The vaccination uptake was praised by the vaccination minister as an estimated six in ten adults in the UK have received both doses of a Covid-19 vaccine, recent figures show.
Since vaccination began in December last year, a total of 31,740,115 second doses have now been given.
This corresponds to 60.3% of all people aged 18 and over.
Of the four nations in the United Kingdom, Wales has the highest proportion of fully vaccinated adults, with 61.6% receiving both vaccinations (1,553,091 second doses).
England is just behind with 60.4% (26,745,666 second doses), followed by Scotland with 59.0% (2,617,450) and Northern Ireland with 56.7% (823,908 second doses), reports PA.
In response to the figures released by the four UK health authorities, Vaccines Minister Nadhim Zahawi said: “Two doses of a Covid-19 vaccine are absolutely essential to ensure the greatest possible protection that vaccinations have to offer – it is extraordinary that three “Five people have now been vaccinated with both vaccinations.
“No matter where you live, where you come from, what background you have or what belief you have – if you are over 18 years old, a vaccine is available to you. I urge everyone who is entitled to get their jab and help us get back to normal. “
Health and Welfare Secretary Matt Hancock said, “As evidence continues to emerge as to how effective two doses of our vaccines are in protecting against the Delta variant, it’s great to see three out of five adults were stabbed twice on our way to get around to protect the whole country as best as possible.
“We are now so close to making sure that all of the adult populations are protected – now anyone aged 18 and over can make an appointment so make sure you sign up for your first and second doses as soon as possible.”
Recent analysis by Public Health England suggests Covid-19 vaccines are highly effective against hospitalizations of the Delta variant of the coronavirus after both doses, with the Pfizer BioNTech vaccine being 96% and the Oxford AstraZeneca vaccine being 92% are effective.
The latest figures also show that an estimated 82.5% of adults in the UK have now received a first dose of a vaccine.
Wales again leads the other nations, with 88.9% of adults estimated to have had a first stab, slightly ahead of Scotland (83.0%), England (82.2%) and Northern Ireland (79.0%).
All adults in Wales have now been offered a first dose of a vaccine, according to the Welsh government.
The Westminster government has announced that it will offer a first dose to all adults in England by July 19.
The Scottish government has announced that all adults will be booked for their first dose of vaccine by June 27th, while in Northern Ireland all adults will be able to book a first dose as of May 27th.
The UK’s total first doses reported on Wednesday – 43,448,680 – is up 299,837 from the total reported on Tuesday, but that includes 48-hour data for England, not the usual 24-hour period.
This is because no data was reported for England on Tuesday due to an IT issue affecting vaccination processing, the NHS told England.
The daily increase in second-dose vaccinations – 250,875 – also includes 48-hour data for England.
