The HSE has confirmed there's been a "significant ransomware attack" on its IT systems - and has shut down the entire network to protect them.
It's apologised for the inconvenience caused to patients and the public.
The Health Service Executive says it took the precaution of shutting down its systems to further protect them, and to allow it to assess the situation.
However, a spokesperson for the HSE in Waterford says the Covid-19 vaccination programme is not affected, both Waterford vaccination and testing centres are expected to operate as normal.
More will be known later this morning in relation to impact on services in Waterford, but unless patients are informed otherwise they should continue to attend appointments.
There is a significant ransomware attack on the HSE IT systems. We have taken the precaution of shutting down all our our IT systems in order to protect them from this attack and to allow us fully assess the situation with our own security partners.
