Key timelines

Pregnant women and children

  • Pregnant women should continue to be offered from the 1 September 2025.
  • As flu circulation in children normally precedes that in adults, the children’s programme should continue to start from 1 September or as soon as delivery and supply of vaccine allows.

Adults

  • The adult programme for 2025 to 2026 will again be from the beginning of October (exact date to be confirmed, be aware that reimbursement will be tied to this date)
  • Following clinical assessment there may be a small number of other adults who would benefit from vaccination from 1 September. 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.

Full details outlining the detail of the timing can be seen within the National flu immunisation programme 2025 to 2026 letter.
