The Government has ordered a review into whether “Covid-status certification” should be used to speed up the end of lockdown.
Mr Johnson admitted the passports were being considered when he unveiled his plan to end the lockdown in England.
Addressing MPs in the House of Commons, Mr Johnson said a review would be carried out to see if the introduction of such measures could play a role in “helping venues to open safely”.
The announcement comes after weeks of the Government ruling out introducing vaccine passports for Brits to go about their daily lives.
Earlier this month Vaccine Deployment Minister Nadhim Zahawi said it would be “discriminatory” for proof of a jab to be required before to enter shops or pubs.
Mr Zahawi said at the time the Government had “no plans” to introduce such measures.
“That’s not how we do things in the UK,” he added.
