First seen Jan 03, 2026 · Last updated May 16, 2026 · Updated 23 times

Summary

This study looks at whether short-term changes in the immune system affect how people with PTSD process fear. Participants will receive either a typhoid vaccine or a placebo, then have their body responses measured while listening to sounds. The goal is to better understand the link between inflammation and PTSD, not to treat the condition.
