A further 1,015 cases of Covid-19 have been confirmed as people are being asked to keep their guard up even after vaccination.
Outbreaks are being reported around the country following incidents of symptomatic people mixing with others.
The Chief Medical Officer said public health doctors are reporting symptomatic people going to work, dining out or visiting friends.
"Please remember that you should stay at home if you have symptoms even if you are vaccinated, because you could still transmit Covid-19," said Dr Tony Holohan.
Dr Holohan said that going to work or to meet friends while displaying symptoms of Covid could be the beginning link that sets off a chain of transmission that leads to an outbreak.
Progress made in the vaccine rollout is encouraging but people must be willing to adhere to the basic safety measures if the country is to emerge from the pandemic.
The thousands of young people who queued at walk-in vaccination centres over the bank holiday weekend were commended for their resilience throughout the challenging time that has been the Covid-19 pandemic.
"It is this same spirit of solidarity, commitment to keeping our whole community safe by getting vaccinated, and keeping to the basic safe measures such as staying at home if you feel unwell that will ultimately be our pathway out of this pandemic."
According to the Department of Health, there are currently 178 Covid patients in hospital, of which 29 are in ICU.
Ireland has finalised a deal to buy 700,000 Covid-19 vaccine doses from Romania and the EU, Taoiseach Micheál Martin has said.
The plan to buy the additional doses had first been reported over a month ago.
Taoiseach Micheál Martin has now confirmed that the deal has been finalised.
Announcing the additional supply, to be used in Ireland’s ongoing National Vaccination Programme, Mr Martin said: “This is a welcome boost to our ongoing and very effective national vaccination programme.
“As deliveries arrive this month, they will be used to meet the continued high uptake of our Covid vaccines.
“I want to thank Romania and the EU for their assistance and show of solidarity to Ireland as we further protect our citizens in this pandemic.”
The Government had hoped to buy a million doses, including 700,000 Pfizer/BioNTech and 300,000 Moderna vaccines.
Both are mRNA vaccines and are approved for use in under-18s by the European Medicines Agency.
Romania has one of the lowest vaccination rates in the EU, and there had been fears vaccines would spoil by the end of this month if not used or sold on. Last month Romanian officials said moving the vaccine is a complex logistical operation.
The vaccines will be taken from the Romanian allocation, however, they will arrive directly from Pfizer's production plant in Belgium.
Meanwhile, Immunologist Professor Luke O’Neill says Ireland is on course to have the highest uptake of Covid-19 vaccines among young people in the world.
Over 30,000 people received a jab at walk in vaccination centres over the weekend.
The six millionth Covid vaccine will be administered here this week while the programme will extend soon to 12 to 15-year-olds.
The HSE says the success of the walk in centres outstripped their expectations with CEO Paul Reid saying the young people of Ireland showed up when needed.
The HSE’s National Lead for the Vaccination Programme, Damien McCallion, says they may now extend the walk-in centres as a result.
"One of the objectives of the walk-ins was to try and attract people who may not have previously engaged with the programme and were not registered," said Mr McCallion.
"We found good uptake and indicative numbers would suggest that maybe half the people were people who had not previously registered."
