Is the high-dose influenza vaccine better for people over age 65 years?

Abstract

Influenza vaccinations are one of the largest public health initiatives each year. The vaccine's components are varied, and the high-dose influenza vaccine was designed to provide better protection for older adults. Patients may request the high-dose vaccine due to a perceived superior benefit. This article describes the vaccine formulations and whether older adults require high-dose compared with standard-dose vaccinations.
