MORE than 15 million people in the UK have now had their first dose of a Covid-19 vaccine.

The Prime Minister confirmed the milestone and described it as an 'extraordinary feat' to have vaccinated millions of the most vulnerable people in the country.

Boris Johnson also said that in England, jabs have been offered to everyone in the Government’s top four priority groups.

The priority list set out by the Joint Committee on Vaccination and Immunisation (JCVI) includes nine categories.

At the top was care home residents and their carers, followed by people over the age of 80 and frontline health and social care workers.

The third priority group was people aged 75 and over, and the fourth group was people over the age of 70 and those deemed to be 'clinically extremely vulnerable'.

In a video posted on Twitter, Mr Johnson said: "We have reached a significant milestone in the United Kingdom’s national vaccination programme.

"On December 8 just after 6.30am in the morning, this country’s first coronavirus jab was delivered safely into the arms of Margaret Keenan at University Hospital in Coventry.

"In the following two months, this country has achieved an extraordinary feat, administering a total of 15 million jabs into the arms of some of the most vulnerable people in the country.

"Those vaccines have been delivered in our NHS hospitals, in GP surgeries, in high street pharmacies, in cathedrals, churches, mosques and temples, in community centres, in living rooms, in cities, towns and villages across England, Scotland, Wales and Northern Ireland.

"We’ve even delivered jabs in a fairground."

He said it has been a 'truly national UK-wide effort', adding: "We’ve done it together."
