LONDON — Britain’s health secretary said Sunday that authorities have decided not to require vaccine passports for entry into nightclubs and other crowded events in England, reversing course amid opposition from some of the Conservative government’s supporters in Parliament.

Sajid Javid said the government has shelved the idea of vaccine passports for now but could reconsider the decision if COVID-19 cases rise exponentially once again.

“We’ve looked at it properly and whilst we should keep it in reserve as a potential option, I’m pleased to say that we will not be going ahead with plans for vaccine passports,’’ Javid told the BBC.

The U-turn came just days after the government’s vaccines minister and the culture secretary suggested that vaccine passports would still be necessary, despite growing opposition from lawmakers. Such passports are required in other European countries, like France.

In particular, members of the governing Conservative Party have objected to such passports as an unacceptable burden on businesses and an infringement on residents’ human rights.
