The senior dose is actually a higher dose: Fluzone High-Dose Quadrivalent contains four times the amount of antigen as the regular dose flu vaccine. As we get older, our immune systems have a harder time fighting off infections and learning from vaccines. The higher amount of antigen in the high-dose flu vaccine helps an older adult’s immune system better recognize and react to the vaccine.
