Mullingar's Kingston Mills says the booster roll-out is more important than ever now.
Officials say 'blind luck' led to the first case of the Omicron variant being identified in Ireland.
Genome sequencing analysis was conducted on eight samples in recent days, with one being confirmed as the Omicron strain.
Public health officials say they were fortunate to identify the case, which was in a random sample referred for lab testing.
Little is known about the Omicron variant, but it is feared it could be more transmissible than other strains.
Professor of immunology at Trinity College, Mullingar's Kingston Mills, says Ireland's booster campaign has now taken on new importance.
