Northern Ireland's hospitality sector has voiced opposition to a suggestion that Covid-19 vaccine passports could become mandatory to enter indoor venues.
The Irish Government has introduced rules to bar anyone from dining indoors unless they can prove they have been vaccinated or have Covid immunity.
Stormont ministers are understood to be considering a similar move in an attempt to address lower vaccination rates among young people.
On Monday, 72.6% of the eligible population in Northern Ireland had been vaccinated, with lower rates among the 18-30 age groups.
