We have been building a vaccination infrastructure from scratch and health boards have had to upscale over the past month.  Daily vaccination rates are increasing across Wales and, looking ahead, all health boards are preparing for significant expansion in capacity from the beginning of January, with the coming on-stream of the Oxford/AstraZeneca vaccine. The vaccine will be offered in some GP surgeries from Monday.  Health boards are also increasing capacity now that foundations have been laid – with one doubling appointments next week as a result of increased staff capacity and having made efficiencies, as staff have become more experienced in handling the vaccine.  Vaccination centres have increased from 14 to 22 and many more immunisers are also being deployed over the coming weeks, with some areas doubling capacity.
