Flu vaccination programme expanded this year
An expanded flu vaccination programme is set to roll out across the country this autumn.
The Department of Health has said the expansion is to protect society and the health service from any surge in Covid-19 cases occurring at the same time as a spike in flu infections.
The aim of the extended programme is to reduce the overall spread of flu in the community and reduce flu-related hospital admissions through increased vaccination in vulnerable groups, according to the Department.
The department said that all of those in at-risk groups, including healthcare workers, will be able to get the vaccination free of charge.
All children aged from 2-12 can also get the vaccination free of charge.
The vaccine will be administered to children through nasal drops rather than an injection.
Minister for Health Stephen Donnelly said: "The health service is entering a challenging winter period, in the midst of a global pandemic.
"It's important that we make every effort collectively to limit the impact on the health service over the coming months.
"The vaccine will be available from your GP or your pharmacist, and I would urge everyone to get the vaccine this winter."
The expanded seasonal vaccination programme is estimated to cost €65m.
