Why is the UK experiencing an early and severe flu season?
The 2025 flu season started five weeks earlier than usual, influenced by Australia's record-breaking flu season and recent epidemics in the Asia-Pacific region. The dominant H3N2 strain has undergone significant mutations, reducing the effectiveness of current vaccines and leading to more widespread infections and hospitalizations.
