The Johnson & Johnson vaccine could be approved for use in the next two months.
Tánaiste Leo Varadkar expects the first doses of the Johnson & Johnson Covid-19 vaccine to be administered here in April.
The company says its jab is 100 per cent effective at preventing hospitalisations and deaths, and 66 per cent effective overall.
Leo Varadkar says he expects the vaccine to be approved in the next two months.
Meanwhile, the country's vaccine advisory group is meeting this weekend.
They're to recommend how the AstraZeneca Covid vaccine should be used.
The AstraZeneca vaccine was approved yesterday - and will be available here in about ten days' time.
The jab's been approved by the European Medicines Agency and the first doses will start arriving here in the second week of February.
The regulator said information for the vaccine's effectiveness in over 55s was limited - but it does expect a level of protection.
Kingston Mills, a professor of immunology at Trinity College Dublin, says prioritising other vaccines- such as Pfizer/BioNTech- for that age group could be considered.
