All adults in England should be able to book a Covid-19 vaccination jab “by the end of this week”, the NHS chief has said.

Sir Simon Stevens, chief executive of the NHS in England, told the NHS Confederation annual conference that the NHS would “finish the job” of the Covid-19 vaccination programme to the “greatest extent possible” over the next four weeks.

He said: “It is now very important that we use the next four weeks to finish the job to the greatest extent possible for the Covid vaccination programme, which has been a historic signature achievement in terms of the effectiveness of delivering by the NHS – over 60 million doses now administered.

“By July 19 we aim to have offered perhaps two thirds of adults across the country double jabs.

“And we’re making great strides also in extending the offer to all adults – today people aged 23 and 24 are able to vaccinate through the National Booking Service.

“I expect that by the end of this week, we’ll be able to open up the National Booking Service to all adults age 18 and above.

“Of course, vaccine supply continues to be constrained, so we’re pacing ourselves at precisely the rate of which we’re getting that extra vaccine supply between now and July 19.”

He also revealed that just 1% of hospital beds in England are occupied by patients with Covid-19.

He said:  “At the moment about 1% of hospital beds in England are occupied by patients with a Covid diagnosis and the age distribution has really flipped as a result of vaccination.

“Back in January, it was 60/40 – 60% of beds occupied by people over 65, 40% (occupied by people) under 65.

“Now it’s flipped to 30/70, so it’s about 30% occupied by people aged 65 and over 70% by younger people whose prospects are much greater.”
