Brief Summary

Research studies have found a relationship between the immune system (how the body reacts to an infection) and the development of depression. As it is still unclear how they might be linked the investigators will use a typhoid vaccination to activate the body's immune system and will measure the response by looking at changes in sleep patterns.
