Sanofi Pasteur Ships First 2015-2016 Seasonal Influenza Vaccine Doses In United States

SWIFTWATER, Pa., July 14, 2015 /PRNewswire/ -- Sanofi Pasteur, the vaccines division of Sanofi (EURONEXT: SAN and NYSE: SNY), announced today that its first doses of Fluzone® (Influenza Vaccine) for the 2015-2016 influenza ("flu") season have been released by the U.S. Food and Drug Administration (FDA) for shipment. This represents the first of more than 65 million total doses of seasonal influenza vaccine manufactured by Sanofi Pasteur that will be delivered to U.S. health care providers and pharmacies beginning in July and continuing throughout the 2015-2016 flu season.

According to the U.S. Centers for Disease Control and Prevention (CDC), the single best way to prevent influenza is to get an annual vaccination, which is recommended for everyone six months of age and older, with rare exception.i,ii In fact, during the 2013-2014 season, the CDC estimated influenza vaccination prevented 7.2 million influenza-associated illnesses, 3.1 million medically attended illnesses, and 90,000 hospitalizations.iii

"Influenza is a serious respiratory illness that is easily spread and can lead to severe complications involving the heart, lung, endocrine and other organ systems, potentially leading to death," said David P. Greenberg, M.D., Vice President, Scientific & Medical Affairs, and Chief Medical Officer, Sanofi Pasteur U.S. "Vaccination is important for high-risk age groups, including children and older adults. For older adults, vaccination is particularly important given their susceptibility to influenza and its complications due to an age-related weakening of the immune system."

Sanofi Pasteur will supply a wide portfolio of Fluzone influenza vaccine options this season to meet the immunization needs of multiple age groups, from children as young as six months of age through adults 65 years of age and older:

  • Fluzone High-Dose vaccine is specially formulated for adults 65 years of age and older. As people age, the immune system weakens, which can put older adults at risk for influenza-related complications.iv Clinical data 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.v
  • Fluzone Intradermal Quadrivalent vaccine, licensed by the FDA in 2014 for adults 18 through 64 years of age, will be available for the first time this influenza season. Fluzone Intradermal Quadrivalent vaccine offers four-strain protection in a microinjection system that is convenient, efficient, and easy to use, allowing for streamlined administration by health care providers. The vaccine is administered directly into the skin through a 90 percent smaller, 1.5 mm microneedle. As the skin has a high concentration of immune cells, an intradermal vaccine is able to use the skin's natural defenses to induce a robust immune response. In addition, the microinjection system is ideal for vaccine administrators, since it has a pre-affixed needle and an integrated needle shield.
  • Fluzone Quadrivalent vaccine helps protect against four influenza strains (two A strains and two B strains), in contrast to trivalent influenza vaccines, which help protect against three strains (two A strains and only one B strain). The influenza B strain is associated with high hospitalization and mortality rates, 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 Fluzone Quadrivalent vaccine is licensed for use in people six months of age and older.
  • Fluzone vaccine, a trivalent influenza vaccine that protects against three influenza strains, is approved for use in people six months of age and older.

"Sanofi Pasteur is committed to helping people fight influenza by offering a broad range of vaccines for patients across multiple age groups," added Dr. Greenberg. "Patients should speak to their health care providers to determine which influenza vaccine option is most appropriate."

Health care providers who placed reservations with Sanofi Pasteur should expect to receive initial shipments by the end of 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 Fluzone Vaccines

Fluzone, 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 and Fluzone Quadrivalent vaccines are 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, Fluzone Quadrivalent, Fluzone Intradermal Quadrivalent, and Fluzone High-Dose vaccines include pain, redness, 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 or 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, 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 egg protein 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, Fluzone Quadrivalent, Fluzone Intradermal Quadrivalent, or Fluzone High-Dose vaccine may not protect all individuals.

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

About Influenza Vaccine Manufacturing
Direct shipments to health care providers and distributors mark the start of the influenza immunization season. While shipments will be ongoing through the influenza season, running from July through November 2015, Sanofi Pasteur began its seasonal manufacturing of the more than 65 million doses at the start of the year, following receipt of this year's influenza virus strains from the CDC.

As new influenza strains emerge and strain activity fluctuates throughout the year, each influenza season is unique. Global influenza surveillance monitors influenza activity to identify emerging and circulating strains, their respective levels of prevalence and their virulence.vii Surveillance data are studied months before the upcoming influenza season to determine which circulating strains should be selected for the upcoming season's influenza vaccine.viii Each February (for the Northern Hemisphere) and September (for the Southern Hemisphere), the World Health Organization (WHO) recommends strains for inclusion in influenza vaccines. 

Influenza vaccine production is a complex process which takes months once the strain selection is made and received by manufacturers. Not only is vaccine production complex, it is also a highly regulated process that requires quality testing at each step in the process. 

As the world's largest producer of seasonal influenza vaccine for both Northern and Southern Hemispheres, Sanofi Pasteur supplies more than 200 million doses worldwide annually.

About Influenza
Influenza is a serious respiratory illness that is easily spread and can lead to severe complications, even death. Each year in the United States, up to 20 percent of the population gets the flu and, on average, more than 200,000 people are hospitalized from influenza-related complications. Influenza seasons are unpredictable and can be severe. Depending on virus severity during the influenza season, annual deaths can range from a low of 3,000 to a high of about 49,000 people.ix Combined with pneumonia, influenza is the nation's eighth leading cause of death.x  Vaccination is safe and effective and the best way to help prevent influenza and its complications.

Children six months through eight years of age who have not previously received two doses of influenza vaccine may require two doses of vaccine for the 2015-2016 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 still have time to do so prior to the peak of influenza activity, which typically occurs in February.

Influenza vaccination is beneficial throughout the season, and even into the spring, as long as influenza viruses are still in circulation.
