“For the elderly, bereavement or an unhappy marriage may weaken the effectiveness of a flu vaccine, but other stresses do not appear to affect the immune system’s response to the shots, as they do in younger people.

The participants also filled out detailed questionnaires about recent life events, social support, marital status and satisfaction and health habits. Finally, they each received a flu vaccine effective against three different strains of virus. The results appear in the May issue of Brain, Behavior, and Immunity.”
