Earlier, Professor Sam McConkey said the recent surge of COVID-19 cases in Ireland cannot be predominantly attributed to new variants of the virus.
The infectious disease specialist added that while the mutant strains are "certainly a factor" in the high numbers, data shows it is the original virus contributing to the majority of cases.
It comes as a doctor at the WHO said that Ireland and other countries around the world are paying a "high" price for gatherings at Christmas.
Dr Margaret Harris said the recent surge in cases can be attributed to "winter gatherings", with many people not heeding public health advice.
She added that there is "no conclusive evidence" as yet that the new strains of COVID-19 present in Ireland will have any significant effect with the vaccines.
Meanwhile, 1,112 new cases of COVID-19 have been recorded in Northern Ireland in the last 24 hours.
