On Wednesday, health minister Robin Swann said that the rollout would be extended to 18 to 24-year-olds “in the very near future”.
And on Thursday he said: “I am delighted that our vaccination programme is now open to all adults in Northern Ireland. I know this will be very welcome news for young people who have been waiting patiently for their turn to get the jab.
“Today’s announcement is another important milestone in the drive to get as many people vaccinated as quickly as we can, so that we can see a return to normality.
“The tremendous success of the vaccination programme has brought great hope and has helped to enable the recent further easing of restrictions.
“The expansion of the vaccination programme, well ahead of schedule, to everyone aged 18 and over is testament to the hard work and dedication of all those involved in delivering the vaccine throughout Northern Ireland.”
People aged 18 and over will be able to book their jabs from 8am, the Department of Health added.
