简要总结
To determine the tolerability and immunogenicity of FLUVAL P monovalent influenza vaccine in adults and elderly people, with the objective to verify efficacy and tolerability of the study drug.
详细描述
Primary Objective:
To assess tolerability/safety (incidence of adverse events) of the study drug. To assess the efficacy (immunogenicity) of the study drug by serology testing of blood samples taken at Day 21-28 after immunization in groups and age groups.
Secondary Objectives:
To assess the long-term safety of the study drug 50-60 days after immunization. To determine the tolerability of simultaneous administration of FLUVAL P monovalent pandemic influenza vaccine and FLUVAL AB trivalent seasonal influenza vaccine in case of adults and elderly people.
To assess the efficacy of the study drug by optional epidemiological follow-up of the participants until the end of the influenza season.

- •Capable of understanding and complying with study protocol requirements;
- •The volunteers provide written informed consent prior to initiation of study procedures;
- •Absence of existence of any exclusion criteria.

- •Known allergy to eggs or other components of the vaccine (in particular mercury);
- •History of Guillain-Barré syndrome;
- •Active neoplasm;
- •Immunosuppressive therapy in the preceding 36 months;
- •Concomitant corticosteroid therapy, including high-dose inhaled corticosteroids;
- •Immunoglobulin (or similar blood product) therapy within 3 months prior to vaccination;
- •Documented HIV, HBV or HCV infection;
- •Chronic illness that, in the opinion of the investigator, may interfere with the evaluation of the immunoresponse;
- •Acute febrile respiratory illness within one week prior to vaccination;
- •Vaccine therapy within 4 weeks prior to vaccination;
- •Influenza vaccination within 6 months prior to vaccination;
