Minister for Health Stephen Donnelly has said that community vaccination of people aged 70 and over will begin next month.
In a statement, the Health Minister said that the oldest people will be prioritised with people aged 85 and older to receive a vaccine first, followed by people aged 80-84, 75-79 and then 70-74.
"Despite anticipated disruption to deliveries, which was announced on Friday 22 January, Ireland will receive a delivery of AstraZeneca vaccine within the expected range for February, although at the lower end of that range.
"Delivery in March is likely to be more impacted and considerably lower than what was originally stated by the company," he said.
"We continue to prioritise those most vulnerable to Covid-19 in our society against the backdrop of limited supply of vaccines," Mr Donnelly continued.
This group will be the third group to be vaccinated in line with the Government’s Vaccine Allocation Strategy.
"The HSE is preparing a public information campaign that will provide all necessary details in advance and ensure that everyone knows when, where and how to access their vaccine," Mr Donnelly said.
In the meantime, he said, completing vaccinations for those most vulnerable to Covid-19 infection "remains the priority".
"Every possible nursing home resident has already received one dose and some have received second doses. "Healthcare workers are also a priority.
"Second doses will be administered over the coming weeks to 77,000 healthcare workers.
"We will continue to roll out first and second doses to our remaining frontline healthcare workers during February," he said.
"Our vaccination teams were unable to vaccinate some nursing homes residents and staff who had Covid-19 recently, or vaccinate those in some facilities where there were particularly large outbreaks.
"I would like to reassure those staff and residents that they will be prioritised and vaccinated as soon as possible, and in line with the guidelines drawn up by our National Immunisation Advisory Council," he continued.
Mr Donnelly said, as of yesterday, the HSE has administered 143,000 vaccine doses.
He thanked the HSE, members of the High-Level Task Force on Covid-19 Vaccination, and their teams, for "the effort and commitment they are putting into the efficient roll out of the vaccine programme".
"Everyone involved understands the importance of this programme to the country.
"Everything that can be done is being done, and will be done, to deliver it.
"There is huge interest in our vaccine programme, which is very welcome.
"I committed recently to providing the public with daily figures, as full transparency is important.
"The HSE has advised that there is a backlog of figures to be inputted and validated.
"It is working hard to achieve full utilisation of the vaccination IT system at which point it will be in a position to provide updates," he continued.
