EU recommendations for 2026/2027 seasonal flu vaccine composition

WHY IT MATTERS

Patients with rare immunodeficiency disorders or chronic conditions that increase flu risk should know which vaccine formulations their doctors may recommend, as the strain composition affects how well the vaccine protects them.

The European Medicines Agency has updated its recommendations for which flu virus strains should be included in flu vaccines for the 2026-2027 season. These recommendations apply to different types of flu vaccines, including those made using eggs and live weakened virus versions. The update was announced in May 2026 to help vaccine manufacturers prepare the right vaccines for the upcoming flu season.
