It is likely that 90% of over 18s will be fully vaccinated by mid September.
That was the prediction of the Chair of the Vaccination Taskforce.
Professor McCraith said 87.8% of over 18s have received two doses and 91.7% of this age cohort have received one dose.
He added we are now at the “final furlong” of the vaccination programme.
The “emergency phase” of the rollout will finish at the end of September, he said.
He said it is not yet clear if the Vaccine Taskforce will have a role in any booster programme adding the European Medicines Agency has not yet given approval for the vaccines to be used as boosters.
Vaccinations continue across Donegal will a walk-in clinic operating in Letterkenny this weekend for over 12s.
Chief Executive of the HSE Paul Reid said: “The finishing line of this phase of the vaccination programme is so close now.”
In a post on Twitter, Mr Reid said: “Our focus still remains to give as many as possible protection. Walk in vaccination centres continue this weekend for aged 12s & over.”
