With our influenza vaccines, we seek not only to prevent influenza but also to protect as many people as possible from its severe complications, supported by the highest level of evidence.

Did You Know?

Flu can wreak havoc on major organs and systems.(1-5)

Influenza can worsen symptoms of other chronic diseases and can lead to hospitalization. (2)

People under 5, over 65, pregnant, or living with chronic conditions are the most at risk of severe complications from flu. (1)

Innovating to Continue to Protect Beyond Flu
Not all flu vaccines are the same. We’re using mRNA, protein-based technologies, and novel antigen-selection methods to develop next generation vaccines, designed to induce broader protection against different strains of the influenza virus. We never stop innovating on our existing technologies, which help us protect people everywhere against flu and its complications.


The Real Burden of Flu
Flu is an unpredictable infectious disease and can be severe (2).
- Flu can cause a 10X increased risk of heart attack within the week following an influenza infection. (1)
- Flu can increase your risk of stroke and pneumonia X8 (1,5)
- Flu vaccination can reduce the risk of flu triggered heart attacks by up to 45% (6).
That’s why vaccination is so important, especially for people at increased risk of severe infection (2).
