Public health officials are reminding people to keep their distance if they’re meeting outdoors.
From today, two households can meet outside for social reasons but not in their gardens.
People can also travel anywhere within their own county or 20km from their home.
Professor of health systems at DCU Anthony Staines has offered advice to people on how to keep safe.
He said: “Be careful, stay outdoors, that's really the message. When you get offered vaccination, take it up. Vaccination is a huge part of this. Whatever happens with viral strains circulating, vaccination is going to be extremely important.”
Meanwhile, further changes to the vaccine rollout plan are expected as health officials meet this afternoon.
It is expected the National Immunisation Advisory Committee (Niac) will recommend AstraZeneca be used only for over-60s amid concerns about rare blood clots.
That would require significant changes to the existing age based plan.
However, just one in five vaccines due to arrive into the country over the next three months are from AstraZeneca.
Immunologist and professor at Trinity College Luke O'Neill says Ireland would be following the example of other countries.
Prof O'Neill said: “Well some countries are suspending it entirely, as you've seen, especially in the under-55s. France and Germany have said if you have had one shot of AstraZeneca get a different shot of a second vaccine so all these guidelines are changing which is a bit disconcerting for people, especially when we know the problems are extremely rare.”
