Flu Shot Recommendations Issued for 2024-2025

The World Health Organization (WHO) has revealed its recommended composition for influenza vaccines for the northern hemisphere flu season of 2024-2025.

Both trivalent and quadrivalent vaccines are recommended as of February 23, 2024.

These WHO recommendations are utilized by national vaccine regulatory agencies and pharmaceutical companies to develop, produce, and license influenza vaccines for the following influenza season.

Previously, the WHO urged manufacturers to eliminate the B/Yamagata component from flu vaccines for 2024-2025.

As of February 10, 2024, over 157 million flu vaccines (egg, cell, and nasal) had been distributed in the United States during the 2023-2024 season.
