Secondary Outcomes (3)

  • Clinical respiratory symptoms duration and frequency in children with respiratory tract infections upon administration of probiotic as assessed using the Monthly Health Questionnaire (as used in ClinicalTrials.gov (identifier number NCT02434042)

    12-weeks

  • Clinical gastrointestinal symptoms in children with respiratory tract infections upon administration of probiotic as assessed using the Monthly Gastrointestinal Questionnaire as used in ClinicalTrials.gov (identifier number NCT02434042)

    12-weeks

  • Immunity profiles in children with respiratory tract infections upon administration of probiotic via the use of oral swabs

    12-weeks
