A travel expert said he does not believe children will have to be vaccinated to go on foreign holidays later this summer.
It comes as the European Union reveals plans to ease restrictions on non-member states.
While those within the EU would use a digital green certificate to travel, which would include proof of vaccination.
Editor of Air & Travel Magazine, Eoghan Corry, told Newstalk Breakfast he does not think this will apply to children.
"It's very unlikely that young people will be vaccinated across Europe by the time we're talking about getting this up and running.
"The focus of the entire discussion has been on getting a sufficient number of vulnerable people vaccinated, and also percentages of the overall population vaccinated.
"What we're also looking at is the management of that data: passengers have a lot of documentation to manage already.
"So a lot of the discussion has actually been in the logistics of managing the data, while brushing aside the big question of: 'If the parents are vaccinated, and the children are not will they be able to travel?'
"The understanding.... is that once we have a certain cohort of the population vaccinated, that the proof of that vaccination will enable people to fly and the technology's in place to deliver that."
He said while he 'expects' Irish families will be heading off to the sun, this is up to Dublin not Brussels.
"That is not a European decision, that is going to be made probably next week by the Cabinet when and how we're going to re-open international travel.
"The state of that debate has been that we tend to run three or four weeks behind the rest of Europe.
"What will probably happen is we will watch other countries open up - look at the consequences, look at the numbers, look at the effects on COVID rates in community transmission - and then move.
"I would expect it's unlikely that we'll move before the end of July.
"What needs to happen next is the Government to work out do we return to international travel and at what pace".
It comes as Taoiseach Micheál Martin said the Government will engage with airlines to 'reboot' the aviation sector, which he said was 'crucial'.
The Government's plans for the re-opening of aviation will be revealed next week.
While earlier Tánaiste Leo Varadkar suggested it would be August at the earliest before international travel resumed.
The EU's digital green certificate system may be ready by June, but Ireland will take some time to fully sign up to it.
Under the plans, member states should allow travel into the bloc of people who have received, at least 14 days before arrival, the last recommended dose of a vaccine recognised by the EU.
Travellers should be able to prove their vaccination status with the green cert issued by member states on an individual basis.
While states should also be able to accept certificates from non-EU countries based on national law.
The plan covers all EU countries and Schengen member states including Iceland, Liechtenstein, Norway and Switzerland.
However Ireland is not included in the plans, as it is outside the Schengen area, but can be if the Government decides to align.
