More people in their thirties will be able to get vaccinated against Covid-19 this week.

The NHS Covid vaccination programme, which is the biggest in health service history, continues its rollout by opening up to people aged 36 and 37 from tomorrow (Tuesday).

More than a million more people will be eligible for a life-saving Covid jab with due to update at 7am.

Texts inviting people to book a vaccination will be sent going to those aged 37 tomorrow (Tuesday) and to 36 year olds on Wednesday.

The texts will allow people to access the national booking service at the touch of a button and arrange an appointment at an NHS Vaccination Centre, pharmacy or GP vaccination site.

The move to the next age group comes as more than 930,000 appointments were made in the days since the NHS Covid vaccination programmes opened to 38 and 39 year olds.

More than three out of four people aged 40 to 49 – over five and a half million people – have also received a first dose of protection.

People 39 and under who are eligible, and pregnant women, will be offered the Pfizer or Moderna vaccine in line with recently updated JCVI guidance.

NHS national medical director Professor Stephen Powis said: “Bookings for the fastest and most successful NHS vaccination programme in history continue to surge with more than 930,000 appointments made in a matter of days since opening up to 38 and 39 year olds.

“With well over 30 million first doses of vital protection against coronavirus delivered just six months into the NHS vaccination drive, the NHS is able to open up to 36 and 37 year olds as the programme continues at pace.

“On the advice of the Government and JCVI people aged 50 and over and the clinically vulnerable are having their second doses brought forward to counter the spread of the Indian variant.

“Nobody needs to contact the NHS. You will be told how to rebook if you need to.

“Getting vaccinated is the most important step we can take to protect ourselves, our families and our communities against Covid-19, so when it is your turn to get your first or second dose please do so.”

The Government and the JCVI announced that second dose appointments will be brought forward from 12 to eight weeks for those aged 50 and over who have yet to received theirs.

The NHS made history when Maggie Keenan became the first person in the world to be protected against coronavirus outside of a clinical trial when she received the Pfizer vaccine at Coventry Hospital on December 8.

Since then more than 30 million people have been vaccinated with a first dose in England, two thirds of the total adult population.

More than one third of adults have had both doses, meaning they have maximum protection from the virus.

When invited, people will be able to book at one of the Vaccination Centre, pharmacy or general practice sites across the country that are available through the national booking service.

Text invitations appear as an alert from ‘NHSvaccine’, including a web link to the NHS website to reserve an appointment.

People who cannot go online can call the service on 119 instead to book their jab.
