One-hundred military medics are to deploy to Northern Ireland to assist with the "accelerated rollout" of coronavirus vaccines.
The UK Government approved a request from Northern Ireland's Department of Health for the deployment on Friday.
Military medical personnel have previously supported frontline healthcare staff in Northern Ireland on COVID-19 wards, helping to treat the sickest patients and reduce pressures on the NI health service.
Northern Ireland Secretary Brandon Lewis said: "As we continue the mass COVID-19 vaccination rollout across the UK, I’m pleased medically-trained personnel from our Armed Forces will support health and social care teams in the delivery of this unprecedented programme across Northern Ireland."
Defence Secretary Ben Wallace said: "Today I authorised the deployment of 100 defence medics to support the vaccine rollout in Northern Ireland from the end of this month.
"Our Armed Forces are once again stepping up to support the UK’s response to the pandemic, working around the clock to protect our people in all four corners of the nation."
According to the latest data, 664,029 coronavirus vaccines have been administered in Northern Ireland - 614,629 first doses and 49,400 second doses.
More than 23 million people have now had their first dose of a vaccine across the UK.
In January, Northern Ireland’s First Minister "welcomed" assurances that further military assistance would be made available to NI if needed to help cope with COVID-19.
New estimates from the Office for National Statistics show the number of people infected with coronavirus continues to fall across England, but appears to be levelling off in Northern Ireland and Scotland.
The Armed Forces are also supporting the vaccine rollout in England, Wales and Scotland, including administering jabs.
