It means a quarter have had both jabs – a total of 13,201,811 people.
The Health Secretary will today address the nation after reaching the huge milestone.
The success of the vaccine rollout means it is the equivalent of 25.1 per cent of the adult population being protected against severe illness or death.
Wales is estimated to have given two doses to 27.8 per cent of adults, ahead of England (24.9 per cent), Scotland (24.9 per cent) and Northern Ireland (24.5 per cent).
The figures are for vaccinations reported by the UK’s health agencies up to and including April 26.
It reflects the speedy pace at which the administering of second doses has been ramped up across the country during the past month.
Just under 2.8 million second doses were recorded in the week to April 26 – the highest number for any seven-day period so far – with nearly 8.7 million since April 1.
This compares with just under 3.7 million second doses in March and just 321,607 in February.
Second doses of Covid-19 vaccines must follow within 12 weeks of the first, meaning the millions of people who received their initial jab in February have recently had a follow-up dose, or are due to get the jab shortly.
People aged 80 and over were among the first groups on the priority list for vaccines, with initial doses offered from early December.
It comes as millions more people are eligible to get their Covid jabs.
