The Dáil last night heard calls for Britain to be added to Ireland's mandatory hotel quarantine list.
Almost all restrictions will be lifted in England on July 19th - which the British government says could lead to 100,000 cases a day.
Independent TD Joan Collins says that poses a big threat to Ireland.
"My concern is that with Delta running rampant in the UK, it could become a variant factory. We could have mutations develop as Delta runs through the population, and we have to protect our vaccine programme here.
"I think there needs to be a serious discussion with NPHET and the HSE about whether mandatory hotel quarantine is put in place."
