- The 2025/26 flu vaccine is 70-75% effective in preventing hospital visits for children aged 2-17 and 30-40% effective for adults.
- A new influenza A(H3N2) subclade (K) is dominant in England, but the vaccine still offers significant protection.
- Flu activity has risen unusually early this season, primarily affecting teenagers, young adults, and younger children, with 84% of cases identified as H3N2.
- High vaccine effectiveness in children may indirectly protect other groups by reducing transmission.
- UKHSA emphasizes the importance of vaccination for eligible groups, including children, adults over 65, pregnant women, and those with certain health conditions.
- Good respiratory hygiene, such as handwashing and ventilation, is crucial to prevent flu spread.
