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 number of doses not suitable for use, as a percentage of doses administered plus doses unsuitable for use.

Vaccines unsuitable for use include doses that fail quality assurance on initial inspection, doses that fail quality assurance following preparation and vials/doses which expire during the vaccination session. This is based on information reported in the Welsh Immunisation system (WIS). There may be additional unusable doses that have not been recorded.

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.


Data collection and calculation

Digital Health and Care Wales (DHCW) data from the Welsh Immunisation System (WIS) is used for vaccine doses not suitable for use. There may be additional unusable doses that have not been recorded.

The percentage of doses unsuitable for use is calculated using the total doses unsuitable for use and dividing this by the total doses administered and the total doses unsuitable for use.

Statistical quality

Figures shown are cumulative as at 10pm Thursday each week until 4 March 2021; from 14 March 2021 onwards the figures are cumulative as at 10pm on the Sunday of each week.

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.

During the week to 5 September 2021, there was an increase in the percentage of vaccine doses reported as not suitable for use in Wales. This was mainly driven by AstraZeneca vaccine batches reaching expiry dates during August 2021, accounting for approximately 40,000 doses.

Between 19 September 2021 and 24 October 2021, three dose primary courses and booster doses were included in the number of doses unsuitable for use but were not included in the number of doses administered. This may have had a small impact on the percentage of doses not suitable for use.

From 24 October 2021, the cumulative number of doses administered includes three dose primary courses and booster doses. At the time of implementation, Oxford/AstraZeneca and Moderna doses were used in small quantities for three dose primary courses and booster doses and so this change had little impact on the percentage reported as not suitable for use. However, the percentage of Pfizer BioNTech doses reported as not suitable for use saw a slight decrease.

As at 23 January 2022, the cumulative number of Pfizer BioNTech doses administered includes Pfizer/BioNTech (12+ years) and Pfizer/BioNTech (5-11 years) doses, while the number of doses ‘not suitable for use’ is based only on doses for 12+ years. At the time of implementation, doses for 5-11 years have been used in very small quantities, meaning there is little impact on the overall percentage reported as ‘not suitable for use’.
