People with underlying health conditions are set to be moved up the vaccination priority list under a plan being worked on by Government this weekend.
More than 370,000 people aged between 18 and 64 were ranked at number seven in the initial vaccination allocation list announced late last year.
However, there is a strong view in Government that this needs to change given that thousands of people in this group have not left their homes in almost a year amid fears that they could get the virus.
The Minister for Health, Stephen Donnelly, has now received updated advice on the matter from the National Immunisation Advisory Committee.
