Most of the studies have addressed response to Hepatitis B vaccinations. The other studies have all examined secondary response. It is unclear, however, whether these differences in antibody level are great enough to influence the degree of protection against infection provided by the vaccination. In a single study of antibody response to influenza vaccinations, Kiecolt-Glaser et al. Stress-induced modulation of the immune response to recombinant hepatitis B vacine.
Chronic stress alters the immune response to influenza virus vaccine in older adults.
Influence of perceived psychological stress and distress on antibody response to low dose rDNA hepatitis B vaccine. Relationship of stress, distress, and the immunologic response to a recombinant hepatitis B vaccine.
