Chief medical officer Dr Tony Holohan added: "Currently, 2 per cent of cases are being hospitalised.
"We know that we would be experiencing many more cases and hospitalisations were it not for the great progress being made in taking up vaccination.
"We need to keep this up as we move to vaccinate the remaining, mostly younger, cohorts of our population."
Dr Holohan urged those who are now eligible to receive a vaccine, who have not yet registered for one, to do so "as soon as possible".
