Text graphic - green background with text - Booster

Last updated 9 May 2022

Who is being offered a first booster?

A first booster dose will be offered to:

  • all people aged 16 years or over
  • certain individuals aged 12-15 including those with underlying health conditions that put them at higher risk of severe COVID-19, those who are severely immunosuppressed and who have received a third primary dose, and household contacts of people who are immunosuppressed

Information about the spring booster is available from our spring booster page.

When is the first booster offered?

Everyone aged 16 and over (and eligible 12-15 year olds) registered with a Powys GP is being invited for a first booster three months (13 weeks) after their primary course.

If you are 18+ and it is more than three months since your primary course you can attend our drop-in sessions. Boosters doses for eligible individuals under 18 are currently by appointment.

Where will the first booster be offered?

Our first booster drop-ins are now available to everyone aged 18+ regardless of where you are registered with a GP.

If you are not registered with a GP in Powys and would like a booked appointment (rather than a drop-in), please check for details in your local area.

Most first booster vaccinations will take place in mass vaccination centres in Newtown, Llanelwedd and Bronllys. This is the best way for us to offer the Pfizer vaccine (the main vaccine type recommended for the booster programme) to as many people as possible as quickly as possible.

When will I receive my first booster?

If you are 18+ and it is more than three months since you completed your primary course and you have not received your invitation please attend a drop-in session. Boosters doses for eligible individuals under 18 are currently by appointment.

Is a spring booster being offered?

Yes, to certain individuals.

The Joint Committee on Vaccination and Immunisation announced on 21 February that a spring booster should be offered in the spring around six months after their last vaccine dose to residents of care homes for older adults, people over 75 and people aged 12+ with severe immunosuppression: Joint Committee on Vaccination and Immunisation (JCVI) statement on COVID-19 vaccinations in 2022: 21 February 2022 - GOV.UK (

When will I receive my first booster if I am immunosuppressed?

Please note that some individuals who had immunosuppression at the time of their first or second dose will have been offered a third primary dose, and will then be invited for a first booster at least three months after their third primary dose. 

What should I do if I cannot attend the time I am offered?

Please do all that you can to attend at the time we have offered you. This will help us to offer as many boosters to as many people as possible, as quickly as possible. If you cannot attend the time we offer you, you may face a delay until we can offer you a new appointment.

If you receive an invitation letter and cannot attend the time we have offered you, please contact our booking team to let us know

Which vaccine type will I be offered?

Booster doses in Powys will normally be with the Pfizer/BioNTech vaccine. If a clinician has advised you not to have the Pfizer/BioNTech vaccine or you are allergic to its ingredients then please ring our booking team when you receive your appointment letter and they will be able to provide advice.

If you have not received your invitation letter and you were previously advised by a clinician providing your care NOT to have the Pfizer/BioNTech then you can contact our booking team about your booster. They will seek advice from our pharmacy team. There have been changes to vaccine guidance during 2021 which mean that many people previously advised not to have Pfizer/BioNTech are now able to receive this vaccine safely. If this applies to you please contact our booking team at with your full name and date of birth, and brief details of your enquiry.

More information about the Pfizer/BioNTech vaccine is available from the Medicines and Healthcare products Regulatory Agency (MHRA) website.

The Joint Committee on Vaccination and Immunisation has recommended that Pfizer/BioNTech or Moderna are given as boosters. We do not currently use Moderna in Powys, so Pfizer/BioNTech will be offered unless clinically contra-indicated.

Can I choose which type of vaccine I have?

No. We are not able to offer a personal choice of vaccine type for boosters.

Here in Powys we ensure that we follow the latest available clinical guidance in the UK based on recommendations from the Joint Committee on Vaccination and Immunisation (JCVI). This is an independent expert body that advises UK health departments on immunisation.

They published guidance on 14 September recommending a booster dose for certain individuals: JCVI statement regarding a COVID-19 booster vaccine programme for winter 2021 to 2022 - GOV.UK (

Their guidance is based on the latest available evidence on the effectiveness of different vaccine types for reinforcing immunity. They have made a clear recommendation that Pfizer/BioNTech or alternatively Moderna should be offered as the booster. AstraZeneca should only be provided in specific circumstances – such as where there is a clinical contraindication to the use of an mRNA vaccine and where AstraZeneca was offered in the primary course.

This guidance is reflected in the “Green Book” (this is the detailed national guidance on immunisation programmes) and is therefore also reflected in detailed local documentation called “Patient Group Directions” that provides the framework for all of our clinical staff to administer vaccines both safely and effectively. All staff are asked to operate within this framework.

In Powys we do not use Moderna as part of our COVID-19 booster programme and therefore Pfizer/BioNTech is the booster vaccine we offer to everyone for whom it is clinically suitable. For those people with specific clinical contraindications (e.g. allergy to the active substance or ingredients of the Pfizer/BioNTech vaccine) we are able to put in place arrangements to offer AstraZeneca as an alternative.

Where can I find out more about the COVID-19 Vaccine?

More information is available from the Public Health Wales website.

Where can I report adverse effects?

Reports of adverse events can be reported through the MHRA Coronavirus Yellow Card page 

Please do not contact your health board or GP practice for a booster vaccination.
