In Northern Ireland, one further Covid-19 death was reported today.
The Department of Health also said that 164 new cases of the virus were confirmed in the last 24-hours.
There are 176 coronavirus patients in hospital, 18 of whom are in intensive care.
It comes as the Stormont Executive agreed a series of lockdown relaxations including a timetable for returning all schoolchildren to classes in Northern Ireland.
The relaxation focus on outdoor gatherings and sporting activities, as well as click-and-collect services for non-essential retail outlets.
Martin urges people to enjoy 'safe St Patrick's Day'
Taoiseach Micheál Martin has appealed to the public to avoid social gatherings tomorrow and to enjoy a "safe St Patrick's Day".
Speaking outside Government Buildings, Mr Martin said that tomorrow "will present opportunities for the virus to spread and that we must resist".
He said that the presence of a more transmissible and dangerous variant of Covid-19 emphasises the need for people to remain vigilant.
Mr Martin asked that people remain focussed on helping to reduce Covid-19 case numbers, adding that "very good progress" has been made since Christmas.
"It's very important that we keep the pressure on this virus and on this variant and keep the pressure off our hospitals and protect the vulnerable," he said.
Earlier, a Dublin-based GP said he was confident that doctors will be able to resume administering the AstraZeneca vaccine in Ireland by the end of the week.
Dr Ray Walley, who is also a member of the National Covid-19 GP Liaison Committee, said the target of vaccinating everyone over 70 by mid-May is still achievable because it is based on deliveries of the Pfizer-BioNTech and Moderna vaccines.
Speaking on RTÉ's Morning Ireland, Dr Walley said GPs have wholeheartedly supported the temporary suspension of the AstraZeneca roll-out, because they see it as a precautionary safety alert.
He said 11 million doses of the vaccine have been given in the UK and as a former NHS doctor, he is only too aware of the robust systems in place there to pick up difficulties.
He said that GPs in Ireland have had very few interactions from those who have received the AstraZeneca vaccine.
Dr Walley also said that GPs have engaged with the Health Service Executive to review the vaccination system and want to see a "more structured and rational" one that will not see people disappointed.
The EMA urged countries to keep using the jab after many suspended distribution despite new surges in infections.
