- Brief Summary
The study the safety, reactogenicity and obtain preliminary data on the immunogenicity of Flu-M Quadro, 4-valent inactivated split influenza vaccine, in healthy volunteers
- Detailed Description
The maximum period of the volunteers' participation in the trial will be 35 ± 2 days. Screening period - up to 7 days. The vaccine administration period is 1 day. Follow-up period - 28±2 days.
All volunteers are followed by a clinical investigator for 6 months after vaccination outside of this trial with the aim of detecting possible late adverse reactions. If a volunteer has any delayed-type reactions, the volunteer will be invited to the clinic for correction of his/her condition.
