New coronavirus vaccination invitations are now going out nationally to millions of people aged 50 to 54 in the latest stage of the programme.

Healthcare teams continue to urge anyone yet to be vaccinated to take up the offer as around two million additional text messages go out from 17 March with a link allowing people also to pick a convenient slot at an NHS vaccine centre, or pharmacy-led service through the national booking service website.

The text alerts will be followed up with 2.4 million letters landing on doorsteps later in the week.

The NHS has already delivered a vaccine to more than 20 million people in England as supplies have flowed since early December, with the NHS committed to offering vaccinations as quickly as available supply allows in the coming weeks.

Wednesday 17 March – marks 100 days since the NHS gave Maggie Keenan her first dose of the coronavirus vaccination on December 8 2020.

NHS chief executive Sir Simon Stevens said: “Just 100 days since the NHS gave the world’s first Covid jab outside of clinical trials, our vaccine programme passes another milestone as we now invite everyone aged 50 and over to book their vaccination.”

Health Secretary Matt Hancock said: “The UK’s vaccination rollout is a national success story. It’s a tribute to everyone involved and shows what our country can achieve when we work together.

“From the Vaccines Taskforce to the NHS, our armed forces and the people coming forward in their millions to get the jab – this has been a massive national effort. I’m delighted we are now expanding the rollout and inviting those aged 50-54 to book appointments. I’m determined that no one should miss out on the chance to protect themselves and the people they love or care for, and I urge everyone who’s eligible for the vaccine to come forward.”
