Seasonal influenza activity typically occurs between October and May and peaks between December and February. However, influenza activity peaked noticeably late last season occurring in early March 2016.1 Influenza seasons are always unpredictable as new influenza strains emerge and strain activity fluctuates throughout the year, making timely vaccination even more important to help protect against the virus, especially for seniors, young children and infants six months of age and older.

The Centers for Disease Control and Prevention (CDC) recommends annual influenza vaccination for everyone six months of age and older, with rare exception, and recommends receiving the vaccine as soon as it is available to help with prevention even before the season begins. In the 2015-2016 influenza season, 50 percent of seniors who were vaccinated received Fluzone High-Dose vaccine, and this number is expected to rise to 60 percent in the coming season.

"There is general awareness of influenza among the public given its widespread prevalence," said David P. Greenberg, M.D., Associate Vice President and Regional Medical Head North America, Sanofi Pasteur. "What is not well known is that influenza can be life-threatening and have a lasting health impact, especially for the most vulnerable populations. In the 2014-2015 season, the CDC estimated 40 million flu illnesses, 19 million flu-associated medical visits and almost 1 million flu-associated hospitalizations."2

As the single largest provider of influenza vaccine to the United States, Sanofi Pasteur provides a wide range of influenza vaccine options. The Fluzone vaccine portfolio meets immunization needs across the entire lifespan, from children as young as six months of age through adults 65 years of age and older, and includes the following products:

  • Fluzone High-Dose vaccine, the first influenza vaccine designed specifically for people 65 years of age and older, is an inactivated influenza vaccine.3 Fluzone High-Dose vaccine is the only influenza vaccine for seniors that the U.S. Food and Drug Administration (FDA) has approved as having demonstrated superior efficacy against influenza compared with Fluzone vaccine. It contains four times the antigen content of Fluzone vaccine to help promote a stronger immune response to influenza.4 Clinical data published in TheNew England Journal of Medicine demonstrated that Fluzone High-Dose vaccine was 24.2 percent more effective than Fluzone vaccine in preventing laboratory-confirmed influenza caused by any influenza viral type or subtype in association with influenza-like illness, in adults 65 years of age and older.4 A secondary endpoint demonstrated Fluzone High-Dose vaccine was 51.1 percent more effective than Fluzone vaccine against influenza caused by viral strains antigenically similar to those contained in the vaccine using a modified CDC influenza-like illness definition.4


  • Fluzone Quadrivalent vaccine helps protect against four influenza strains (two A strains and two B strains). The influenza B strain is associated with substantial hospitalization and mortality, especially in children and young adults. In fact, on average, over multiple recent seasons, 34 percent of influenza-related deaths in children up to 18 years of age were due to influenza B.5 Fluzone Quadrivalent vaccine is the first four-strain influenza vaccine licensed for use in people six months of age and older.


  • Fluzone Intradermal Quadrivalent vaccine was licensed by the U.S. Food and Drug Administration (FDA) in 2014 for adults 18 through 64 years of age. Fluzone Intradermal Quadrivalent vaccine is administered directly into the skin using a 90 percent smaller, 1.5 mm microneedle and offers four-strain protection that is convenient, efficient, and easy to use, allowing for streamlined administration by health care providers.

"Sanofi Pasteur is at the forefront of influenza vaccine innovation," said Dr. Greenberg. "Our legacy for researching and manufacturing influenza vaccines has existed for nearly 70 years at our Swiftwater-based facility, demonstrating our experience and commitment to this important public health need. We are dedicated to continuously improving our influenza vaccine options to ultimately help protect against influenza strains, including drifted strains that may occur in the future."

To address recommendations by the Advisory Committee on Immunization Practices (ACIP), Sanofi Pasteur has increased production of Fluzone Quadrivalent vaccine where possible. Sanofi Pasteur is the sole provider of injectable influenza vaccine for pediatric patients six months through 35 months of age.

Health care providers who placed reservations with Sanofi Pasteur should expect to receive initial shipments between late July and early August to support fall immunization campaigns. Health care providers wishing to reserve vaccine can do so by visiting or by calling 1-800-VACCINE (1-800-822-2463).

About Influenza
Influenza is a serious respiratory illness that is easily spread and can lead to severe complications, even death. Each year, one out of every five Americans gets the flu and, on average, more than 200,000 people are hospitalized from influenza-related complications.6 Influenza seasons are unpredictable with flu-related deaths ranging from 3000 to as high as 49,000 people.7 Combined with pneumonia, influenza is one of the top ten leading causes of death in the United States.8 Vaccination is safe and effective and the best way to help prevent influenza and its complications.

Children six months through eight years of age may require two doses of vaccine for the 2016-2017 influenza season. Parents should consult their health care provider about the number of doses of influenza vaccine their child should receive.  

Individuals who are not immunized early in the season will still have time do so as the influenza vaccination is beneficial throughout the season, even into the spring, as long as influenza viruses are still in circulation.9

About Fluzone Vaccines

Fluzone Quadrivalent, Fluzone Intradermal Quadrivalent, and Fluzone High-Dose vaccines are given to help prevent influenza disease caused by influenza A and B strains contained in each vaccine.

Fluzone Quadrivalent vaccine is given to people 6 months of age and older. Fluzone Intradermal Quadrivalent vaccine is given to people 18 through 64 years of age. Fluzone High-Dose vaccine is given to people 65 years of age and older.

Safety Information
Side effects to Fluzone Quadrivalent, Fluzone Intradermal Quadrivalent, and Fluzone High-Dose vaccines include pain and swelling at the injection site (also itching in adults receiving Fluzone Intradermal Quadrivalent vaccine); muscle aches, fatigue, headache, and fever (also irritability, abnormal crying, drowsiness, appetite loss, and vomiting in young children receiving Fluzone Quadrivalent vaccine). Itching, redness, swelling, and firmness at the injection site occurred more frequently with Fluzone Intradermal vaccine (containing 3 influenza strains) than with Fluzone vaccine. Other side effects may occur.

Fluzone Quadrivalent, Fluzone Intradermal Quadrivalent, and Fluzone High-Dose, vaccines should not be administered to anyone with a severe allergic reaction (e.g., anaphylaxis) to any vaccine component, including eggs, egg products, or thimerosal (the multidose vial is the only presentation containing thimerosal), or to a previous dose of any influenza vaccine.

Tell the doctor if you/your child has ever experienced Guillain-Barré syndrome (severe muscle weakness) after a previous dose of influenza vaccine. If you notice any other problems or symptoms following vaccination, please contact your health care professional immediately. Vaccination with Fluzone Quadrivalent, Fluzone Intradermal Quadrivalent, or Fluzone High-Dose vaccine may not protect all individuals.

For more information about Fluzone Quadrivalent, Fluzone Intradermal Quadrivalent, or Fluzone High-Dose vaccine, talk to your health care professional and see complete Patient Information.
