Coronavirus: vaccination data

Published 01/04/2021   |   Last Updated 07/04/2021   |   Reading Time minutes

Senedd Research stops publishing new research and analysis during the pre-election period, from 7 April to 6 May. This article won’t be updated during this time. You can find links to the most recent data and information in our Coronavirus (COVID-19) signposting article.


The Welsh Government published an updated vaccination strategy for the rollout of COVID-19 vaccines in March. The strategy sets three milestones with broad timings for when the adult population of Wales will be offered a first dose of a vaccine. The Welsh Government aims to offer a vaccine to all eligible adults by 31 July 2021.

Public Health Wales (PHW) publishes a monthly report on inequalities in vaccine uptake. Our article: ‘Who’s being left behind in the coronavirus vaccination rollout’ explores this data further.

How many people have received a dose of a vaccine?

As of 1 April 2021, Wales has administered 1,443,885 first doses of a COVID-19 vaccine, which accounts for 45.8% of its total population.

Note: The population of each UK nation is based on most recent Office for National Statistics data and therefore includes those under the age of 16 who won’t be offered a COVID-19 vaccine.

You might see different population percentages being used in relation to the vaccination rollout. Some sources compare vaccine doses to the total population and others compare doses to the population aged 16 and over as there is currently no plan to vaccinate those under 16. We are presenting both to show the difference.

The map above shows how Wales compares to the other UK nations on the percentage of the total population who have received their first and second dose.

The graph below show the percentage of the population aged 16 and over who have received their first and second dose of a vaccine over time.

How is the rollout in Wales progressing?

The first and second milestones

The first vaccination strategy milestone was to have offered a first dose of a vaccine to everyone in priority groups 1 to 4 by mid-February 2021. This included:

  • 1. People living in a care home for older adults and their staff carers;
  • 2. People aged 80 and over, and frontline health and social care workers;
  • 3. people aged 75 and over, and
  • 4. People aged 70 and over and those people who are clinically extremely vulnerable (previously shielding).

On 12 February the First Minister for Wales, Mark Drakeford, announced that the first milestone had been met.

The second vaccination milestone is to offer the first dose of a COVID-19 vaccine to priority groups 5 to 9 by the middle of April 2021. This milestone includes:

  • 5. people aged 65 and over;
  • 6. those over the age of 16 with an underlying health condition;
  • 7. people aged 60 and over;
  • 8. people aged 55 and over; and
  • 9. people aged 50 and over.

The overall progress toward milestones one and two are shown in our charts below for first and second doses.

The Welsh Government says that “vaccination is not mandatory, therefore, it is possible we may not reach 100% of every cohort because some people will choose not to have the vaccine”.

The third milestone

The third vaccination milestone represents the second phase of the vaccination programme. The Welsh Government’s aim is to offer to a first dose of a vaccine to those aged 18-49, by the end of July 2021.

The Joint Committee on Vaccination and Immunisation (JCVI) provides advice to the four governments of the UK on the prioritisation of the vaccines. In February the JCVI advised that vaccine deployment should continue on the basis of age.

There are calls for occupations which are at an increased risk from COVID-19 to be prioritised. However, the JCVI says this would be “more complex to deliver” and would “slow down vaccine delivery to the population as a whole”. Based on the JCVI’s recommendations, the third milestone will be broken down into the following groups:

  • people aged 40-49;
  • people aged 30-39; and
  • people aged 18-29.

How is the rollout progressing in each health board?

PHW publishes the number of reported doses given by each health board, and the proportion of some of the priority groups that have received a first and second dose.

The two graphs below show progress by local health board.

A lack of detailed data

In January the Office for Statistics Regulation (OSR) wrote to UK administrations, including the Welsh Government and PHW, about the publication of vaccination data.

It emphasised the importance of the data for assessing whether the governments are meeting their vaccination targets.

The OSR has called for more progress in the following areas:

  • more detail by age group, ethnic group and the JCVI priority groups;
  • which vaccine people are receiving (Pfizer/BioNTech or AstraZeneca); and
  • information on those who have been offered a vaccine and those who have taken them up to understand why some people may not be receiving a vaccine.
