Anyone can catch and spread flu. It’s an infectious disease that does more damage than most people realize. It can lead to severe complications, increasing the risk of heart attack and pneumonia.
Flu impacts people’s lives and puts a considerable strain on already stretched health systems during the winter season. Vaccines are the best public health tool available to prevent flu and its serious complications.
But not all flu vaccines are the same. We believe we must protect beyond the influenza infection to help reduce the risks of its severe complications, which too often bring people to hospital.
Facts about Flu
Flu can wreak havoc
across major organ systems2,3,4,5
By up to 45%
Influenza vaccination can reduce the risk of heart attacks by up to 45% [15-45%]7
Vaccination is especially important for people most at risk1
People over 65, children under 5, pregnant women and people with chronic medical conditions
Flu and Covid-19 vaccines can be administered at the same time8 per a recent Sanofi study9
Flu is unpredictable and can be severe1
The Real Burden of Flu
- Flu can cause a 10X increased risk of heart attack within the week following a flu infection2
- Flu can increase your risk of stroke and pneumonia X82,5
Protection Beyond Flu
“With our influenza vaccines, we seek to not only prevent influenza but also protect against its severe complications like heart attack and pneumonia. We aim to ensure these vaccines, supported by a high level of evidence, are available to protect as many people as possible each flu season.”

Innovation for Flu and Beyond
We are pursuing next generation influenza vaccines with multiple vaccine technologies to develop and bring forward tomorrow’s vaccines to people around the world as fast as possible.
That means not only using mRNA or protein-based technologies, but also novel methods of antigen selection in order to induce broader protection.
We are currently innovating in our existing different technologies including egg-based flu vaccines, recombinant proteins, mRNA to develop and deliver vaccines that can protect as many people as possible against flu and its complications.
