LONDON, United Kingdom (AP) — The British Government declared yesterday that every adult in the country should get a first novel coronavirus vaccine shot by July 31, at least a month earlier than its previous target, as it prepares to set out a “cautious” plan to ease the UK’s lockdown.

The previous aim was for all adults to get a jab by September. The new target also calls for everyone 50 and over and those with an underlying health condition to get their first of two vaccine shots by April 15, rather than the previous date of May 1.

The makers of the two vaccines that Britain is using, Pfizer and AstraZeneca, have both experienced supply problems in Europe. But UK Health Secretary Matt Hancock said yesterday that “we now think that we have the supplies” to speed up the vaccination campaign.

The early success of Britain’s vaccination effort is welcome good news for a country that has had more than 120,000 coronavirus deaths, the highest toll in Europe. More than 17.5 million people, a third of UK adults, have had at lease one vaccine shot since inoculations began on December 8.

Britain is delaying giving second vaccine doses until 12 weeks after the first, rather than three to four weeks, in order to give more people partial protection quickly. The approach has been criticised in some countries — and by Pfizer, which says it does not have any data to support the interval — but it is backed by the UK Government’s scientific advisers.

News of the new vaccine targets came as Prime Minister Boris Johnson met yesterday with senior ministers to finalise a “road map” out of the national lockdown. He plans to announce details in Parliament today.

Faced with a dominant virus variant that scientists say is both more transmissible and more deadly than the original virus, Britain has spent much of the winter under a tight lockdown. Bars, restaurants, gyms, schools, hair salons and all non-essential shops have been closed; grocery stores, pharmacies and takeout food venues are still open.

The Government has stressed that economic and social reopenings will be slow and cautious, with non-essential shopping or outdoor socialising unlikely before April. Many children will go back to school on March 8 and nursing home residents will be able to have one visitor from the same date.

Johnson’s Conservative Government has been accused of reopening the country too quickly after the first lockdown in the spring. The number of new confirmed cases, hospitalisations and deaths are all declining in February but remain high, and Johnson says his reopening road map will follow “data, not dates”.

But he is under pressure from some Conservative lawmakers, who argue that restrictions should be lifted quickly to revive an economy that has been hammered by three lockdowns in the last year.

John Edmunds, a member of the Government’s scientific advisory group, said British hospitals are still treating almost 20,000 coronavirus patients, half the January peak but almost as much as the height of the first surge last spring.

“If we eased off very rapidly now, we would get another surge in hospitalisations” and deaths, he told the BBC.

Edmunds said there is added uncertainty because of new virus variants, including one identified in South Africa that may be more resistant to current vaccines.

Hancock told Sky News that the Government would take a “cautious but irreversible approach” to reopening the economy.

Despite the success of Europe’s fastest vaccination campaign, the UK Government has been accused of failing to protect disabled people, who are among the most at-risk from coronavirus.

The Office for National Statistics has found that 60 per cent of people who died with coronavirus in England in 2020 had a physical or mental disability. But many disabled people, apart from those with “severe or profound” learning disabilities, have not been put in a priority group for vaccination.

Jo Whiley, a well-known BBC radio DJ, yesterday highlighted the plight of her 53-year-old sister Frances, who has a learning disability. Whiley said her sister contracted the coronavirus in an outbreak at her care home, whose residents had not been vaccinated.

Whiley said her sister had finally been offered a shot of vaccine — but it came too late.

“She was actually called in for her vaccine last night. My mum got a message to say that she could get vaccinated, but it’s too late, she’s fighting for her life” in the hospital, Whiley told the BBC. “It couldn’t be crueller.”
