British Prime Minister Boris Johnson will judge this week how fast England can exit the COVID-19 lockdown after vaccinating 15 million people.

But the British Health Minister said death and hospital admission numbers were still too high.

With nearly a quarter of the UK’s population, now inoculated with the first dose of a COVID vaccine in a little over two months, Johnson is under pressure from some lawmakers and businesses to reopen the shuttered economy.

“We’ve got to watch the data,’’ Health Secretary, Matt Hancock, told Sky News.

“Everybody wants to get out of this as quickly as we safely can, and both as quickly, but also as safely, are important.’’

“The question is a judgment of how quickly and safely, how quickly we can do that safely.

“That’s the judgment that we’re making this week, looking at the data, ahead of the prime minister setting out the roadmap, on the 22nd,’’ he said.

The biggest and swiftest global vaccine rollout in history is seen as the best chance of exiting the COVID-19 pandemic, which has killed 2.4 million people, tipped the global economy into its worst peacetime slump since the Great Depression, and upended normal life for billions.

Britain has vaccinated 15.062 million people with a first dose and 537,715 with a second dose, the fastest rollout per capita of any large country.

Hancock said the British government was speaking to other countries across the world about giving British people certificates, showing they had been vaccinated so that they could travel abroad in the future to countries that require them.

“There is this international work going on because if other countries require (proof of vaccination) we want to allow Brits to be able to travel to those countries,’’ Hancock said.

“We’d want to be able to facilitate that sort of vaccine certification, but it isn’t anything we’re planning to introduce here,’’ he said.

He added that a so-called vaccine passport was not something that would be required to access services in the UK.

The UK has the world’s fifth-worst official death toll – currently 117,166 – after the U.S., Brazil, Mexico, and India.

A new COVID-19 hotel quarantine system for arrivals from 33 “red list” countries, intended to limit the spread of new variants of the virus, appears to be working smoothly a few hours after it was introduced, Hancock said.

“As of 6.30, when I got my latest update, this is working smoothly; we’ve been working with the airports and with the border force to make sure everybody knows the process,’’ Hancock told Times Radio.
