Summary
This study tests whether a daily probiotic supplement (Lacticaseibacillus rhamnosus CRL1505) can prevent upper respiratory infections like colds and flu in healthy children aged 3 to 12. Over 268 kids will take either the probiotic or a placebo for 12 weeks, then be followed for another 16 weeks. Researchers will compare how many children get sick and how often.
