EU ranking

According to the HSE, Ireland ranks third in the European Union for the proportion of the population with at least one dose of vaccine. Portugal is the most highly vaccinated country in the EU, with 95.6 per cent coverage, followed by France. Germany has the lowest take-up, at 77.8 per cent.
One in five Irish children (21 per cent) is at least partially vaccinated, and four out of every five young adults in the 18 to 24-year age-group (81 per cent).
The average take-up in the EU in these two age-groups is 13 per cent and 59 per cent respectively.
The proportion of at least partially vaccinated people in Ireland is higher than the EU average for all age-groups.
