However, Steve Brine, a former health minister, branded the process “cumbersome” and called on the Government to “urgently find a way” for teenagers to be treated with “fairness and parity” when seeking to travel abroad.

The Prime Minister has also stressed that “ease of travel” should be one of the benefits of receiving the coronavirus vaccine.

A Government source stressed the relaxations were not “formally decided” and had yet to pass through Covid-O on Monday, but were strongly expected to be approved.

“It’s been difficult for some teens to go abroad because they can’t prove they’ve been jabbed or had a test. Making Covid passes accessible for them will make family holidays a bit easier,” the source said.

The Telegraph revealed last week that families had been forced to cancel holidays next month due to the “restrictive” vaccine passport demands.

Parents made the decision to pull out of, or postpone, overseas trips after spending weeks trying – without success – to secure proof of their children’s vaccination status or confirmation that they have recently recovered from Covid.

A “digital solution” to the problem was initially meant to be rolled out for under-16s at the beginning of this year. Boris Johnson hinted last week that Sajid Javid, the Health  Secretary, would be making a statement about it “in the next few days”.
