The effect of microbial exposure on healthy human subjects will be investigated. The volunteers will either receive material containing a microbial inoculum, or they will receive nothing. Changes in cytokine and IgE and vaccine response will be measured. Subjective well-being will be recorded. Changes in microbial community will be followed. The hypothesis is that microbial exposure increases the measured responses.
