The European Commission has recommended all member states suspend flights from countries in southern Africa.
It's in response to the emergence of a new variant which could be more transmissible than the Delta variant.
Commission President Ursula von der Leyen says the vaccine contracts with pharma companies say their jabs must be adapted to the emergence of new variants.
Speaking this afternoon, she outlines that flights should be suspended until more is known about the new strain.
Meanwhile everyone over the age of 16 has been given the green light for a Covid booster vaccine.
It comes after a recommendation from NIAC, which has been accepted by Health Minister Stephen Donnelly.
Over 666,000 boosters or third doses have been given out so far, to over-60s, healthcare workers and those with compromised immune systems.
