Co Monaghan has the lowest uptake rate of the covid-19 vaccine nationwide.
Latest figures from the Health Protection Surveillance Centre reveals that 76.8% of people aged 5 and upwards fully vaccinated in the county.
That's only slightly above Co Donegal, and the two counties have consistently lagged behind other counties in terms of vaccine rates.
Monaghan and Donegal are the only counties to have vaccine uptake rates of less than 79% among people aged 5 and up.
The uptake rate among those aged five and up in Co Monaghan is 76.8%, slightly below Donegal on 76.9%, while 87.9% of people over 18 have been vaccinated in Monaghan.
The figures are accurate as of the 20th of March, and defines fully vaccinated persons as those who have received two doses of a two dose schedule, or one dose of a one dose schedule.
In Co Cavan, 82.1% of people over the age of 5 are fully vaccinated, and that figure is 93.3% for those aged 18 and over Cavan.
Meanwhile, Waterford continues to have the highest uptake rate nationwide, with 91.9% of people aged over 5 fully vaccinated in the county.
Nationwide, 95.1% of those over the age of 18 have been fully vaccinated, while 20.5% of 5-11 year olds are fully vaccinated.
However, registration for the youngest age-group, those aged between 5 and 11, opened in early January and Dr Denis McCauley, from Irish Medical Organisation, says the take-up among this age group isn't disappointing.
