General description

This data has been published to provide a weekly summary of data on coronavirus (COVID-19) vaccination operations in Wales.

Figures show the cumulative number of doses allocated to Wales and the cumulative number of doses delivered, by date.

Number of doses includes Pfizer/BioNTech (12+ years), AstraZeneca, Moderna, and Pfizer/BioNTech (5-11 years) doses. Figures on doses allocated and delivered refer to one dose of vaccine. A course of vaccination is made up of a number of doses and will differ between individuals. Individuals who are severely immunosuppressed were recommended three doses from the beginning of the vaccination programme. The remainder of the eligible population were recommended two doses, with three doses recommended once the booster programme began in autumn 2021.

The data are taken from management information and are subject to change. They have not been not been subject to the same validation processes undertaken for official statistics releases.

The UK Government hold the contracts for vaccine volumes and deliveries to the whole of the UK. Wales receives a population share of all vaccines procured by the UK Government. Vaccines are allocated to health boards on the basis of the UK’s Independent Joint Committee on Vaccination and Immunisation (JCVI) priority groups’ population sizes following allocations given to Public Health Wales (PHW) and Velindre University NHS Trust.

Data collection and calculation

The data on vaccination allocation and delivery is drawn from information provided by Public Health England (PHE) and the Welsh Government. The data is collected from management information generated during the operation of the Vaccine Deployment Programme and collated centrally by Public Health England and, for the Pfizer/BioNTech vaccine, by the Welsh Government.

The total number of doses allocated refers to the number of doses that, in the case of the Oxford / AstraZeneca and Moderna vaccines have been made available by Public Health England to the Welsh Government for ordering (up to 11:55 on the day listed) or, in the case of the Pfizer/BioNtech vaccine, delivered directly from the manufacturer to Wales (up to the end of the day).

The total number of doses delivered refers to the number of doses that have either been delivered from Public Health England’s distributor to the NHS in Wales or, in the case of the Pfizer/BioNtech vaccine, delivered from the Welsh Government’s distributor to the NHS in Wales, and is the cumulative amount delivered by 23:59 the day before.

The difference between vaccine allocated to Wales and vaccine delivered in Wales is made up of vaccines allocated but not yet delivered.

Statistical quality

Prior to 26 January 2021 the product information for the Pfizer vaccine stated that each vial contains 5 doses; however in some cases it may be possible to withdraw a further sixth dose from some vials. The use of this additional dose is supported by the Medicines & Healthcare products Regulatory Agency (MHRA). From 26 January 2021, the MHRA updated their regulations to state that Pfizer vials officially contain 6 doses. The number of doses of Pfizer vaccine has been calculated on the basis of the date on which vaccine was received in Wales.

The product information for the Oxford / AstraZeneca vaccine states that vials contain 8 or 10 doses (depending on the presentation), however in some cases it may be possible to withdraw a further (9th or 11th) dose from some vials. The use of this additional dose is supported by the MHRA.

There are two different presentations of the Oxford / AstraZeneca vaccine provided:
• 80 dose packs (Ten 4 ml vials with at least 8 doses per vial)
• 100 dose packs (Ten 5 ml vials with at least 10 doses per vial)

The product information for the Moderna vaccine states that 10 doses of 0.5mL can be withdrawn from each vial, which is the figure used for reporting the data presented in this release; however an additional overfill is included in each vial to ensure that 10 doses can be delivered. In some cases it may be possible to withdraw further doses from some vials. The use of this additional dose is supported by the MHRA. In the case of booster vaccination, the recommended dose of Moderna vaccine is 0.25mL. Moderna is given in both 0.5mL and 0.25mL doses and as such the number of doses in a vial will vary between 10 and 20 depending on the mix of first and second, and booster doses administered.

All data on vaccines allocated and delivered to Wales are approved by the UK Government.

On 13 September 2021, the cumulative number of doses of COVID-19 vaccine that were allocated to Wales decreased compared to previous weeks. This was due to a reallocation of vaccines initially allocated to Wales, within the wider UK vaccination programme.

As of 4 October 2021, the number of vaccines allocated to Wales includes previously deferred stock for the COVID-19 booster programme which began in Autumn 2021.
