Epidemic and Pandemic Management (EPM), Global Inf. Recommended composition of influenza virus vaccines for use in the 2027 southern hemisphere influenza season. World Health Organization
Overview
For vaccines for use in the 2027 southern hemisphere influenza season, WHO recommends the following:
Egg-based vaccines
an A/Missouri/11/2025 (H1N1)pdm09-like virus;
an A/Darwin/1454/2025 (H3N2)-like virus; and
a B/Tokyo/EIS13-175/2025 (B/Victoria lineage)-like virus.
Cell culture-, recombinant protein- or nucleic acid-based vaccines
an A/Missouri/11/2025 (H1N1)pdm09-like virus;
an A/Darwin/1415/2025 (H3N2)-like virus; and
a B/Pennsylvania/14/2025 (B/Victoria lineage)-like virus.
