Brief summary
The goal of The BEGIN Study, a randomized controlled double-blinded intervention trial, is to learn if probiotics, with Bifidobacterium longum subspecies infantis Bifin02 (B. infantis), given to healthy newborns can affect various health outcomes and to explore impacts of the infant gastrointestinal microbiome. The main questions it aims to answer are: * Does B. infantis probiotics impact immune function and does it lower the number of bacterial infections and use of antibiotics? * Does B. infantis probiotics impact overall health, development, growth and wellbeing? * Does B. infantis probiotics impact inflammatory diseases, allergies and autoimmune diseases Researchers will compare B. infantis probiotics to a placebo (a look-alike substance that contains no probiotic) to see if B. infantis colonization impact the human immunesystem and various clinical and biochemical health markers. Participants (parents) will * Orally administrate the B. infantis probiotic to their newborn child daily in three weeks from 7 days of age. * Answer baseline and follow up questionnaires in a study app * Take five stool samples from the child and one stool sample from the mother * Collect a 4 week of passive dust sample at home (Electrostatic Dust fall Collector) * Donate one dried bloodspot and one blood sample from their child
Interventions
1000 newborn children are randomized 50/50 to receive either B. infanits or placebo in a dietary supplement, for daily oral administration in three weeks from 7 days of age.
Identical looking placebo (without any probiotics/B. infantis) for double-blinded daily oral administration in three weeks from 7 days of age.

Other
| Measure | Time frame | Description |
|---|---|---|
| Mother HMO-secretor status | 1 month | The type of Human Milk Oligosaccharides (HMO) section in mothers' breastmilk, will be determined to exploratively study the relationship between types of HMO's, mothers HMO-secretor status and effects of B.infantis. |
| Atopic disease (adjusted SCORAD grading) | First assessment at 1 year | Atopic symptoms, eczema, registered in study-app with description of episodes of atopic dermatitis (adjusted SCORAD grading). Disease intensity is calculated based on six characteristics: erythema, edema, oozing/crusts, excoriations, lichenification, and dryness. Each characteristic is given a score between 0 and 3, where 0 is absent and 3 is severe. The scores for each characteristic are added together for a total intensity score of up to 18. |
