Most Britons think you should be barred from the pub if you can't prove you've had a vaccine

Drinkers should not be allowed in pubs if they can't prove they've had a COVID-19 vaccine, according to a majority of Britons.

More than half also believe you should need a vaccine passport to go to care homes, gyms and cinemas, YouGov polling has found.

In February, Boris Johnson insisted he was not planning on introducing the concept.

Health secretary Matt Hancock has said some form of proof will be necessary but chancellor Rishi Sunak has warned there are "practical, legal and ethical issues" surrounding potential vaccine passports.

YouGov's polling, carried out in February, found that Britons also back passports for entry to restaurants and beauty salons.

Less than half supported using them to go to hairdressers, coffee shops and large shopping centres, and 45% felt they should be needed for public transport.

Just 33% believed they should be available for pub gardens, even while a majority backed them for going into pubs.

Research commissioned by London City Airport suggests 75% of people would be willing to carry proof of vaccination if it allows them to travel.

Hancock has told MPs "it is clear" some form of proof will be needed, and the European Union is planning for anyone who travels to the bloc to prove vaccination or provide a negative COVID test.

Former prime minister Tony Blair has said people may not have confidence to return to normal life without vaccine passports.

But Johnson said last month: "What I don’t think we will have in this country is – as it were – vaccination passports to allow you to go to, say, the pub or something like that."

Sunak told Good Morning Britain on 4 March: "There are some obvious challenges – some people are not able to, for health reasons, to get vaccinations.

"And then there is the practical aspect – how do we verify it, what kind of technology would one use, what circumstances would it be appropriate to use it?

"It is too early to say anyone is minded to do anything – that is quite a specific phrase – but I think it is right we go through all of that to surface what some of the issues and benefits might be, and then we can decide and make a decision in the round in the coming months."

In the UK, more than 22 million people have had the first dose of a vaccine, while just over a million have also received a second dose.
