Study Summary

The overall goals of this study are to examine the relationship between chronic inflammation and threat and reward sensitivity, and to determine the effects of acute inflammation on threat sensitivity, in individuals with and without moderate to severe PTSD symptoms. The investigators will first conduct an observational study to examine the relationship between chronic inflammation and neural and behavioral measures of threat sensitivity. Then, the investigators will conduct a randomized, double-blind, placebo-controlled, between-subjects study to examine the effects of acute inflammation on neural and behavioral measures of threat sensitivity.

Primary Outcome

On visits 1 (baseline) and 2 (post-vaccine or post-placebo administration), participants will perform computerized threat and reward tasks and investigators will measure and compare neural activity between groups (PTSD vs. control) and condition (endotoxin vs. placebo).
