Flublok® and Fluzone® High-Dose are vaccines indicated for the prevention of disease caused by influenza A and B strains contained in the vaccine. Flublok® is given to people 18 years of age and older. Fluzone® High-Dose is given to people 65 years of age and older.
Flu and its complications could be lurking anywhere.
The flu is more dangerous than you may think.
Flu-related complications can put older adults at a greater risk for hospitalization, pneumonia, or heart attack.
Demand more from your flu shot. Sanofi higher-dose flu vaccines are proven to provide better flu protection than standard-dose flu shots in older adults. They’ve even been shown to better protect against flu-related complications.
See the studies page for full study design of our randomized controlled trials and real-world evidence.
Did you know?
In a study of almost 1,300 people 40 years or older, some people were approximately 10 times more likely to experience their first heart attack after having the flu.
Not all flu vaccines are the same.
You have a choice, so ask for the Sanofi higher-dose flu vaccine for your age

- With 4x the dose, it provides 24% higher flu protection compared to a regular flu shot†
- Studied for over a decade during 12 flu seasons (2009/2010 to 2019/2020, 2021/2022)
- Shown to provide better protection against serious flu-related complications in adults 65+ compared with a regular flu shot

In a clinical study conducted in 2011-2012 and 2012-2013 in approximately 32,000 adults 65+, the trivalent formulation proved to be 24% more effective at preventing the flu than standard-dose FLUZONE® (INFLUENZA VACCINE).
FLUBLOK®
- Clinically proven to provide 30% more protection compared to a regular flu shot in adults 50+‡
- The efficacy of the trivalent and quadrivalent formulations are related because both are made using the same process and have overlapping compositions
- The only vaccine that uses the flu virus's genetic makeup to guarantee an exact match to WHO- and FDA-selected strains
- With 3x more antigen than a regular flu shot
- In adults 18 through 64 years of age, the most common side effects were pain where you got the shot, headache, tiredness, and muscle pain. In adults 65 years of age and older, the most common side effects were pain where you got the shot, tiredness and headache. Other side effects may occur
‡In a clinical study of approximately 9,000 people conducted during the 2014-2015 flu season, FLUBLOK® (quadrivalent) (Influenza Vaccine) was proven to be 30% more effective at preventing flu in people 50+ vs FLUARIX® QUADRIVALENT (a standard-dose vaccine).
