FOUR million Brits can book Covid boosters from Monday as the NHS kicks-off the Omicron jabs rollout.
Invites for over-75s, vulnerable people and health and care workers are in the post and online booking opens next week.
Invites for the over-50s will follow.
Virus cases are plummeting but medics fear winter will be rough as people are indoors more and immunity wears off.
The vaccines have been updated to fend off Omicron and future variants.
NHS England chief Amanda Pritchard said: “We know that this winter will be challenging, with a likely resurgence in both Covid and flu for the first time ever.
“The best way to protect yourselves and your loved ones is to get the next generation Covid vaccine as well as your annual flu jab.”
Vaccinators will visit care homes and housebound people next week to dish out the first doses.
The new Moderna vaccines, which are made to target Omicron specifically, will offer better protection and slow transmission more effectively.
Health Secretary Steve Barclay said: “An autumn booster will top up the immunity of those most vulnerable to Covid ahead of the winter, to help us continue to live with this virus without restrictions.”
