Life events, perceived stress and antibody response to influenza vaccination in young, healthy adults
Abstract
Objectives: Chronic stress has been associated with impaired response to influenza vaccination in the elderly. This study investigated whether mild, intermittent stress experienced by young, healthy adults has a similar effect.
Methods: Antibody and psychological status were determined prevaccination and 5 weeks and 5 months later; a fourfold increase in antibody to at least one viral strain was considered protective.
Results: At 5 months, unprotected participants reported significantly more life events and tended to report more perceived stress than those who were protected.
Conclusions: Psychological stress is detrimental to long-term maintenance of antibody levels following vaccination in young, healthy adults.
