A former state epidemiologist for Sweden has claimed Ireland's coronavirus lockdown is pushing the serious cases into the future.
Dr Johan Giesecke has also claimed the Irish approach is "destroying the fabric" of our society and economy.
Sweden has never gone into full lockdown - instead opting for a 'soft' approach.
They are keeping shops and restaurants open, and relying on people limiting their contact with other people.
Over 3,500 people have died there, but the hope is most of the population would be immune if there is a second wave.
Dr Giesecke, who is advising the Swedish government on its approach, told Newstalk Breakfast it is a better approach than the path Ireland is taking.
"One example is your neighbour the United Kingdom: they have more deaths per million inhabitants than Sweden has.
"And they've had a rather severe lockdown all the time, that's one example".
"The other is that what you do is you push your cases into the future - many people will get infected once you open the lockdown".
"But you can't keep a lockdown in Ireland for a year, that would be impossible."
He said he believes ultimately everyone will get the virus: "That's true for all respiratory tract infections like this - influenza, measles - you can't get rid of them without a vaccine.
"If a good vaccine comes along, then I'm wrong - but if not, everyone will get it in the end".
"I don't think that the serial lock-up is a very good solution.
"You're destroying the fabric of your society and your economy - and you [are] pushing the serious cases into the future."
He added that while he agrees on flattening the curve through a lockdown, "they will not prevent people from coming infected in the future".
