It comes as infectious diseases expert Professor Sam McConkey warned that Ireland is in an "unstable" place with COVID-19.
"We know when we opened up at the beginning of December, when we did a lot of socialising and we did some inter-generational gatherings, that was when numbers skyrocketed after just about three weeks of socialising," he told Newstalk Breakfast.
"So this is an unstable place, where we're at now is not a stable place to open up and do things."
Professor McConkey added that what will help move Ireland into a better place with coronavirus will be getting the majority of the population vaccinated and investing in public health here, such as identifying and managing outbreaks in the community.
