The latest addition to Sanofi Pasteur's flu vaccine offerings is Flublok Quadrivalent vaccine, which will be available to more providers across the country compared to previous seasons.

"This past flu season was a stark reminder of how unpredictable flu can be. It is important to get vaccinated even if vaccine effectiveness is lower than we would like. Vaccination saves many lives, helps prevent numerous hospitalizations, and helps protect individuals and the public at large from severe, life-threatening complications," said David P. Greenberg, M.D., Associate Vice President and Regional Medical Head North America, Sanofi Pasteur. "We are proud that in recent years we have introduced two vaccines proven to help prevent more flu than their respective standard-dose flu vaccine comparators in older adults. We are dedicated to continuing to find new ways to improve flu vaccines, particularly for those most impacted every year."

Improved Flu Vaccines to Help Protect Most Vulnerable Groups

Fluzone High-Dose vaccine: The first and only flu vaccine shown to have superior efficacy compared to Fluzone vaccine in helping to protect against the flu in adults 65 years of age and older (24.2 percent more effective).1 In additional studies, Fluzone High-Dose vaccine has also been shown to be more effective at preventing flu-like illness and flu-associated hospitalizations, pneumonia and cardiorespiratory events in older adults, compared to standard-dose flu vaccine.2  Sanofi Pasteur anticipates that two-thirds of all adults 65 years of age and older who will get a flu shot in the United States will receive Fluzone High-Dose vaccine. 

Flublok Quadrivalent vaccine: Indicated for adults 18 years of age and older, and proven to help prevent more cases of flu in people 50 years of age and older compared to standard-dose quadrivalent inactivated flu vaccine (30 to 43 percent more protection).3 Flublok Quadrivalent vaccine is the only recombinant protein-based flu vaccine approved by the U.S. Food and Drug Administration (FDA), uniquely providing an exact genetic match of hemagglutinin (HA) from each recommended vaccine virus. HA is the protein identified as key to stimulating immunity to the flu.

Fluzone Quadrivalent vaccine: Helps protect against four flu strains (two A strains and two B strains) and was the first four-strain flu vaccine licensed for use in people 6 months of age and older.

Sanofi Pasteur is the nation's largest supplier of flu vaccines for people 6 months of age and older, including the only two flu vaccines proven to help prevent more flu cases in older adults, compared to their standard-dose flu vaccine comparators.

Fluzone High-Dose vaccine is approved for use in persons 65 years of age and older.

Before administration, please see the full Prescribing Information for Flublok Quadrivalent, Fluzone Quadrivalent or Fluzone High-Dose vaccine. Also, please see complete Patient Information for Fluzone Quadrivalent or Fluzone High-Dose vaccine.

About Influenza 
Each year, about up to one out of every five Americans gets the flu and, on average, more than 200,000 people are hospitalized from flu-related complications.4 Flu seasons are unpredictable, with flu-related deaths ranging from 3,000 to as high as 49,000 people each year.5 Combined with pneumonia, the flu is one of the top 10 leading causes of death in the United States.6

Health officials recommend everyone 6 months of age and older, with rare exception, get a flu shot every year. Certain groups are at increased risk, including:  children 5 years of age and younger, pregnant women, adults 50 years of age and older, and people with serious medical conditions like diabetes, cardiovascular disease, asthma and other chronic conditions.7

Fluzone High-Dose Vaccine Fact Sheet

 

Flublok Quadrivalent Vaccine Fact Sheet

 

Sanofi Pasteur, the world's largest manufacturer of influenza (flu) vaccines, relies on an egg-based production process to produce Fluzone® High-Dose (Influenza Vaccine) and Fluzone® Quadrivalent (Influenza Vaccine). After the U.S. Food and Drug Administration (FDA) approves the composition of the flu vaccine, candidate vaccine viruses (CVVs) are injected into chicken eggs, a step known as inoculation. The eggs are incubated for several days to allow for virus replication.

 

Next comes the harvest. Virus-containing fluid is drawn from the eggs. The fluid is filtered to capture the flu viruses, which are inactivated (killed). Since it takes approximately one egg to produce one vaccine, Sanofi Pasteur's Swiftwater campus receives nearly one million eggs each day during the production season.

 

In addition to egg-based vaccines, Sanofi Pasteur is now offering Flublok® Quadrivalent (Influenza Vaccine), which is manufactured using an egg-free recombinant DNA technology. This process produces an exact genetic match to the binding proteins found on the surface of the flu virus. It starts by isolating the hemagglutinin (HA) protein from the selected FDA virus strains. The HA protein, which induces an immune response in people, is transcribed into a DNA sequence.

 

The host cells are reprogrammed to rapidly produce large quantities of the antigen for use in the flu vaccine. The antigens are separated and collected from the host cells, purified, and formulated as Flublok Quadrivalent vaccine. After quality control testing, which includes testing by the FDA, syringes are filled and shipped to healthcare providers. Once the vaccine is administered, the antigen stimulates the body's immune system to produce antibodies that can neutralize the flu virus.
