The country's on track for a second Covid-19 surge, which may happen in the next few weeks.
Dr Tomas Ryan from Trinity College in Dublin is among 1,000 doctors and scientists who are calling on the government to change the current strategy from suppressing the virus to eliminating it altogether.
They want widespread use of masks in public, a government campaign on how to wear them, and faster contact tracing and testing, including at airports.
Dr. Ryan, says the country is moving ahead too quickly.
"We are on path for a second surge, and that second surge may happen in mid summer or it may happen in the autumn.
"We won't have herd immunity unless we suffer 4-7 or maybe more of these lockdowns, so that we can build up 65% infections.
"That's what we want to avoid, and we think there's a better way."
