CAMBRIDGE, MA – February 22, 2022. The CDC’s Advisory Committee on Immunization Practices (ACIP) is currently evaluating data to provide guidance for influenza (flu) vaccines for adults 65+ years. With a broad-base of experience and scientific evidence with Fluzone High-Dose Quadrivalent (Influenza Vaccine), Sanofi is urging ACIP to adopt a recommendation for Fluzone High-Dose Quadrivalent as the preferred vaccine for adults 65+ years.
Recommendations for influenza vaccines for those 65 years and older have not changed since 2010.3 Recent estimates showed that 70-85% of flu-related deaths and 50-70% flu-related hospitalizations occurred in adults 65 years and older.4 Now is the time for ACIP to take action to ensure its recommendation for our 65+ population takes into account the full breadth of evidence regarding the prevention of flu and its related complications.
Executive Vice President of Vaccines at Sanofi
“Sanofi is committed to public health and collaborates with policy makers and the healthcare professional community to implement evidence-based policies to ensure that vulnerable populations have better access to vaccines that provide superior protection from the flu. We believe more can be done to protect the most vulnerable from influenza and its related complications. By making clinically-driven recommendations for the use of tailored influenza vaccines for older persons, as already done by other health authorities outside the U.S., the burden caused by seasonal influenza on the healthcare system can be relieved.”
Influenza disproportionately impacts people over 65, people of color, and people with co-morbidities such as diabetes, asthma, chronic obstructive pulmonary disease, and heart disease.5 These populations require clear recommendations rooted in science than what ACIP guidelines currently provide. Additionally influenza can lead to potentially life-threatening complications, including pneumonia or serious heart conditions, especially in older adults.6,7 Fluzone High-Dose Quadrivalent has the potential to help lower the burden of disease in this population with the greater risk for severe-flu related complications, hospitalizations and death.
With protection against four flu strains, Fluzone High-Dose is the only influenza vaccine licensed for use in adults 65 years of age and older to have demonstrated superior efficacy in a randomized controlled trial versus a standard dose influenza vaccine for the prevention of laboratory-confirmed influenza illness and the only influenza vaccine with 10 years of data demonstrating protection from flu and its related complications.1,2* In a real-world analysis of approximately 34 million people, those who received Fluzone High-Dose experienced an 18% reduction in cardiorespiratory hospitalizations and over a 27% decrease in pneumonia hospitalizations, both of which are reductions above what the standard dose vaccines provided.2

“Flu vaccination is one of the most important tools we have for protecting the public’s health, especially for adults 65 years and older who may suffer the greatest burden and these populations require clear recommendations rooted in science than what ACIP guidelines currently provide.4 Available scientific data clearly support Fluzone High-Dose (Influenza Vaccine) as being more effective at preventing influenza infection and hospitalization in this population than a standard dose vaccine.1,2
A decision to designate Fluzone High-Dose as the preferred flu vaccine for older adults could help avoid unnecessarily compromising the health of those who are already at higher risk for severe flu-related complications. We look forward to working with ACIP, as these discussions are vital to the health of older adults across the country.”
*Proven superiority in a clinical trial between Fluzone High-Dose (Influenza Vaccine) (trivalent formulation) and a standard-dose influenza vaccine1
*Includes 10 years of evidence (2009-2019) with Fluzone High-Dose (trivalent formulation)2
About Fluzone High-Dose Quadrivalent
Fluzone High-Dose Quadrivalent is a vaccine indicated for prevention of influenza disease caused by influenza A and B strains contained in the vaccine. Fluzone High-Dose Quadrivalent is given to people 65 years of age and older.1
Fluzone High-Dose is the only vaccine approved by the U.S. FDA for superior flu protection in adults 65 years of age and older, compared to a standard-dose flu vaccine.1 With 4-strain protection, Fluzone High-Dose Quadrivalent builds on the legacy of the trivalent formulation, which was clinically proven to be 24.2% more effective at preventing flu than standard-dose Fluzone (Influenza Vaccine) in adults 65+.8 Based on data from Fluzone High-Dose (Influenza Vaccine), side effects were slightly more frequent after vaccination with Fluzone High-Dose compared to a standard-dose vaccine.1
In addition, Fluzone High-Dose has demonstrated protection against influenza and its related complications including cardiorespiratory events, pneumonia and hospitalization.2
The efficacy of trivalent formulation is relevant to Fluzone High-Dose Quadrivalent since both products are manufactured according to the same process and have overlapping compositions.1
Outside of the U.S., Sanofi's High-Dose influenza vaccine has also earned recommendations for use over standard-dose influenza vaccine in individual adults 65 years and older by the National Advisory Committee on Immunization (NACI) in Canada, along with a recommendation for priority use in older adults by Germany's Standing Committee on Vaccination (STIKO).9,10
Important Safety Information
Fluzone High-Dose Quadrivalent should not be given to anyone who has had a severe allergic reaction to any component of the vaccine, including eggs or egg products, or after previous dose of any influenza vaccine.
Tell your health care provider if you have ever had Guillain-Barré syndrome (severe muscle weakness) after a previous influenza vaccination.
If Fluzone High-Dose Quadrivalent is given to people with a compromised immune system, including those receiving therapies that suppress the immune system, the immune response may be lower than expected.
Vaccination with Fluzone High-Dose Quadrivalent may not protect all people who receive the vaccine.
For Fluzone High-Dose Quadrivalent, in adults 65 years of age and older, the most common side effects were pain, redness, and/or swelling where you got the shot; muscle ache, headache, and general discomfort. Other side effects may occur.
