The COVID vaccine certificate should remain in place for hospitality and large events after October 22nd, according to a leading immunologist.
The measure is due to end after that date, along with most of the remaining restrictions.
However the Tánaiste says the government couldn't rule out keeping it in place, due to the levels of unvaccinated people in hospital and ICU.
Professor of Immunology at Trinity College Dublin, Kingston Mills, believes the measure should remain:
"The evidence is fairly strong in favour of the benefits of vaccination.
"Over 70% of people in ICU haven't been vaccinated so there's a much greater risk of people who are unvaccinated getting severe disease."
