Clinical Trial Summary

Study of the Reactogenicity, Safety and Immunogenicity of Flu-M Inactivated Split Influenza Vaccine in Volunteers Aged 18-60 Years

Description:

All subjects will be followed up for 21 days post-randomization. The subjects will further be assessed at 2 days, 7 days, 21 days following the booster vaccination. Blood samples will be collected for reactogenicity and safety and immunogenicity assessments before injection and 21 days after vaccination.
