The flu is more dangerous than you may think

Flu-related complications can happen at any age and can put you at greater risk for hospitalization, pneumonia, or heart attack.

Fight the flu with Sanofi flu vaccines, which help prevent flu in older adults. They’ve even been shown to provide better protection from flu-related complications compared to standard-dose flu shots.

See the studies page for full study design of our randomized controlled trials and real-world evidence.

For adults 65+

  • 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)
  • Compared to Fluzone®, the most common side effects were slightly more frequent and included pain and redness at the injection site, muscle ache, tiredness, and headache
  • The immune response and side effects of FLUZONE® HIGH-DOSE QUADRIVALENT were similar to the trivalent formulation in a 2017-2018 clinical study in 2,670 adults 65+. FLUZONE® HIGH-DOSE QUADRIVALENT is expected to provide better protection against the flu compared with standard-dose quadrivalent flu vaccines
  • Formulated specifically for adults 65+, with 4 times the standard-dose flu shot
