The EU is exercising its option to buy an additional 100 million doses of the Pfizer Covid vaccine.
All doses are expected to be delivered this year.
So that would mean an extra 1 million doses for Ireland in 2021.
The total number of vaccines administered here passed 1.2 million on Saturday.
Meanwhile, the European Medicines Agency is expected to announce new advice on the Johnson and Johnson vaccine later this week.
That's after it paused deliveries in the EU and US officials paused the rollout there.
Professor of Biochemistry Luke O'Neill says he expects it to be given the go ahead:
"The guideline will probably be over 30s," he says adding, "it's a moving thing isn't it?"
While we wait for the decisions from the US FDA and the EMA in Europe, he says "it's settling at that level."
Professor O'Neill says people over 30 still have a "reasonable risk" of getting the disease.
However he says it's a, "very safe," vaccine, and believes it'll be back soon.
