This weekly statistical release includes management information on the number of vaccine doses not suitable for use in Wales and local health boards. We’re publishing this to support the commitment to keep individuals up to date about the vaccination roll out, as set out in the Vaccination Strategy for Wales.

This release does not include statistics on people vaccinated. Data on vaccinations given are published daily and weekly, on the Public Health Wales Rapid COVID-19 Surveillance Dashboard, with the weekly data providing more detailed breakdowns.

There are currently two types of vaccines being supplied and administered for coronavirus (COVID-19) in Wales, Pfizer BioNTech and Oxford AstraZeneca. The first dose of the Pfizer BioNTech vaccine was administered on 8 December 2020 and the first dose of the Oxford AstraZeneca on 4 January 2021

An accompanying table, with the data shown in this release is available separately.

In future releases we plan to include data on doses allocated to Wales as well as wastage. The UK Government has asked that vaccine stock data is not published due to current commercial sensitivities. We are working across the 4 nations to reach an agreed manner for publishing stock information and will update when we are in a position to do so.

1. Main results

As at 21 January at 5pm

0.5% of Pfizer BioNTech and 0.1% of Oxford AstraZeneca vaccine doses delivered to health boards were reported as not suitable for use. This is based on information reported in the Welsh Immunisation System. There may be additional unusable doses that have not been recorded.

2. Background

In this release one dose refers to one dose of vaccine, whereas a course of vaccination is made up of two doses. This is the same for both types of vaccine.

NHS Wales Informatics Service (NWIS) data from the Welsh Immunisation System (WIS) is used for vaccine doses not suitable for use.

We are publishing these data to provide a weekly summary of operational vaccine activity in Wales, including doses not suitable for use, broken down by vaccine type and local health board. We are hoping to include data on stocks and distribution allocated to Wales as well as doses not suitable for use in future releases.

The launch of the programme for the Pfizer BioNTech vaccine was on 8 December 2020. On 4 January 2021, the Oxford AstraZeneca vaccine was rolled out in Wales.

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.

The data are taken from management information and are subject to change. They have not been subject to the same validation processes undertaken for official statistics releases. We are publishing these data to provide a weekly summary of vaccination operations in Wales.

This statistical release is evolving and we appreciate feedback to improve the content.

3. Quality and methodology information

Context

The data used in this release is management information which is used to support COVID-19 vaccination operations. We are publishing these data to provide a timely summary of vaccination operational activity. The data have not undergone the same level of quality assurance as official statistics, and are subject to future revisions.

NHS Wales Informatics Service (NWIS) data from the Welsh Immunisation System (WIS) is used for vaccine doses not suitable for use.

This information helps to monitor the COVID-19 Vaccination Programme.

Relevance

Daily data on the number of people who have received vaccinations is published on the Public Health Wales (PHW) Rapid COVID-19 Surveillance dashboard. The daily release shows the cumulative number of vaccinations administered – for both first and second doses. The daily figures give a timely update on the roll out of the vaccination programme, although the actual number of people vaccinated will be higher due to ongoing data entry. PHW also publish weekly, more detailed data on vaccinations through the dashboard. This includes data at local health board level and will be expanded to cover other topics over time.

Information for the public about the vaccination is available on the PHW website.

Accuracy

A digital infrastructure for scheduling appointments, recording, and reporting on vaccination activity was developed by the NHS Wales Informatics Service (NWIS) to meet the needs of the vaccination programme called the Welsh Immunisation System (WIS). Data on vaccine doses not suitable use is extracted from WIS and reflects the position as at Thursday of each week 5pm.

Some vaccination data may be recorded on paper records, which may still need to be entered at the time of data extraction and reporting. Actual numbers may vary and will be revised in future releases as more information is recorded.

Vaccine data provided by the distributor are undergoing quality assurance and as such are subject to future revision.

In this release vaccine figures are reported in terms of doses. For both vaccines each vial contains a number of doses.

The product information for the Pfizer vaccine states 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 MHRA.

The product information for the 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 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 percentage of doses unsuitable for use is calculated by using the total doses unsuitable for use by the total doses supplied to health boards.

Timeliness and punctuality

The data in this release is from 8 December 2020 onwards.

Accessibility and clarity

This statistical release has been pre-announced and then published on the Statistics and Research section of our website. It is accompanied by an Open Document Spreadsheet to allow users to have direct access to the data.

Comparability

Public Health Wales produce a daily surveillance dashboard where users can access the most up to date information on the number of COVID-19 vaccine doses administered.

Other UK countries do not currently publish data on vaccination stock and supply.

Data for COVID-19 vaccine doses administered for England is published on the COVID-19 Vaccinations pages of the NHS England website, Public Health England’s COVID-19 vaccine monitoring reports and as daily data within the GOV.UK Coronavirus (COVID-19) dashboard.

Data for COVID-19 vaccine doses administered in Scotland is published as daily data  within the Coronavirus (COVID-19): daily data for Scotland publication by Scottish Government and as weekly data within Public Health Scotland’s  COVID-19 statistical report.

National Statistics status

These statistics are not National Statistics. However, as far as has been practicable, they have been collected and validated in accordance with the pillars and principles within the Code of Practice for Statistics. We continue to develop the data collection and quality assurance process to improve the data.

These statistics have been produced quickly in response to developing world events.

Well-being of Future Generations Act (WFG)

The Well-being of Future Generations Act 2015 is about improving the social, economic, environmental and cultural wellbeing of Wales. The Act puts in place seven wellbeing goals for Wales. These are for a more equal, prosperous, resilient, healthier and globally responsible Wales, with cohesive communities and a vibrant culture and thriving Welsh language. Under section (10)(1) of the Act, the Welsh Ministers must (a) publish indicators (“national indicators”) that must be applied for the purpose of measuring progress towards the achievement of the wellbeing goals, and (b) lay a copy of the national indicators before the National Assembly. The 46 national indicators were laid in March 2016.

Information on the indicators, along with narratives for each of the well-being goals and associated technical information is available in the Well-being of Wales report.

Further information on the Well-being of Future Generations (Wales) Act 2015.

The statistics included in this release could also provide supporting narrative to the national indicators and be used by public services boards in relation to their local wellbeing assessments and local wellbeing plans.

Next update

This is currently a weekly statistical release. It will be published at 9.30am every Tuesday. We will review the frequency in line with changing user need.

The next release will be on Tuesday 2 February 2021.
