He said the vaccination rollout programme is still on track.
Taoiseach Micheál Martin has confirmed that 80% of adults will be offered their first Covid-19 vaccine by June.
Martin recommitted to the target following a cabinet meeting on the recalibration of the vaccine rollout programme on Wednesday.
Speaking on the RTE News, the Taoiseach said that four in every five adults who want to be vaccinated will receive an offer for their first dose in the coming months.
"There will be bumps along the way, but the key point is that our programme is agile and is responsive and we're very determined to go at this as effectively as we can," he added.
"Again, we received this morning clear assurances from the HSE that 95% of what we have, we will get out there on a weekly basis."
In a statement released after the
cabinet meeting, the Government said it is currently "recalibrating" its approach after recent developments.
The Government said the immediate focus of the vaccine plan is on those over 60 and people in high-risk categories.
They said that people aged 59 and under in very high-risk and high-risk categories who have yet to be vaccinated will receive an alternative vaccine to the AstraZeneca vaccine.
The statement read: "The programme is agile and responsive to any EU or global changes and this supports rapid reaction to developments in relation to the vaccine.
"Even with the advice on AstraZeneca and the pausing of Janssen, the programme is well underway."
It comes as Ireland is set to receive 550,000 more
Pfizer-BioNTech vaccine doses over the next three months than originally expected.
The producer has reached a deal with the European Commission which will see countries in the European Union receive 50 million more Covid-19 vaccines in the second quarter, the head of the EU commission said on Wednesday.
Ursula von der Leyen said the deliveries will likely start this month and will take total supplies to the EU from Pfizer to 250 million doses in the second quarter of this year.
