Ireland is in line to get an extra 46,500 Pfizer vaccines this month.
It comes after the European Commission secured an extra 4 million doses of the vaccine.
Meanwhile the Health Minister Stephen Donnelly has said the issue with vaccines is a timing one, rather than a supply issue.
Minister Donnelly played down reports of serious shortfalls in the number of vaccines expected in the first quarter of this year.
He says the country has advanced-purchased over 18 million doses - enough to vaccinate every man, woman and child in the country twice.
He insists the issue is that people want to be vaccinated as soon as possible.
