Cystic Fibrosis campaigners have been welcoming the announcement that Orkambi will be available from next month.
The HSE and manufacturers Vertex have reached agreement in principle - it now just needs to be signed off by lawyers on both sides.
It comes as Cystic Fibrosis Ireland holds its national awareness week, which will see fundraising take place across the country tomorrow.
