Around 10% of eligible people in eight counties remain unvaccinated against Covid-19.
New HSE figures show Donegal has one of the lowest uptake rates with 81.3% of over 12s vaccinated.
However, people availing of the vaccination programme in Northern Ireland may account for a portion of those who did not receive a vaccine in Donegal.
Figures up to the start of last week show Waterford has the highest uptake rate with 96.6% of over 12s fully vaccinated followed by Wexford and Carlow.
