- Conditions
- Vaccine ReactionVaccination; InfectionInfluenza, HumanInfluenza Viral InfectionsInfluenza
- Interventions
- Biological: Influenza vaccine [inactivated]
- Registration Number
- NCT05869201
- Brief Summary
The goal of this clinical trial is to assess tolerability, safety and immunogenicity of the Flu-M Quadro vaccine as compared to the Ultrix® Quadri vaccine in volunteers aged between 18 and 60.
Participants were given Flu-M Quadro \[inactivated split influenza vaccine\] with preservative or Flu-M Quadro \[inactivated split influenza vaccine\] without preservative or Ultrix® Quadri vaccine.The volunteers of each group were vaccinated with a single dose vaccine.
Researchers assessed the tolerability, safety and immunogenicity of the Flu-M Quadro quadrivalent inactivated split influenza vaccine.
Researchers performed a comparative assessment of the tolerability, safety, and immunogenicity of the Flu-M Quadro quadrivalent inactivated split influenza vaccine and the Ultrix® Quadri vaccine.

- According to the medical history, the volunteer was/is a patient of a tuberculosis dispensary and/or narcological dispensary and/or neuropsychiatric dispensary and/or other;
- History of acute infectious diseases (recovery less than 4 weeks before vaccination);
- Consumption of more than 10 units of alcoholic drinks per week or history of alcohol addiction, drug addiction or abuse of pharmaceutical products;
- Smoking of more than 10 cigarettes per day;
- Participation in another clinical trial during the last 3 months;
