Staying updated with the COVID-19 vaccination programme in the UK is essential for maintaining community immunity and protecting those most at risk.
As of May 2026, the NHS has rolled out its seasonal strategy to target specific vulnerable groups.
This guide breaks down the current eligibility, vaccine types, and booking procedures to ensure you have the latest health information.
The Spring 2026 COVID-19 booster programme officially commenced on 13 April 2026. This campaign is designed to “top up” the immunity of individuals whose protection from previous doses may be waning.
Unlike the early stages of the pandemic, the UK now utilizes a seasonal approach, similar to the annual flu jab, focusing on high-risk windows to reduce hospital admissions and severe illness.
Eligibility for the current spring dose is targeted at those most likely to become seriously ill from the virus. You are eligible if you fall into one of the following categories:
Adults aged 75 years and over (including those who turn 75 by 30 June 2026).
Residents in care homes for older adults.
Individuals aged 6 months and over who have a weakened immune system (immunosuppressed).
Eligibility for those with weakened immune systems includes a broad range of conditions.
This includes individuals undergoing chemotherapy or radiotherapy, organ transplant recipients, and people with certain genetic disorders or those taking long-term immunosuppressive treatments (e.g., systemic steroids).
If you are unsure of your status, the NHS recommends checking your eligibility online or consulting your specialist team.
The UK continues to use highly effective, MHRA-approved vaccines that have been updated to target recent variants, including Omicron sub-variants. The primary vaccines in use for the 2026 campaign are manufactured by:
Pfizer-BioNTech
Moderna
Sanofi
These “bivalent” or updated vaccines are designed to provide a broader immune response than the original formulas used in 2020.
For maximum efficacy, the NHS generally recommends waiting 6 months after your last COVID-19 dose before receiving a booster.
However, you can receive the spring vaccine as soon as 3 months after your previous dose if necessary.
The spring campaign is scheduled to conclude on 30 June 2026, so eligible individuals are encouraged to book before this deadline.
Booking an appointment is straightforward and can be done through several channels:
Online: Use the NHS National Booking Service.
Phone: Call 119 free of charge (translators are available if needed).
NHS App: Eligible users will often see a notification or booking link directly within the app.
Walk-ins: Some community pharmacies and vaccination centres offer walk-in slots, though booking is advised to guarantee a dose.
Vaccinations are no longer confined to mass vaccination centres. In 2026, the service is integrated into local primary care, including:
GP Surgeries: Many local practices now manage their own lists.
Community Pharmacies: A large number of high-street pharmacies are commissioned to provide the service.
Care Homes: Mobile teams visit care home residents directly to ensure full coverage.
Recent data from the UK Health Security Agency (UKHSA) highlights the continued success of the booster programme.
Statistics show that those who received a spring booster in previous years were approximately 55% less likely to be admitted to hospital with COVID-19 in the 2 months following vaccination.
The vaccine remains the most effective tool for preventing “Long COVID” and severe respiratory complications.
Safety monitoring remains a priority for the NHS. Most people experience mild side effects similar to previous doses, such as:
Tenderness or a “heavy” feeling in the arm.
Tiredness or fatigue.
Headaches or mild flu-like symptoms.
These usually resolve within a few days. Serious side effects, such as myocarditis, remain extremely rare and are closely monitored by the Yellow Card scheme.
Looking ahead, the UK government and the Joint Committee on Vaccination and Immunisation (JCVI) are already planning the Autumn/Winter 2026/27 campaign.
This will likely involve a wider rollout, potentially co-administered with the annual influenza vaccine.
Stay tuned to official NHS communications for updates on eligibility for the later part of the year.
