Brief summary
The goal of this clinical trial is to learn how a mixture of human milk oligosaccharides impacts the development of the infant microbiota, the immune maturation and how the interaction between the microbiota and immune maturation may impact both short and long term health of the infant. The participants will: * Consume the investigational products (active/placebo) for 6 months * Legal guardians/parents to the participant to collect stool samples from the diapers at home * Legal guardians/parents to the participant to report gastrointestinal symptoms, signs of infections in an electronic questionnaire * Visit the clinic for checkups and dried blood sample collection For reference, a group of breastfed infants will be included. They will undergo the same procedures apart from consuming the investigational product (active/placebo). 230 participants (115 in each intervention arm) will be randomized to an intervention and 104 participants will be recruited for the reference group, giving a total sample size of 334 participants. The intervention trial will be reported in two steps, first step covering the intervention phase from birth to 6 months; and step two includes both the intervention phase (0-6 months) and the follow-up period from 6-12 months. Informed consents for the possibility to preform long-term follow-up will be obtained.
Interventions
Human Milk Oligosaccharides provided in a commercially available infant formula powder, fed daily ad libitum from enrollement to 6 months of age
An identical commercially available infant formula powder without Human Milk Oligosaccharides, fed daily ad libitum from enrollement to 6 months of age
