Meanwhile, Taoiseach Micheál Martin has said he is disappointed "with some of the issues" with vaccine supply in the first three months of this year.
It follows reports this morning of a significant shortfall in the expected supply of vaccines to Ireland by the end of March.
Elsewhere, Johnson & Johnson has told the European Union it is facing supply issues that may complicate plans to deliver 55 million doses of its Covid-19 vaccine to the bloc in the second quarter of the year, an EU official told Reuters.
Any delay would be a further blow to EU's vaccination plans, which have been hampered by bumpy supplies from other vaccine makers and a slow roll-out of shots in many member states.
In Northern Ireland, the Health Minister said the vaccination roll-out is likely to be significantly ramped up with one of the largest deliveries of the AstraZeneca jab to Northern Ireland expected this week.
Speaking during a visit to a vaccination centre at the Ulster Hospital in Dundonald, Robin Swann said some of the regional vaccination centres are being moved from Pfizer to AstraZeneca due to the imminent delivery.
