There will be 19 vaccination centres in North Wales as Betsi Cadwaladr Health Board gears up for the delivery of more Covid vaccines in the New Year.

The region’s Rainbow Hospitals will be in Bangor, Llandudno and Deeside, ready to be called into action for the largest mass vaccination programme in the region’s history.

They will be supported by a network of local vaccination centres in: Anglesey; Caernarfon; seven more in rural Gwynedd; Denbigh; one site in rural Conwy; three sites in Rhyl and the surrounding areas and two in the Wrexham area.

The exact location of the vaccination centres has not been revealed, but it is believed that at least four will be in Dwyfor Meirionnydd.

With more doses of the Pfizer/BioNtech vaccine on the way, and with the anticipated approval of another developed by Oxford University and Astra Zeneca, health board bosses believe there will be enough supply of the Covid jab to immunise everyone that needs it. This comes after the health board had to scale back plans to immunise staff in the central and eastern board areas this week, after a lack of supply of the vaccine.

A spokesperson said: “Enough supply is expected to cover all of the priority groups over the coming months, although the delivery models continue to be refined in response to the vaccine characteristics and supply, availability of suitable locations, and staffing.

“We are seeking clarity from Welsh Government on vaccine supply, as this will determine our plans for maintaining the vaccination programme over the Christmas period.”

However, anyone who suffers anaphylactic reactions should not be given the injection.

It said: “Individuals will have a 15 minute post-vaccination observation period to ensure they are well to leave following their vaccine. The health board is ensuring all staff are trained in identifying anaphylactic reactions, and anaphylaxis kit will be available at all vaccination centres.”

Care homes staff from all six counties in North Wales should have, or should be about to have, the inoculation at Llandudno’s Rainbow Hospital, with appointments carried out Tuesday-Thursday this week (15-17 December).

Almost 2,000 doses should arrive in North Wales before Christmas with staff in the central area who treat cancer patients, as well as those with immune deficiencies, next in line to receive the jab – followed by emergency department staff.

The health board will contact people in line for the jab and has asked that no one calls up GP surgeries or the health board asking for an appointment.
