Sanofi higher dose flu vaccines preferentially recommended for adults 65+ in CDC Morbidity and Mortality Weekly Report
The CDC has updated its guidance, recommending Sanofi's Fluzone® High-Dose Quadrivalent and Flublok® Quadrivalent influenza vaccines for adults aged 65 and older. This preferential recommendation aims to reduce flu incidence and complications in this high-risk group. Clinical trials show these vaccines are more effective than standard doses, with Fluzone High-Dose reducing hospitalizations due to flu-related issues by 18% and pneumonia by 28%. Sanofi emphasizes its commitment to improving flu vaccination access for older adults.
- CDC recommends Fluzone High-Dose and Flublok Quadrivalent vaccines for adults 65+, indicating efficacy and safety.
- Fluzone High-Dose demonstrated an 18% reduction in cardiorespiratory hospitalizations and a 28% reduction in pneumonia hospitalizations compared to standard vaccines.
- Sanofi's vaccines are established as superior in efficacy for older adults, supported by extensive clinical data.
- None.
- This recommendation may help reduce the risk of the flu and flu-related complications in this high-risk population
- Fluzone® High-Dose Quadrivalent (Influenza Vaccine) and Flublok® Quadrivalent (Influenza Vaccine) are both proven to help prevent more cases of flu in older adults compared to a standard-dose vaccine as assessed in randomized controlled trials1,2
- In real-world evidence, they also demonstrated a reduction in flu-related complications.3,4
BRIDGEWATER, N.J., Aug. 26, 2022 /PRNewswire/ -- The Centers for Disease Control and Prevention (CDC) has published the updated Advisory Committee on Immunization Practices (ACIP) guidance granting preferential recommendation for specific flu vaccines in people age 65+ in its Morbidity and Mortality Weekly Report (MMWR), a journal highlighting the latest in public health news and communicating recommendations derived from science-based research.5
Sanofi's Fluzone® High-Dose Quadrivalent (Influenza Vaccine) and Flublok® Quadrivalent (Influenza Vaccine) were among the flu vaccines preferentially recommended by the CDC ACIP for adults 65+. The recommendation included the use of specific flu vaccines for adults 65+ including higher dose vaccines. If none of these are available at the time of administration, people in this age group should get any other age-appropriate influenza vaccine instead.6
Influenza disproportionately impacts the 65+ population, underrepresented communities, and people with co-morbidities such as diabetes, asthma, chronic obstructive pulmonary disease, and heart disease.7 Since 2010, the CDC estimates between

"We remain committed to ensuring adults 65 and older have access to flu vaccines, demonstrated to protect them from what really matters, such as flu-related hospitalizations due to cardiovascular events and pneumonia. While the ACIP's guidance is a good first step, as a leader in flu vaccines, we believe more can be done to provide healthcare providers with additional guidance."
About Fluzone® High-Dose Quadrivalent (Influenza Vaccine) and Flublok® Quadrivalent (Influenza Vaccine)
Flublok Quadrivalent and Fluzone High-Dose Quadrivalent are indicated for immunization against disease caused by influenza A and B strains contained in the vaccine. Flublok Quadrivalent is given to people 18 years of age and older. Fluzone High-Dose Quadrivalent is given to people 65 years of age and older.1,2
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.2,3,a,b In a meta-analysis of 15 published reports, including approximately 34 million people, those who received Fluzone High-Dose experienced approximately an
Fluzone High-Dose Quadrivalent builds on the legacy of the trivalent formulation, which was clinically proven to be
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.2
Flublok Quadrivalent is the first and only recombinant influenza vaccine for adults 18+ proven in a clinical study to be
The effectiveness of Flublok Quadrivalent was also judged by data from general day-to-day medical practice amongst more than 12 million adults 65 years and older, vaccination with Flublok Quadrivalent was compared to standard dose vaccines: this analysis of data captured during day-to-day medical practice of Medicare fee-for-service claims collected from during the 2019-2020 influenza season. A 5-vaccine relative effectiveness analysis showed Flublok Quadrivalent had
Specific characteristics of 2019-2020 season, such as varied strain circulation, may have impacted results. Study limitations include lack of access to information to confirm specific viral cases may have reduced the impact of comparisons made in the study and distortion caused by unlimited variables could have affected results. In addition, the study period was cut off at the end of February 2020 to avoid potential bias from the overlap between influenza season and the escalation of the COVID-19 pandemic in the US. This study was conducted by the FDA and Centers for Medicare and Medicaid Services.

Important Safety Information for Flublok® Quadrivalent (Influenza Vaccine) and Fluzone® High-Dose Quadrivalent (Influenza Vaccine)
Flublok Quadrivalent and 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 for Fluzone High-Dose Quadrivalent). In addition, Fluzone High-Dose Quadrivalent should not be given to anyone who has had a severe allergic reaction 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 Flublok Quadrivalent and Fluzone High-Dose Quadrivalent are 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 Flublok Quadrivalent and Fluzone High-Dose Quadrivalent may not protect all people who receive the vaccine.
For Flublok Quadrivalent, in adults 18 through 49 years of age, the most common side effects were tenderness, and/or pain where you got the shot; headache, tiredness, muscle aches, and joint pain.
