The World Health Organization (WHO) has announced recommendations for the viral composition of influenza vaccines for the 2026-2027 northern hemisphere influenza season. These recommendations were made following a 4-day consultation.

The WHO issued recommendations based on global influenza surveillance data, stating "The announcement was made following a 4-day consultation examining global influenza surveillance data." This year's influenza vaccine composition takes into account various flu strains, including A/Victoria/2571/2021 and B/Victoria/02/2015.

According to the WHO Health department, "The announcement was made following a 4-day consultation examining global influenza surveillance data." The global influenza surveillance data informed the composition of the vaccine, ensuring that the next year's vaccine will provide optimal protection against various flu strains.

The WHO Health department plans to continue monitoring global influenza surveillance data to inform future vaccine recommendations. This proactive approach aims to provide the most effective protection against influenza viruses for the northern hemisphere population for the 2026-2027 influenza season.
