Sanofi has begun shipped its first influenza (flu) vaccines across the U.S. in preparation for the 2024–25 flu season.

Following this first shipment, additional shipments of the full Sanofi flu vaccine portfolio will continue through October to healthcare provider offices, pharmacies and other immunizers to support fall immunization campaigns. With over 125 years of heritage in helping protect global public health, Sanofi is a world leader in vaccines, helping to vaccinate more than 500 million people annually.

Thomas Grenier, Head of Vaccines, North America, Sanofi said, "Today, we began shipping flu vaccines for the upcoming season, a moment that underscores our long-standing commitment to providing global protection against disease. Getting a flu shot is imperative to not only help protect against flu infection, but also to help reduce the risks of its potentially severe complications, which can lead to hospitalizations, especially in those most vulnerable. Sanofi understands what these populations need out of their flu shots and works tirelessly from start to finish to provide proven and specific solutions."

All flu vaccines provided by Sanofi to the US market are trivalent, meaning they offer protection against the current three strains of influenza (two influenza A strains and one influenza B strain). These strains were selected based on a collaborative review of influenza surveillance by the US Food and Drug Administration (FDA), World Health Organization (WHO), the Centers for Disease Control and Prevention (CDC), among other public health experts, as the strains most likely to cause illness in the upcoming flu season.

Annual flu vaccination is one of the best ways to help protect against flu and its complications. Public health authorities worldwide reiterate their recommendations for eligible people to be vaccinated every year.

As one of the largest providers of influenza vaccines to the United States with a range of options, Sanofi meets immunization needs across the lifespan, from children as young as six months of age through adults 65 years of age and older. This year's 2024/25 US influenza season portfolio includes Fluzone High-Dose (Influenza Vaccine), Flublok (Influenza Vaccine) and Fluzone (Influenza Vaccine).

Fluzone, Flublok, and Fluzone High-Dose are vaccines indicated for the prevention of disease caused by influenza A and B strains contained in the vaccine. Fluzone is given to people 6 months of age and older. Flublok is given to people 18 years of age and older. Fluzone High-Dose is given to people 65 years of age and older.

Fluzone, Flublok, or Fluzone High-Dose should not be given to anyone who has had a severe allergic reaction to any component of the vaccine (including eggs or egg products for Fluzone and Fluzone High-Dose). In addition, Fluzone and Fluzone High-Dose should not be given to anyone who has had a severe allergic reaction after a previous dose of any influenza vaccine.
