Influenza (Flu)
There are approximately a billion cases of seasonal influenza annually. It's an infectious disease that can be caught and spread, leading to millions of severe illness cases and hundreds of thousands of deaths each year.¹
The best way to help protect from the virus is an annual flu vaccination.2 It has been shown to help lower the risk of catching the flu as well as help reduce the severity of illness for those who still experience symptoms of the flu.2
At Sanofi, we're committed to spreading awareness of the severity of the flu to help reduce the impact of this potentially debilitating infectious disease through timely vaccination.
Spotlight on … Assessing the Impact of Previous Influenza Seasons – Flunomics
Marked by high hospitalization rates and significant mortality among adults aged 50 and over, the 2024/2025 influenza season represented one of the worst experienced in 15 years in the United States.3,4,5,6
Flunomics turns numbers into signals. It effectively highlights the areas where older adults remain vulnerable and where health systems need to strengthen their response to avoid repeating the same challenges.

Some People Are More at Risk
While anyone can get the flu, certain groups are at increased risk of getting sick from flu and developing complications. High-risk individuals include anyone who has a chronic health condition, young children, pregnant women, older adults, and certain racial and ethnic minority groups.7
Older Adults
Respiratory Conditions
Heart Disease
Diabetes
Pregnant Women
Our Continued Commitment
At Sanofi, we've been working to help protect the public from the flu and its complications for over 70 years. We've continually integrated advanced technology and approaches, including egg-based flu vaccines, recombinant proteins, and mRNA, into our work to provide the protection needed.
