK figure is 56.66%, according to Our World in Data.
Fellow EU member Malta, which overtook the UK in January, has also now double-vaccinated a massive 86.7% of people.
While the EU as a whole is still behind the UK at 39.97%, the rate at which the bloc as a whole is administering vaccines is now faster than the UK's.
The number of people in the EU who received their second jab increased by 5% in the last week, whereas in the UK, the rate increased by 3%.
Meanwhile, Belgium by increased 8% while both Portugal and Italy saw a 7% increase.
Several countries including Greece, Finland and Hungary had already overtaken the UK in terms of the speed of their rollout.
Earlier this year, the European Commission and EU countries came under fire for missteps at the start of their vaccine rollout, lagging badly behind Israel, Britain and the US.
The EU was criticised for being slower to negotiate contracts with vaccine manufacturers, and the European executive and drug regulator faced increasing pressure for what some consider slow vaccine approvals.
After a sluggish start to their vaccine rollout, many EU nations have now picked up the pace.
The UK on the other hand had a much faster rollout, with 45.88% of the population receiving its first dose by the end of March.
But the county has recently started to experience a slowdown, with fewer young people taking up the offer of a jab compared to older generations.
Nearly eight months since the first COVID vaccine was given in the UK, more than three million 18 to 29-year-olds have yet to take up the offer of a first jab.
Vaccination rates vary across the four nations of the UK, but take-up among younger age groups remains consistently lower than the equivalent figures for older groups.
An estimated 32% of 18 to 29-year-olds in England, some 25% of 18 to 29-year-olds in Wales, about 28% of 18 to 29-year-olds in Scotland and 39% of 18 to 29-year-olds in Northern Ireland have yet to have the first jab, according to the latest official figures.
