A North Wales health board is working to “ramp up” its booster programme in response to the Omicron variant.

Betsi Cadwaladr University Health Board said walk in appointments “will be limited” and updates will be delivered this week.

A health board spokesperson said: “We are continuing to do everything we can to ramp up our booster programme.

“While we work on our next steps we want you to keep to your booster appointment – if you already have one for December. Please do not rearrange it.

“At this stage walk in appointments will be limited in terms of availability and location. We will advertise these accordingly. You cannot book an appointment online. Please do not contact your GP or the health board to try and book an appointment.

"We will keep you regularly updated throughout the week. Thank you for your support and understanding.”
