Key timelines
Full details outlining the detail of the timing can be seen within the National flu immunisation programme 2026 to 2027 letter.
Pregnant women and children
Pregnant women should continue to be offered from the 01 September 2026.
As flu circulation in children normally precedes that in adults, the children’s programme should continue to start from 01 September 2026 or as soon as delivery and supply of vaccine allows.
Adults
The adult programme will commence from the 01 October 2026.
Note: Following clinical assessment there may be a small number of other adults who would benefit from vaccination from 01 September 2026. For example, for those who are due to commence immunosuppressive treatment (such as chemotherapy), having a flu vaccine before they start treatment would allow them to make a better response to their vaccination. GPs should use clinical judgement to bring forward vaccination only in these exceptional circumstances otherwise payment will not be made for adults vaccinated before October, in line with contractual arrangements.
The National Booking Service (NBS)
NBS is open from 17 August 2026 to 31 March 2027.
