Brief summary
To trial the reactogenicity, safety and immunogenicity of the Flu-M inactivated split influenza vaccine in volunteers aged 18-60 years
Detailed 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.
