The HSE was forced to shut down its IT system today following a cyber attack, resulting in disruption to some health services.
The incident has been described as a "significant ransomware attack", focused on accessing data stored on central servers.
Hospitals have warned of disruption to routine appointments, with the Rotunda Hospital cancelling most of its appointments for the day.
The COVID-19 vaccination programme has not been impacted and is continuing as planned.
Professor Barry O'Sullivan from the School of Computer Science at UCC and Priscilla Lynch, clinical editor of the Medical Independent, joined us to discuss this.
