The Health Minister Stephen Donnelly says we could see the rollout of Covid-19 vaccines start before the end of the year.
It comes as the government's published its plan for how 14.6 million doses will be administered.
From manufacturer to millions of people getting it, this plan sets out how exactly Covid-19 vaccines will be rolled out.
They'll take place initially in nursing homes and large hospitals before mass vaccination centres, which could include sports stadiums and colleges, are used for the wider rollout.
A new IT system will be used so people can pre-register for their jab while a communications campaign will see public health doctors addressing misinformation on social media.
Chief Medical Officer Dr Tony Holohan says it'll be a few months before the vaccine starts to have a positive impact.
Around 1,500 healthcare workers will be involved in vaccinating people initially - but the HSE says that'll need to be expanded when more jabs become available.
The European Medicines Agency has confirmed today that its meeting to consider approving the Pfizer vaccine has been moved forward to next Monday.
Health Minister Stephen Donnelly says it could mean doses arriving in Ireland before the new year.
All of those involved in the plan are agreed that today marks a positive step in the fight against Covid 19.
