Study summary

Respiratory and gastrointestinal infections are frequent problems in children under 4 years of age, especially after the start of schooling. These conditions are facilitated by an incomplete maturation of the immune system and by the anatomical and functional structure of the respiratory and gastrointestinal tract still in development.

Functional foods derived from the fermentation of cow's milk with probiotic strains have been proposed for the prevention of infectious diseases in children. Several products have been investigated, sometimes with conflicting results. Some scientific evidence has shown that the administration of Vitamin D, Zinc, Beta glucan, 2'-Fucosyllactose can stimulate the immune defenses and reduce the number and severity of infectious episodes. In particular, 2'-fucosyllactose is one of the oligosaccharides of breast milk. It has both a prebiotic and immunoregulatory action since it is able to prevent the adhesion of pathogens to epithelial surfaces and subsequent translocation.

Healthy school-going children aged between 12 and 48 months, who attend school at least 5 days a week, will be evaluated.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

What researchers measure

Primary outcomes

  1. Primary outcome

    The primary aim of the study will be the percentage of children who will present at least one infectious episode (acute gastroenteritis, rhinitis, otitis, pharyngitis, laryngitis, tracheitis) diagnosed by the pediatrician during the 3-month study period.

    Time frame: The dietary supplement and placebo will be administered for three months from the date of enrollment.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Apr 2025 (actual). Primary completion is estimated for Sep 2025, 4 months after the start.

Of 274 non-industry interventional studies with no phase under Infections, half reached primary completion within 25 months of starting (the median), counting those still running; a quarter within 9 and three quarters within 51. This study's planned 4 months is below that.

Counting every sponsor, half of 305 studies reached it within 24 months; a quarter within 10 and three quarters within 50.

Infections covers many different conditions, not one, so the studies compared here vary widely. Read these figures as a rough guide.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 9, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
