People aged between 65-69 years can register to get their Covid-19 vaccine from April 19th and will begin to receive their jabs from that week, the HSE has said.
Taoiseach Micheál Martin has said the national portal for the general public will go live in two weeks.
HSE boss Paul Reid said once those aged between 65-69 register, they will receive a text confirming what centre they will go to for vaccination.
He said these vaccinations will primarily be carried out at one of the vaccination centres.
Mr Reid said there will be some public communications released in advance of the portal going live to explain how the system will work.
Mr Reid said from that same week, those aged between 65-69 will also start to be inoculated.
Taoiseach Micheál Martin has said close to four million vaccines are due to arrive into the country between now and the end of June.
Mr Martin said 930,000 doses would come into the country this month, with 1.2 million expected in May and 1.7 million in June.
Mr Martin defended the roll out of the vaccination programme and said there was a lot of negativity around the process when in reality he said people on the ground were very positive about the roll-out.
Mr Martin said: “The supply in April as per all of the companies and their indications to us - about 930,000 in April.
“1.2 million in relation to May, and about 1.7 plus million in June - so you’re looking at close to four million is what’s being indicated by the companies that will be supplied into Ireland in the second quarter.”
