The National Immunisation Advisory Council is meeting this morning to consider what advice to issue about the use of the Johnson & Johnson Covid-19 vaccine.
The European Medicines Agency this week said the benefits of the vaccine outweigh the risks of unusual blood clotting events as a very rare side effect.
Last week, NIAC advised that an alternative vaccine manufactured by AstraZeneca should not be administered to anyone under the age of 60 in Ireland because of links to similar very rare blood clotting events.
Tánaiste Leo Varadkar said he hopes that NIAC's advice will be that people under the age of 60 can get the single-shot J&J vaccine as there are enough vaccines for the over-60s.
