The Tánaiste Leo Varadkar says the country will be proceeding with a further easing of COVID-19 restrictions on Monday.
It comes as the country's five-day moving average of cases has dropped by nearly 15% in the past week.
It now stands at 1,526, compared to 1,791 seven days ago.
While 1,414 new cases were confirmed here on Friday.
Mr Varadkar says the vaccination of those under-35 is 'really working now'.
In a tweet, he adds: "Cases have plateaued/falling. Rise in patients in hospital and ICU slowing.
"All OK for next stage of re-opening on Monday".

From Monday, organised indoor events and mass gatherings can take place with up to 60% of a venue's capacity, where all patrons are either fully vaccinated - or have recovered from COVID-19 in the previous six months.
While cinemas and theatres will also have capacity limits of 60%.
For indoor music, entertainment or sporting events, the audience should be fully seated.
However where patrons have mixed immunity status, there will be no change to the current limits during September.
Organised outdoor events and mass gatherings can take place with capacity limits of 75% of venue capacity.
And all religious ceremonies can proceed with 50% of venue capacity, regardless of immunity status of attendees.
It comes just days after public transport services began operating at 100% capacity for the first time in 18 months.
Masks are set to remain mandatory on public transport beyond October 22nd and the easing of most remaining restrictions.
But the return to full capacity meant the now-familiar yellow signs blocking off seats have been removed.
