COVID-19 Booster Programme

Posted in Home

In line with the guidance set out by the Joint Committee on Vaccination and Immunisation (JCVI)the NHS Vaccination Programme will now invite eligible people, who had their second jab at least six months ago (a minimum of 182 days), for their booster dose.

Appointments for a Covid-19 booster dose can now be booked if it’s been at least five months or a minimum of 152 days since your second dose of the vaccine on the NHS website. While you will be able to book your booster if it is more than five months since your second jab, the appointment you will be offered will still be more than six months (182 days) since your last dose.  

The following people should be offered a booster dose of the COVID-19 vaccine in the same order as the first part of the vaccination programme.

  • those living in residential care homes for older adults
  • all adults aged 40 years or over
  • frontline health and social care workers
  • all those aged 16 and over with underlying health conditions that put them at higher risk of severe COVID-19 (as set out in the green book)
  • people aged 16 and over who are a main carer for someone at high risk from COVID-19
  • adult household contacts of immunosuppressed individuals


If you had your 2nd Covid-19 vaccination at least 6 months (or a minimum of 182 days) ago,  you are eligible for a booster, you can:

  • walk-in for a Covid-19 booster (without a letter, text or email from the NHS). For details of the Shropshire, Telford and Wrekin walk-in clinics please visit: COVID-19 Vaccination Walk-in and Pop-up Clinics (
  • book an appointment via the National Booking Service or by calling NHS 111. Appointments are at a time and place convenient to you and the booking system offers a range of locations including vaccination centre, GP surgeries, and community pharmacies.
  • Alternatively, if you prefer to be vaccinated at your GP surgery or primary care network (PCN) please wait to be contacted. 

The 'booster' vaccination programme is separate to the recent recommendation of third doses for people with severely weakened immune systems - something that is already being rolled out.

What is the COVID-19 booster programme?

The COVID-19 booster programme is the rollout of an additional vaccine dose to people who have previously received two doses of a COVID-19 vaccine to ensure continued protection for those most at risk from COVID-19.

Why is the COVID-19 booster programme needed?

We want to provide the people that are most likely to become seriously ill from COVID-19 and those who care for them with the best possible protection for this winter. The Joint Committee on Vaccination and Immunisation (JCVI) has reviewed available data and provided advice that COVID-19 boosters are first offered to the most vulnerable in order to provide maximum protection during the Winter months.

The flu vaccination programme is now running which protects people from serious complications from getting flu, so we would also encourage people that are eligible for a COVID-19 booster to also get their flu vaccination. More information on the flu vaccination is at

I am severely immunosuppressed. When will I get my booster?

JCVI have advised that individual who are severely immunosuppressed get an additional third dose of vaccine as part of their primary course of immunisation.  This offer is separate to the booster programme. More information is available here: JCVI issues advice on third dose vaccination for severely immunosuppressed - GOV.UK (

If I’m eligible when and where can I get my vaccination?

The NHS will let eligible people know to have their booster vaccine when it is their turn.

The JCVI advises that the booster vaccine dose should be offered no earlier than six months after having the second dose of the vaccination. Like your previous doses, the vaccine will be given in your upper arm.

People will be offered the vaccine through a range of services. Primary care teams will vaccinate care home staff and residents. Health and social care staff will be directed to book their appointments through employers and members of the public will be invited to get their booster through a GP-led service and/or be contacted by the NHS to book through the national COVID-19 vaccination booking service to get their vaccination in a designated pharmacy, vaccination centre or GP-led service.

Why aren’t most younger people being offered a booster?

As most younger adults will only have received their second COVID-19 vaccine dose in late summer or early autumn, the benefits of booster vaccination in this group will be considered at a later time when more information is available. In general, younger, healthy individuals may be expected to generate stronger vaccine-induced immune responses from primary course vaccination compared to older individuals.

What type of vaccine will the COVID-19 booster be? What if it’s different to the one I have had?

After reviewing data on booster responses from different combinations of COVID-19 vaccines, JCVI advises a preference for the Pfizer-BioNTech (vaccine to be offered as the booster dose irrespective of which type of vaccine was used in the primary schedule). There is good evidence that the Pfizer-BioNTech vaccine is well tolerated as a booster dose and will provide a strong booster response.

Alternatively, individuals may be offered a half dose of the Moderna vaccine, which should be well tolerated and is also likely to provide a strong booster response. A half dose of Moderna vaccine is advised over a full dose due to the levels of reactogenicity (side effects) seen following boosting with a full dose in clinical trials.

Where mRNA vaccines cannot be offered e.g. due to contraindication, vaccination with the AstraZeneca vaccine may be considered for those who received AstraZeneca vaccine in the primary course. More detail is available in the green book

Will there be any side effects from the booster vaccine?

As with your previous dose the common side effects are the same for all COVID-19 vaccines used in the UK.

If you had serious side effects after any previous dose you may be advised to avoid or delay further vaccination. You should discuss this with your doctor or specialist.

Can I have the booster if I haven’t completed the first vaccination course?

No, you need to finish the first course of your vaccination.

Can I get the flu and COVID-19 booster vaccine at the same time?

The COVID-19 booster and the flu vaccine can be given on the same day and for people that are eligible for both, there may be opportunities to have both together. We would encourage you to get your vaccinations as soon as possible and get fully protected rather than waiting as it may not always be possible to get them together.

I haven’t yet had the COVID-19 vaccination, can I still get my first and second jabs?

Everyone that is eligible that hasn’t already had their first or second COVID-19 vaccination will still be able to get vaccinated, even when the COVID-19 booster programme begins. This may be through a GP-led service or by booking through the NHS COVID-19 Vaccination national booking service.

Everyone aged 16 and over can book their COVID-19 vaccination appointments online for an appointment at a vaccination centre or pharmacy.

Parents of young people aged 12 - 15 years old can book their COVID-19 vaccination appointment online for an appointment at a vaccination centre or pharmacy. 

Can I get the booster if I am pregnant?

If you are pregnant and in one of the groups that the JCVI has recommended for the boosters, you are eligible to receive a booster, no earlier than six months after completion of the first course of vaccination. The NHS will contact you when it is your turn.
