The UK Health Security Agency (UKHSA) has published its annual flu immunisation programme correspondence, setting out how the national vaccination effort will be structured for the 2026 to 2027 season.
The document, which serves as formal guidance ahead of the upcoming flu season, identifies which population groups will be eligible to receive a flu vaccine under the national programme. This type of annual correspondence is a routine part of how public health authorities communicate immunisation policy to healthcare providers and commissioners across the country.
What the Correspondence Covers
According to the UKHSA, the letter defines the eligible groups for immunisation and outlines the broader framework of the national flu vaccination programme. The agency releases this guidance on a yearly basis to reflect any changes in policy, vaccine availability, or epidemiological priorities ahead of each winter season.
Details on specific eligible cohorts, delivery mechanisms, and any updates to previous programme structures are contained within the full published correspondence, available via the official UKHSA publication.
Annual Flu Programme Planning
The national flu immunisation programme is reviewed and updated each year. The annual letter format allows the UKHSA to issue timely guidance that reflects the most current evidence and policy decisions, ensuring that those responsible for delivering vaccinations have clear direction well in advance of the season.
Flu vaccination programmes in the UK have historically targeted groups considered at higher risk of serious illness, as well as those whose roles may bring them into contact with vulnerable individuals. The precise composition of eligible groups can shift from year to year based on updated public health assessments.
The 2026 to 2027 plan represents the latest iteration of this ongoing public health effort, with the published correspondence acting as the primary reference point for programme delivery across England.
