NPHET will meet later to consider new guidance on nursing home visits and if there can be a 'vaccine bonus' for residents in the coming months.
Any measures will likely form part of new recommendations to government ahead of the expected easing of restrictions in April.
It comes as a further 631 new Covid-19 cases have been reported, along with 47 deaths.
Consultant in infectious diseases, Dr Eoghan De Barra, says having slightly different rules for those who are vaccinated is a good idea.
"I think there has to be some kind of carrot for the vaccinated people.
"The US is saying that vaccinated people can meet together, the UK is introducing limited visitation for people in nursing homes.
"The vaccines really do work, so I think there's going to have to be an approach that allows that balance of people's visitation, their mental health, in parallel with close watch on what happens."
