His Royal Highness The Duke of Edinburgh, 10 June 1921 to 9 April 2021

Read about the arrangements following The Duke of Edinburgh’s death

This weekly statistical release includes management information on the number of COVID-19 vaccine doses allocated to Wales and local health boards, and the number of doses not suitable for use. 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.

Main results

  • 2,010,750 doses of COVID-19 vaccine have been allocated to Wales.
  • 1,742,440 doses of COVID-19 vaccine have been delivered to Wales.
  • 0.5% of vaccine doses were reported as not suitable for use. Split by vaccine type, 0.9% of Pfizer BioNTech and 0.1% of Oxford/AstraZeneca vaccine doses were reported as not suitable for use.

Background

The total number of doses allocated refers to the number of doses that have either been made available by Public Health England to the Welsh Government for ordering (up to 11:55 on 22 March 2021) or, in the case of the Pfizer/BioNtech vaccine, delivered direct from the manufacturer to Wales (up to the end of 22 March 2021).

Total number of doses delivered refers to the number of doses that have either been delivered from Public Health England to the ownership of the Welsh Government 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 on 21 March 2021.

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

Number of doses includes both Pfizer/BioNTech and AstraZeneca doses.

Figures on doses allocated and delivered refer 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.

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

NHS Wales Informatics Service (NWIS) 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 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. PHW and Velindre receive an allocation relative to the number of employees classified as frontline healthcare workers in accordance with JCVI criteria. Velindre receive an allocation for vaccinating employees of the Welsh Ambulance Service Trust and individuals under the care of Velindre Cancer Centre who are also in JCVI priority groups.

Pfizer BioNTech vaccines are delivered directly to Wales by the manufacturer. The Welsh Government’s distributor delivers the Pfizer BioNTech vaccine to mass vaccination centres, hospitals and GP practices. The Oxford / AstraZeneca vaccine is delivered by Public Health England’s distributor directly to hospitals and GP practices and other primary health care settings.

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.

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

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.

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.

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 5pm on the Sunday of each week.  

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.

For Oxford/AstraZeneca the total doses received is the total supplied to health boards by PHE’s distributor. The number of doses received and number of doses supplied is therefore the same for Oxford/AstraZeneca. The total Pfizer doses received include those delivered to health board vaccination centres and GPs and any stock not yet delivered by the distributor for health boards to draw upon.

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

Prior to 26 January 2021 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 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 percentage of doses unsuitable for use is calculated by using the total doses unsuitable for use by the total doses administered plus total doses unsuitable for use.

Timeliness and punctuality

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

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 Senedd Cymru. 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.
