NHS England has invited people aged 56 to 59 to book Covid-19 vaccinations in the coming week, with letters to 850,000 people in that age bracket landing on doorsteps from Saturday and another 850,000 due to land on Monday.

“The latest invites have been sent after more than eight in 10 people aged 65 to 69 took up the offer of a jab”, the National Health Service said in an emailed statement, according to Reuters.

“NHS staff have vaccinated more than 18 million people across England, meaning more than one-third of the adult population have already received the lifesaving jab.”
