Clinical Trial Summary

The goal of this clinical trial is to assess tolerability, reactogenicity, safety and immunogenicity of the Flu-M Tetra vaccine as compared to the VaxigripTetra vaccine in terms of prevention of influenza in children aged 6 months to 17 years old inclusive.


Clinical Trial Description

The trial will be conducted in three stages. • Stage I Participants - children aged 10 to 17 years (10 years 0 months 0 days - 17 years 11 months 30 days), will be vaccinated a single 0.5 mL dose of the Flu-M Tetra vaccine or the VaxigripTetra vaccine intramuscularly. Once reviewed by the Sponsor, the report will be submitted to the supervisory executive authorities alongside the notice of commencement of Stage II trial. • Stage II Participants - children aged 3 to 9 years (3 years 0 months 0 days - 9 years 11 months 30 days), will be vaccinated a single 0.5 mL dose of the Flu-M Tetra vaccine or the VaxigripTetra vaccine intramuscularly (double dose for volunteers who have not been vaccinated before). Once reviewed by the Sponsor, the report will be submitted to the supervisory executive authorities alongside the notice of commencement of Stage III trial. • Stage III Participants - children aged 6 to 35 months (6 months 0 days - 35 months 30 days), will be vaccinated twice 0.25 mL dose of the Flu-M Tetra vaccine or the VaxigripTetra vaccine intramuscularly. ;
