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.
Fight the flu with higher-dose flu vaccines from Sanofi. They’re 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 do have a choice, so ask for a Sanofi higher-dose flu vaccine
by name.

FLUZONE® HIGH-DOSE
- The #1 used flu vaccine for people 65 and older*
- Superior flu protection for adults 65 and older versus standard-dose FLUZONE® (INFLUENZA VACCINE)
- 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)
- Formulated specifically for adults 65+, with 4x the dose of a standard-dose flu shot
- In adults 65 years of age and older, the most common side effects were pain where you got the shot, muscle pain, tiredness, and headache. Other side effects may occur

FLUBLOK®
- Has 3 times the standard-dose flu shot
- In a clinical study of approximately 8,600 people (~4,300 in each of 2 groups),
FLUBLOK (Quadrivalent) was proven to be 30% more effective at preventing flu in people 50+ thanFLUARIX® QUADRIVALENT. - The efficacy of the trivalent and quadrivalent formulations are related because both are made using the same process and have overlapping compositions.
- Made with recombinant technology
- Egg-free and preservative-free
- 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.
