The Effect of DHEAS on Influenza Vaccination in Aging Adults

Abstract

A one-time supplemental dose of DHEAS with influenza vaccination appeared to enhance the specific HI antibody response to the 1993-94 H3N2 antigen in a small group of older adults. These findings were limited to those with lower prevaccination titers and lower DHEAS concentrations. Although clinical implications of these findings for influenza vaccine are uncertain, these results suggest additional detailed immunologic investigations on the role of DHEAS in the aging human immune response are warranted.
