Northern Ireland is opening a number of mass vaccination centres in an attempt to give booster vaccines to as many people as possible ahead of an expected surge of the Omicron Covid-19 variant.
The biggest is located in the Titanic Quarter in Belfast where a former exhibition centre will administer jabs to 4,000 people a day.
Several other Northern Ireland health trusts are also opening similar facilities.
The Belfast one will offer walk-in and pre-booked appointments for boosters as well as first and second vaccine doses.
It will start operating next week.
From Monday, people aged 18-29 will be able to get their boosters as long as three months has elapsed from their second vaccine.
Work is continuing to extend the booster campaign with more vaccination sites being brought into operation.
The requirement for a 15 minute wait after vaccination has been suspended, with the aim of increasing the number of people who can be treated daily.
Northern Ireland now has 151 confirmed cases of the Omicron variant though the real number is believed to be much higher.
Public health officials have already warned Stormont ministers that significant interventions may be needed in the new year to limit hospitalisations and protect the health service.
Stormont Health Minister Robin Swann visited the new Belfast vaccination site today.
"The emerging data on the Omicron variant is deeply concerning and we must do all we can to protect each other and our health service," he said.
Mass vaccination centres were last used earlier in the year to deliver large numbers of first and second doses.
