They'll be administered in pharmacies, including around 30 in Kildare.
36,00 Johnson and Johnson vaccines are due to arrive here later this week, according to the HSE.
It comes as pharmacies, including 30 in Kildare taking part in the programme, have almost run out of these Covid jabs, after the rollout was extended to under-35s earlier this month.
They've administered nearly 150,000 so far - with 50,000 in the past week alone.
