Young adults were on Friday warned that they will be grounded in Britain if they do not get the Covid-19 jab.
Transport Secretary Grant Shapps stressed that people who do not get inoculated will be unable to fly to most, if not all, countries.
He highlighted Britain’s world-leading vaccine roll-out, which has so far seen nearly 90 per cent of adults get the first jab and more than 70 per cent fully jabbed.
But he told Sky News: “Within the 20 and 30-year-olds, it’s fewer. That’s partly, of course, because they have been offered it more recently.
“But they will need to get vaccinated if they want to travel internationally again.”
In his round of morning interviews he went on to say on LBC Radio: “If you want to travel internationally, you will need to be double-vaccinated almost everywhere in the world.”
Mr Shapps added: “It makes perfect sense to get a vaccination, why would you not want to not only protect yourself but your loved ones and people that you don’t even know who will get protected when we are all protected?”
