Study summary

The aim of the intervention is to examine the effect of the bacterial strain BB-12, provided for 6 mo, on the prevalence of infections and allergic manifestations in small children, and how BB-12 affects the immune system, the gastrointestinal tract and the microbiota. Children are enrolled during 2 winter seasons.
