Changes to the isolation rules on close contacts takes effect from midnight tonight.
It means if you're a close contact, have no symptoms and received a booster jab you will no longer need to self-isolate.
However you'll be required to take antigen tests and wear a high-grade mask.
Anyone under 40 who also tests positive on an antigen test won't need a PCR to confirm they've caught the virus.
They'll also be asked to upload their antigen test result on the HSE website, with a system expected to be up-and-running by tomorrow.
The change in rules comes as a further 20,909 cases of Covid-19 were confirmed here yesterday.
