Recently, the Spobiotic Research Center collaborated with Hanoi Medical University to conduct the study titled “Efficacy of Saline Solution and Probiotic Products in Preventing Upper Respiratory Infections in Children Aged 2 to 6 in Son Tay Town, Hanoi, 2024.” This study, led by Assoc. Prof. Dr. Nguyen Thi Hoai Thu, was reviewed and accepted by the Institute for Preventive Medicine and Public Health, Hanoi Medical University. This collaboration marks a significant advancement in probiotic research, aiming to support respiratory disease prevention in young children and reduce antibiotic dependency, especially in the field of preventive healthcare
This is the first study in the world to demonstrate the safety and superior effectiveness of nasal spray probiotics containing Bacillus spores (LiveSpo® NAVAX and LiveSpo® NAVAX KIDS) in preventing and reducing the recurrence of upper respiratory tract infections in children. Clinical trial results revealed that after 14 and 28 days of use, LiveSpo® NAVAX and LiveSpo® NAVAX KIDS effectively reduced typical respiratory symptoms-such as runny nose, sinusitis, hoarseness, pharyngitis, and tonsillitis compared to baseline and in comparison, with saline solution.
A key highlight of this research is the outstanding ability of LiveSpo® NAVAX and LiveSpo® NAVAX KIDS to prevent pathogenic viruses and bacteria, significantly reducing infection rates and the risk of viral infections such as including RSV, influenza, and rhinovirus, compared to physiological saline. Additionally, probiotics have shown the ability to regulate immunity, strengthening respiratory defenses and significantly reduce the rate of children needing to miss school or take antibiotics, anti-inflammatory drugs, etc.
The study received an “Excellent” by the evaluation committee due to its high applicability and safety for children. LiveSpo® NAVAX promises to become a potential solution in preventing respiratory tract infections, especially during the changing seasons, helping to minimize dependence on antibiotics in the treatment of respiratory infections in children.
